This reminds of an old joke about a repairman who was called in to fix a household appliance. He said "It's a bad screw, it'll be $100 to replace" The owner was in shock, $100 for a screw??? Repairman explained "well, it's $1 for the screw and $99 for knowing which screw to replace!!!"
@@artgoat that's the investment once you know you how to fix things you get things for the low and can resale them and make your money back ain't nothing too complicated 🤷🏻♂️
That is so amazing to hear! Thank you for sharing. Keep it up!

A technician telling you you how to fix your telly and showing you you why some technicians charge so much money for a small job most television companies discourage technicians and make sure that most parts are not always already available they don't want me to fix their tellys they want you to buy a new one it's nice that this man takes the time to help others shows you you once again there are good technicians out there honest and out there to inform the public about how they're being ripped off when they buy a telly and how it breaks down and so easily could be fixed but many technicians would rather charge a higher price for a small job this man showing you you can fix your telly and if you have a decent technician who is honest and decent like this one he won't rip you off a charger for a price
I repaired TVs for 22 years, starting with sets that still had tubes, later transister and finally IC chips. The new technology works great and has excellent features, but is too small for this old guy. It's a young man's technology these days. Bravo to you working with such tiny components.
Thanks! Working with a microscope makes it very doable. In order to record this video I couldn’t use my microscope and instead had to watch through the tiny screen camera which is partly why I had trouble holding the transistor steady. I just upgraded to a trinocular one so hopefully videos like these will be easier to record.
The good old days. Technicians back then used to do things like design and build their own Pay TV Decoders. My version, cost about $5. It did not require a power supply of its own, since It pulled only 15 mA, and thus you could just install it inside a TV converter and then tap the power from the TV converters 12 VDC line instead. The decoder PCB was 4.50" x 1.20". To install, you just had to cut the baseband video wire, the wire that leads from the demodulator to the modulator, and hook these wires up to the decoder PCB's input and output. Anyhow, it decoded the baseband video signal line by line, rather than use the complex frame by frame PLL method. Later on I tried to sell the design to a cable company. But they said that my design was too good. Meaning that it was far to easy for it to be copied, due to it having so few components, components that were also readily available to just about anyone.
Yeah i remember i was kid and a family friend come to us to fix our black and white tv....watching for hours searching the fault and the smell of the dust and hot tin i will have in my memory for ever.
Well I was wondering if you could help me with a problem I have a 55 in LG TV that I bought off someone and it had a picture perfect picture on the internet part you know show settings and all that but when I brought it home to hook it to my internet it kept saying put in passcode I put in Pasco says it again so I tried to hook a DVD player up to it and the screen turn white and fuzzy it has sound but you know it's white and fuzzy picture but when I unplugged the DVD player it just has sound and I don't know what it could be it doesn't have pictures you know of people or anything on it like it should have but it's perfect when you go to settings it's like nothing's wrong with it on settings
Super valuable video for a common fix on the TCON board for these Vizio models. I can't thank you enough; Vizio is all my family uses. Thanks for the tool descriptions in the notes above as well, also valuable info. These are the fixes that never make it to any manual, and it's so cool you took the time to explain it.
If you don't have the tools you can also use a cheap soldering iron of around $25. To remove the broken component, heat each solder joint separately and use a sharp knife to bend up the pin while the solder is heated, so it's not touching the solder anymore. To solder on the new component, put the new component in-between some tweezers and lower the side with the single pin just a little, so this side touches the solder joint first. Heat the solder while lowering the component in place. When the side with the single pin is soldered, the pins on the other side should slightly touch their solder-pads underneath, then complete soldering by alternating between both left over solder joints. If you notice you are bending the pin on the other side a little to much, just reheat this side quickly to release the stress on this pin.
or you can use a lot of solder, just make a big glob that will get cold slow and take the part out with tweezers. Clean the pads with a wick, place component, solder 1 leg while holding the part and then solder the other 2. Much easier and cleaner.
The amazing thing is how little is actually wrong with these tv's. This is a wonderful channel to clarify exactly how you fixed these models. I can't wait to take another look into my bad tv because it could well be some very inexpensive part(s). Very helpful! I enjoy fixing stuff too.
Great clip! I was a TV repairman (old analog TV). Your video is really good, especially for techs, but I doubt an average person could do such repair (mostly due to the lack of tools and patience).
I did the same thing with my 3k, 10 yr flat screen by replacing four capacitors for $1 plus $4 in S&H 2 yrs ago. It was the first time my adult son got the chance to watch what his mother use to do for a living when he was a toddler. It impressed the hell out of him, lol !
I garbage picked a gateway plasma going on 6 years ago (I fixed it on July 4th while I was off). Replaced $12 worth of capacitors on the power supply board and a sub sound board it has. Still working today.
He needed to use his right hand to hold the transistor, and his left to hold the heat gun, he would be more stable using the hand he is more used to using for small parts.
First time I see this man.... I paused the video at 0:19 Because that's enough for me to subscriber Coming back later to watch more...... I love people like this on UA-cam.
If you search online there are forum posts and even other videos that explain this transistor is a place to start your diagnosis. I didn't spend very long on the diagnosis since others had helped point it out. The internet is a great place to help solve problems.
@@Sal112350 you are incorrect, sir... continuity is a great way to test... but, he failed to actually prove that the part was the issue. He should have tested the continuity on the board again AFTER the apart was taken out to show that the part was causing the short and not some other component on the board. THAT is the proper way to do a continuity check.
@Derp The answer to your question, Derp, is bad design. The transistor in the circuit is running "hot" (over 70% capacity) regularly and if the transistor quality is weak it will go again over time. But this knowledge has little barring on the propose of Frugal's presentation. He tested the part, it needed replacement, and he showed how to do it. If a person watching tests the part and it isn't shorted... they should find a different video to fix their problem :-) .
@Derp You sir, are correct. After doing this kind of work for around 40 years, knowing to check components on the secondary side (for the lack of a better term) of this transistor is a must. If another part is shorted, leaking, etc., it's pulling too much current through the transistor so it failed. Sometimes you get lucky. Lot's of times you don't. If that transistor popped, what does ''the internet'' say then?
OMG you a tech genius, u saved a tv that had the exact problem but different model my tv was model 43R6E3 and it worked! Thank you for the pointer as soon as I saw the video I knew we had the same problem.
Great how-to video. You explained it well enough so that I feel confident enough that I could do the repair on my own TV if need be. The link to Ali-express for the soldering iron and hot air combo was a nice touch because although it is cheap equipment, it would probably last long enough to make a few repairs and save me the cost of replacing the entire TV.
Nice job on the video. Very clear photography. I really thought this would be a video about a bad capacitor. I have a ~15 year old LG 27" 1920x1200 monitor that I fixed many years ago. I learned what was wrong by searching the Internet forums. My search taught me about "capacitor plague." Ballooned cheap knockoff capacitors that caused many electronics to prematurely fail. I replaced the bad capacitor and my LG is still going strong today. I agree with you. The Internet is a wonderful resource for DIY'ers.
I fixed our Samsung a couple of years ago - replaced a couple of transistors on it. Great tutorial! Looks like you’re channel is doing great! Thanks for subscribing to mine. 👍
Hmm...you too can fix a flat screen TV for $0.54...if it happens to need this particular transistor, never mind how we diagnosed the failure, and you have a hot air rework station. I once saved a stereo receiver with a $1 capacitor, too, but that was the only lucky shot I’ve had. The other jobs took a lot of troubleshooting and had more involved failures.
he coulda fixed it with just a soldering iron. but I understand what you mean. my mate fixed a four-year-old 60inch telly using NO parts. (just squeezed up a screen connector). but I think it's worth having a look if you have a few tools and basic skills - if you can't fix it, there's nothing lost. if you can it's a result
Hi Fugal, thanks for the video. I suggest you adjust the air flow on your hot air gun as surrounding SMT components may be blown away, and you can notice that in the video when the diode above the transistor started sizzling, and if they don;t get blown away their soldering will dry out hence making it a dry joint. The trick is to use a good heat with less low air flow, that way the heat contact is precise on the bad component.
I agree. This is not my best work. I was excited plus I couldn’t really see what I was doing since my camera was so close and covering the board. I have a microscope camera now so that won’t happen again (hopefully).
I designed and installed my own 15,600W solar panel system on my house. It will be a new video series later this summer (after a few more videos like this one) Check out a sneak peak on my website: frugalrepair.com/solar/
I myself loves to tinker alot with electronic stuffs. I hope to learn the troubleshooting skills you have, not just the visual check. So, with this, you got a new subscriber! 😁😁
A popular question I have been asked is: "Are you making more videos?" Yes! I took a break from making repair videos to design and install a 15.6 kw solar system on my house, (more on that to come) but for now, here is the latest video: ua-cam.com/video/fesJGOLurBg/v-deo.html
Such a coincidence, a friend of mine was about to do that same, same exact model. Took it apart and pulled out the board. Did a multimeter test and the results were the same. Now I just need to put in an order for a new one. I really hope this works because my Xbox is lonely. Ill let y’all know what happens when I get my transistor. 07 salute!
I like fixing stuff (cars, Electronics, i.e. whatever breaks around the house) and nothing compares to the feeling of knowing you just saved your self big bucks or, even better, now can sell something that was worthless yesterday. I've got a couple of flat screens that you've encouraged me to tackle now. Cheers
@Enoch Pedersen I put the specs in the description so anyone can hunt down online for a good price/option. I'd would first check on aliexpress if you can wait for it to arrive from China. Otherwise, check with any of the US suppliers.
@@FrugalRepair i have the same tv model but the 70 inch .....e701i-a3 with the same exact problem. so this will work with the exact part u replaced with?
@@MrHontas83 The tcon board would be the same. You would need to either test the tcon board for other failures in addition to this transistor to make sure or you can replace the transistor and see if it worked. It is very possible that there are more bad components on the tcon and it is possible that your lcd is bad and thus not repairable. You can also simply buy another tcon board on ebay for like $17 and pop it in quick to see if it fixes the tv.
How didnt you see the moment where he is measuring that very component.... It isnt that far fetched that understanding its inner workings it is much easier to go and look for failed components. Because they are most commen to fail just hard to find if you dunno what is controling what. Just grab yourself some broken tv a multimeter and go have some great fun. But remember to stay away from the high voltage area...,if you dont you find out really fast why. Good luck! Stay safe!
Most issues like this can be quickly checked with under $150 in tools, and a quick google search of " common problems". I have done this numerous times for all sorts of various electronics and it has saved me not only thousands of dollars in repairs, but hundreds of hours of manual troubleshooting.
Good instructions thanks. This might be the repair needed for one of my two Vizio's crashing in the same two weeks. I'll explain both situations and hopefully you can share your thoughts on diagnosis. TV. #1, Backlight certainly works but losing color, contrast and brightness as the picture is starting to blacken out in top left corner and bottom right...almost is rectangle shapes in each corner. Picture is good after a rested restart and the problem quickly creeps back in. TV. #2, our oldest Vizio maybe 8 years, 50". First sign of a problem was the quick App start brand bottoms at the bottom of the modern FireStick would change the TV input to an unused port. Next problem it would blackout and flicker back on with clear white horizontal lines. Then it flickered until it don't come back. After long rests it worked again a couple times, V logo came up, with sound, and was back out within 10 minutes. Now it's out-out with no sound of the FireStick clicks changing the Apps, no V logo and all black screen...no backlight. With was a 2 month fading experience from beginning to end.
Most solder has flux in it and also I would never use hot air station its risky and for repairing one thing its pointless. Just use a soldering Iron it's cheap and it works well and its safe if you use it right.
My thoughts exactly.. For a 3 pin component it's useless. Just pump the solder from the board, put the transistor on place, and solder it with a simple iron..
Who needs a solder suction pump for a job like this? Just use solder wick. Should have cleaned off all that excess solder so the new part leads are in contact with PCB with minimum solder in between. That huge pile of solder this guy used is more likely to crack than if it were minimal.
Also soldering one leg to tack it in place with an iron is easy and then you only have to touch the other pads after you have cleaned and added new solder to the pads.
It's repair 101... (1) look the board over with a magnifier, are there any burn marks (change the burnt stuff) are there any dry joins (reflow them) are there any board cracks or scratched traces (bridge the gaps with wire), are any caps leaking shit (change them) (2) Check voltages Mains, DC voltages at chips etc (3) test shorts/continuity on fuses (should be), transistors (shouldn't be), caps (shouldn't be) etc etc... most of it is common sense...
There I no such as a visually leaking cap...wives tale extension there is no leak you can actually see in a leaking cap It just means the cap is leaking voltage not leaking a substance so...you have never fixed anything by finding a leaking component since there is nothing to leak out of it. b.s. called you shant recover back peddling not allowed it's just a bad lie but why did u lie there's a deeper reason me think
Lie no such thing as a visually LEAKING CAP there isn't anything TO LEAK OUT only voltage drops that what leaking means ya moron not like a substance leak so I gues you have x Ray vision I f you can see leaking voltage lol ....I hate b.s. liars
kirk watstien - you ain’t seen nothin’ yet if you haven’t seen a visibly leaky aluminum electrolytic capacitor. They have a discharge vent on the PCB end, and the leaked electrolyte is often visible on the board. And they will also pop their lid, which is quite visible. No BS to this, you just haven’t had enough experience with all sorts of varied devices to have seen those.
Thank you for this great info! I replaced the culprit mosfet with a random mosfet I desoldered from a random board. The tv turned on for a few minutes before blacking out again. This confirmed your suggestion that the mosfet is burnt. I can now go look for the correct spec mosfet to repair my tv. Tv is a SONY KDL-70R550. It’s an old dog but if it costs 50cents and a bit of sweat to repair I’m happy to continue using it.
I couldn’t find the mosfet of the exact spec that you specified so I tried my luck with a SI5328DS mosfet rated for 100v. It works and the tv is back working
schematics.... many of electronicians don't use schematics for fixing boards, we uses them 20-30 years ago, now theire not avaiable for the most of them. So, we tests, we try, and maybe we fix...
@@leso204 1206 SMD models (and biggers) are not so hard to tests and replaces, but for the tiniests ones (402, 201 and smaller), i'm ok with you, what a pain to try to test and even more to replace :/
You mean that there is a scratch in the screen? You probably can't fix it but you can minimize the damage a little bit. The part you touch on the lcd panel is the front polarizing film. That is glued on to the lcd with clear adhesive. Its been a while but depending on what kind of scratch and how deep, I've used a pencil eraser or a black permanent marker to mask some of the imperfections.
I'm not super into TV watching, but the info you're giving out here is too good not to subscribe to and consume in my free time. I see so many people throwing out TVs and I'm sure most of them require only simple repairs. Thanks for making all these videos.
@@FrugalRepair I just watched it. It's amazing all of the tricks you have picked up repairing these TVs. I actually have a 50" Samsung Plasma TV that has one green vertical stripe. It started doing that at 1 year of age and I just quit using it. Since I never throw anything away, I still have it. I'll have to peruse your channel to see if I can look for pointers on repairing it. Of course, it was replaced with a 4K LED TV that blows it away, but it'd still be fun to repair it. I originally came to your channel to show a friend how to look for lightning damage to his TV. Thanks for putting out such useful content and taking the time to help so many. You're banking a lot of positive karma.
Thanks, that’s encouraging for me to hear! Lines on a plasma maybe a relatively easy fix. It is possible (but I don’t really know in your case) that the ribbon cable needs to be cleaned and/or re-seated. You need to have the tv unplugged then locate the ribbon that controls that section where the line is. I bet there are videos about it. Those ribbon cables are usually at the bottom after you take off the back cover. Usually they are connected to the Z-board. You can google that.
Newer TVs are easy to fix now even if you do not want to change a transistor you can buy the boards cheaper than buying a new TV and just replace the board. I have fixed a few TVs over the years. The old tube TVs were easy you just pulled the tube out, took it to Radio Shack and got a new tube and replaced it lol.
No doubt the TV repair chains lobbied for tv's with no tubes so you'd have to pay a technician an outrageous fee to replace a 5 dollar circuit board. I remember fixing my own TV many years ago by testing for those burned out tubes. Cars were owner repairable also.
Wilcon Barro Yes. As with most repair jobs of any type, you will need tools. They probably cost a lot less than the repair shop or the price of a new TV though.
Multi meter is like 20 bucks at Walmart. Soldering iron 10-15 Flux 3-4 bucks or free with soldering iron "Fume extraction" get a house fan Hot air shit not necessary and most likely you'll damage something else if you don't know what your doing not worth the risk
I just picked up a vizio 47" tv for free the seller described it as the backlight went out on the right side, so I brought it home (this is my 5th tv I've fixed from my crona quarantine away from school for the past months thanks to you! Btw lol)well I decided to plug it in to see if they where correct and all the sudden I hear it squeal and smoke comes out of it!!😂 well I take it apart and look at the backlight inverter on both sides sure enough the right side was burnt from the capasitors smoke and the left side capasitors where bulging so I ordered 5 new ones I only need 4 but why not have extra lol for $6.99 and now it's running perfectly strong and has been for a week. Sorry for the long read but I figured I'd put my story if it might inspire someone to get after there broken tv and fix them.
Jon C. - unnecessary for this particular component with three leads. If it was a chip with lots of leads, then a soldering iron won’t be the tool to use.
Samsung TV's from 8-10 years ago were notorious for a bad batch of electrolytic capacitors. The company did a great job of repairing as many TV's as possible within a reasonable warranty period but you can only do so much. I repaired one 2 years ago that was out of warranty, for a friend. Capacitor kit was $12, shipping was $8. I volunteered my time(less than 2 hours) For $20 she had a functional 46" TV. Still works great today.
I know this is old but you just gained a new sub, i have 2 65" tvs that were replaced by LG a 2016 model and the other a Vizio 2018 model by Best Buy...i followed this Video and fixed both now i have 2 new 65" Vizios and a decent LG..THANKS
May I please ask you a few noob questions, I am not criticizing you but honestly try to learn from you:-) 3:22 why do you choose hot air instead of bent thick copper wire wound around your soldering tip? why do you not use something like capton tape to shield the other components from the hot air? Hope you please will teach me, so I better understand.
I hadn't thought about bending coper wire on a thicker soldering iron tip. That is a neat suggestion if you don't already have one with a fine tip. It still might be hard to solder in a small component in a tight spot with that setup. I'll have to try it sometime. I didn't feel the need to add kapton tape since the nozzle is small enough and the hot air can be directed to the one component. It depends on what work you are doing though. When working on an iphone board, for example, I may use kapton tape and place a metal coin nearby to help absorb some of the extra heat.
@@FrugalRepair Thank you for your great answer. About the copper wire, I find a thickness that I seems to fit the task and then start to bend it until it sits nice around the chip and let the tweezers and heat do the rest:-) Also wary nice and hard to reach places, like under a capacitor, in the corner near some plastic. You can always put an insulating tube around the 4 inch long copper, if necessary. :-) Your explanation about the heat gun, do make a lot of sense, I do just not have enough confidence and knowledge yet to dare that. It takes a bit of knowledge as you clearly have!:-)
Hi, i just want to thank your video, mate. I repaired a Sony 60'' with the same symptom. But in addition in my situation, i had to cut the left cof tabs. The MOSFET used in my case was the Si2308BDS.
@@fleximo3734 Not required on the title , he got it for free then had to spend 54 cent.. so yes its a 60'' Vizio he got for 54 cent ( .. plus his own work time )
@@yanz1232 Title is simply missleading because it says he got a 60" tv for less then a dollar when actually he bought a component to fix/repair it. Yes he got the TV for free and cost him less then a dollar to fix it.
As an EE, I salute you for the knowledge of an appliance, plus the incredibly small working parameters. I've never thought of using a heat gun in lieu of an iron, however small.
Question is how did you know out of all those components that one transistor was bad? Did you test all the components on the display board or something?
He literally explained that this was just a suspicion before testing. Many repairmen work like this. You don't have the time to check everything so you just move down a list of parts that have a high likelihood of failing. If this TV is known for a particular part failing then why even bother with the other parts?
Touch a 300v capacitor and it'll enlighten you to the dangers of home TV repair. That being said its a miracle my heart hasn't exploded over the years.
I mean... we got taught that if we ever wanted to open anything with big capacitors we should wear protective gloves and prioritize discharging of the capacitor.
@@X934YZK, No one is claiming perfection. It's simply about avoiding damage to the board. Rocking a component like that before the solder reaches it's melting point, can rip the pad right off the board. Definitely not a fun situation to deal with.
I have a 60 inch LG plasma that needs a similar repair. But I’m so scared To break it even more and I’ve never seen the tools you’re using before in my life other than just a basic solder gun. The TV is 600 W to run but it’s bright as the sun and crisp as a rainbow. I repaired it once by replacing the motherboard but accidentally gouged a little piece of solder.. stopping it from Booting up all together. I’m very confident that your technique will allow me to repair this incredible plasma. Just need to know more about the tools to get me there
Typical in any sort of repairs, the part is cheap, but the knowledge and know how, takes years. And it appears, very steady hands, and the tools to do the job. Nicely done. While I was younger, and better eyesight, I may have been tempted to try a repair. These day, I’d throw it out and buy a new set. Or if I were lucky, find someone with your skills and pay for your talent.
Thanks for your comment. Actually with the internet diagnosing a board that has a common failure doesn’t have to take very long. It is because other people find the faults and share the info online. Those issues that no one has come across before (or posted about) are ones that can take a bunch of time to track down the culprit(s).
Testing multiple things, then put back together, then make video. Or.... research issue on model and see it is very common failure, then make video hoping it works ..
You probably can't know ahead of time who makes the TV until you open it up. Vizio doesn't make the TV's actually. Usually the manufacturer is LG, AU Optronics, or even FoxConn (who makes iphones). I've even seen the same exact vizio model made by different manufacturers.
Just found your channel, the issue with my vizio is all the input ports stopped working so we cant plug anything into it. Lots of great stuff on your channel, I also try to help people save money by fixing thigs. Thanks for sharing.
@@FrugalRepair :) ty. Maybe not many years but you have a background to do this. I understood the real meaning if this vídeo. I didnt meant to be rude...
@@FrugalRepair at all. Actually I think using a heat gun was the hardest part. For one component with three leads you could of even used just solder and a soldering iron and popped one lead or leg at a time. But doesn't matter the job got done and the set now works.
That part was big enough not to use hot air, but if you do, solder paste works much better than wire. Melts more evenly and you don't have to keep tweezers on it. It also might help if that board had some heat sinking. Thanks for the video!
Most parts cost pennys its not some miracle here .the rest price for repairs comes with cost of tools, experience ,knowledge , rent ,workers ,vat And many other things.most people will break fixing.please at least tell people with risks opening TV by getting shocked etc.To me this video informative because i do fix stuff.for other canbe last thing they touch 🙌
@@haydeepoll927 Just realized I wrote "can't" instead of "can". Tcon boards are fairly inexpensive so that may be a better way to go. ebay usually has lots of them.
it would be interesting to show the diagnostic procedure and not just replacing a transistor, everybody can replace a transistor. testing the transistor on circuit is useless, more than often there is dc path around them by resistors and other components or even some other shorted component can create a dc path around the transistor. also that transistor is shorted but if it was open like often happens the beep or continuity test would be useless, it doesnt beep so in your line of thought it is good. try to go a little more in depth next time please. if somebody is uneducated in electronics hthey will learn nothing from this video and if the person has electronic knowledgde they will learn nothing either
I don't know if I would agree that "everybody" can replace a transistor. I understand you may want more in-depth board level diagnostic explanation but that isn't really the point of why I made this video. One of the big points of this video is to inspire people that things can be repaired inexpensively and I give an example of how it can be done on a tv that would otherwise be thrown away. If you happen to have the same t-con board and it failed, at least I've helped you with a starting point in your diagnosis and repair. And yes, there could be other damaged components but in this case, it was the only issue (like in many cases) and the tv was repaired.
@Prottoy Nahian nearly all youtubers list the products they use in the description. He didn't make a big deal about any of the products, not at all dishonest.
Hugo... other way around. Maybe 1 in 10 of my 1990s computer engineering class could solder and almost none of use would solder surface mount parts on an existing board. I spent four years on design and assembly involving such hands on work and I never got good enough to solder surface mount components. I would have attached wires to the transistor and soldered the wires on -- rather than try surface mounting such a tiny component by hand. Anyone with the skill to solder surface mount parts by hand can trouble shoot a board -- they are either in repair or assembly work with the later trouble shooting their own work. Nor is it a terrible interesting video to look where the video power on/of line in coming in and then track its path and touch both ends with a multi-meter.
Than you for the encouragement! I think I did a better job explaining the soldering process on the 65” 4K TV video. Did you get a chance to check that one out?
Screwdriver $4.00 Multimeter $154.99 Electronic toolkit $30.00 Anti-Static Soldering Mat $20.00 SMD Transistors $0.54 Hot air station $637.00 Solder Station $703.78 Fume Extraction Station $69.99 Total: $1,620.30
heart surgery has also only 2 $ materials cost , but you pay 300.000 $ for it. This is wrong way to put things into perspective. it's never about the material cost but the skills.
I see your point but I would argue this is different. You don't need to repair your tv, you can buy a new one at the store. But if yours is broken and you are going to throw it away anyway, then why not give it a go and try to fix it yourself? In the case of this tv, you can literally buy a new tcon board on ebay for $17 and put it in very fast. What I am showing is that you can do even better than that if you wanted to try. And you don't need expensive tools, buy a cheap soldering iron or hot air station and watch a few videos to educate yourself.
I agree with you. You and me can do that. But the title "for less then 1$" degrades the value of our work implying to others that our work is cheap. e.g. here is true story : there was a TV repair shop in my city, after his TV was repaired customer asked what was wrong with his TV, and the owner said, it was a resistor. Then customer left and actually brought the new resistor to the owner, and said here is it. It is dangerous to reduce the work to the cost of spare parts, leaving out the practice and eduction of decades, because the most people don't get it.
replacing those logic board still cost less than buying new tv...the expensive part is actually the LCD which i can assure you if your LCD is broken it could cost almost the same to buying new TV...maybe more than 80% of the cost from buying new TV...while replacing new logic board maybe cost like 10-20% of new TV...but if you have the skill repairing the logic board sure cost less...but if you dont have the skill replacing logic board is easy and should not use much of skill..so even if you send to repairman they should charge less if only replacing the logic board...
Superb fix - So many flat screens being thrown away nowadays simply because of faults/issues like these which can ultimately be repaired with knowledge.
Yes, it happens all the time. Usually it is a fairly simple fix. In this particular model you don't even need to go to the component level like I did. You can easily buy a new tcon on ebay for like $20 and with a screwdriver replace it.
@@dannygjk It's usually not a problem, just send it back for a refund. Even ebay sellers who have a "no return" policy will almost always (since they care about their rating) will take things back.
Thanks for sharing, in this day and time we need to change our way of thinking. With the pandemic that has arrived there's going to be a point where there will be issues of being able to afford the luxury items that we have been accustomed to buying. We are definitely going to need to repair what we once threw away, or the option will be to do without. If one thinks that the Great Depression was only a thing of the past, you're in for a surprise. You've earned a new subscriber.
You dont just wake up one day with all the tools and knowledge of a skilled trade...!? Wtf We should complain to the government about this discrimination against ignorence.
And still cheaper than buying a new 60", plus those tools can be used over and over to save even more money. But most folks go for the convenience of replacing today's flood of crap quality products. But manufacturers know this about human nature, hence the intentional crap quality. Convenience saves time, but costs you far more than you realise over the long term.
You do not need a hot air station. Just use some chip quick and tin all the pads and slide off the old transistor. Then make sure to wick the rest of it off then solder the new one. Both methods work.
My 60 inch is working just fine, but after seen this video im just gonna open it for the hell of it and see what i can FCK UP so then i can fix it. LOL 😜😜😜😜😜😜😜🤪🤪🤪🤪🤪🤪🤪🤪🤪
I did tv and radio servicing C&G 224 many many moons ago, it was all analogue back then everything was solid state..... very easy to fix compared to these smd's you deal with, respect to you.
Thanks! The biggest hurdle I find is lack of schematics and board views. It takes a lot longer if you have to reverse engineer stuff to figure out the problem.
I installed a 15,600W power plant on my roof by myself. Check out the Video --> ua-cam.com/video/ToxFObjnlF0/v-deo.html
This reminds of an old joke about a repairman who was called in to fix a household appliance.
He said "It's a bad screw, it'll be $100 to replace"
The owner was in shock, $100 for a screw???
Repairman explained "well, it's $1 for the screw and $99 for knowing which screw to replace!!!"
It's $0.54 for the component, $15 for shipping, $150 for hot air rework station, $75 for solder station...

That is so amazing to hear! Thank you for sharing. Keep it up!
A technician telling you you how to fix your telly and showing you you why some technicians charge so much money for a small job most television companies discourage technicians and make sure that most parts are not always already available they don't want me to fix their tellys they want you to buy a new one it's nice that this man takes the time to help others shows you you once again there are good technicians out there honest and out there to inform the public about how they're being ripped off when they buy a telly and how it breaks down and so easily could be fixed but many technicians would rather charge a higher price for a small job this man showing you you can fix your telly and if you have a decent technician who is honest and decent like this one he won't rip you off a charger for a price
I repaired TVs for 22 years, starting with sets that still had tubes, later transister and finally IC chips. The new technology works great and has excellent features, but is too small for this old guy. It's a young man's technology these days. Bravo to you working with such tiny components.
Thanks! Working with a microscope makes it very doable. In order to record this video I couldn’t use my microscope and instead had to watch through the tiny screen camera which is partly why I had trouble holding the transistor steady. I just upgraded to a trinocular one so hopefully videos like these will be easier to record.
The good old days. Technicians back then used to do things like design and build their own Pay TV Decoders. My version, cost about $5. It did not require a power supply of its own, since It pulled only 15 mA, and thus you could just install it inside a TV converter and then tap the power from the TV converters 12 VDC line instead. The decoder PCB was 4.50" x 1.20". To install, you just had to cut the baseband video wire, the wire that leads from the demodulator to the modulator, and hook these wires up to the decoder PCB's input and output. Anyhow, it decoded the baseband video signal line by line, rather than use the complex frame by frame PLL method. Later on I tried to sell the design to a cable company. But they said that my design was too good. Meaning that it was far to easy for it to be copied, due to it having so few components, components that were also readily available to just about anyone.
Yeah i remember i was kid and a family friend come to us to fix our black and white tv....watching for hours searching the fault and the smell of the dust and hot tin i will have in my memory for ever.
Well I was wondering if you could help me with a problem I have a 55 in LG TV that I bought off someone and it had a picture perfect picture on the internet part you know show settings and all that but when I brought it home to hook it to my internet it kept saying put in passcode I put in Pasco says it again so I tried to hook a DVD player up to it and the screen turn white and fuzzy it has sound but you know it's white and fuzzy picture but when I unplugged the DVD player it just has sound and I don't know what it could be it doesn't have pictures you know of people or anything on it like it should have but it's perfect when you go to settings it's like nothing's wrong with it on settings

Hey man, you doing ok?

Super valuable video for a common fix on the TCON board for these Vizio models. I can't thank you enough; Vizio is all my family uses. Thanks for the tool descriptions in the notes above as well, also valuable info. These are the fixes that never make it to any manual, and it's so cool you took the time to explain it.
If you don't have the tools you can also use a cheap soldering iron of around $25.
To remove the broken component, heat each solder joint separately and use a sharp knife to bend up the pin while the solder is heated, so it's not touching the solder anymore.
To solder on the new component, put the new component in-between some tweezers and lower the side with the single pin just a little, so this side touches the solder joint first.
Heat the solder while lowering the component in place. When the side with the single pin is soldered, the pins on the other side should slightly touch their solder-pads underneath,
then complete soldering by alternating between both left over solder joints. If you notice you are bending the pin on the other side a little to much, just reheat this side quickly to release the stress on this pin.
or you can use a lot of solder, just make a big glob that will get cold slow and take the part out with tweezers. Clean the pads with a wick, place component, solder 1 leg while holding the part and then solder the other 2. Much easier and cleaner.
The amazing thing is how little is actually wrong with these tv's. This is a wonderful channel to clarify exactly how you fixed these models. I can't wait to take another look into my bad tv because it could well be some very inexpensive part(s). Very helpful! I enjoy fixing stuff too.
Great clip! I was a TV repairman (old analog TV). Your video is really good, especially for techs, but I doubt an average person could do such repair (mostly due to the lack of tools and patience).
Thanks!
I did the same thing with my 3k, 10 yr flat screen by replacing four capacitors for $1 plus $4 in S&H 2 yrs ago. It was the first time my adult son got the chance to watch what his mother use to do for a living when he was a toddler. It impressed the hell out of him, lol !
thats pretty cool.
I garbage picked a gateway plasma going on 6 years ago (I fixed it on July 4th while I was off). Replaced $12 worth of capacitors on the power supply board and a sub sound board it has. Still working today.
That is awesome!
You're the man! I have a 60" TV in my basement right now waiting for me to replace some capacitors!
Keep us posted how it goes!

He needed to use his right hand to hold the transistor, and his left to hold the heat gun, he would be more stable using the hand he is more used to using for small parts.

Congratulations on the repair. It's a very rewarding feeling. Greetings from Arizona.
Thanks! Yes, this repair was a lot of fun.
The most important part you forget to mention, how did you find the wrong component? need to be tested all the components?
If you search online there are forum posts and even other videos that explain this transistor is a place to start your diagnosis. I didn't spend very long on the diagnosis since others had helped point it out. The internet is a great place to help solve problems.
Agree, this is just bs component troubleshooting, no instrument. Continuity is useless on on board/soldered component.
@@Sal112350 you are incorrect, sir... continuity is a great way to test... but, he failed to actually prove that the part was the issue. He should have tested the continuity on the board again AFTER the apart was taken out to show that the part was causing the short and not some other component on the board. THAT is the proper way to do a continuity check.
@Derp The answer to your question, Derp, is bad design. The transistor in the circuit is running "hot" (over 70% capacity) regularly and if the transistor quality is weak it will go again over time. But this knowledge has little barring on the propose of Frugal's presentation. He tested the part, it needed replacement, and he showed how to do it. If a person watching tests the part and it isn't shorted... they should find a different video to fix their problem :-) .
@Derp You sir, are correct. After doing this kind of work for around 40 years, knowing to check components on the secondary side (for the lack of a better term) of this transistor is a must. If another part is shorted, leaking, etc., it's pulling too much current through the transistor so it failed. Sometimes you get lucky. Lot's of times you don't. If that transistor popped, what does ''the internet'' say then?
OMG you a tech genius, u saved a tv that had the exact problem but different model my tv was model 43R6E3 and it worked! Thank you for the pointer as soon as I saw the video I knew we had the same problem.
Congrats on the repair!
Good job, thank you for teaching others this kind of skills.
Great how-to video. You explained it well enough so that I feel confident enough that I could do the repair on my own TV if need be. The link to Ali-express for the soldering iron and hot air combo was a nice touch because although it is cheap equipment, it would probably last long enough to make a few repairs and save me the cost of replacing the entire TV.
Thanks! I’ve been buying a lot more from AliExpress this past year and I’ve been happy so far.
Nice job on the video. Very clear photography. I really thought this would be a video about a bad capacitor. I have a ~15 year old LG 27" 1920x1200 monitor that I fixed many years ago. I learned what was wrong by searching the Internet forums. My search taught me about "capacitor plague." Ballooned cheap knockoff capacitors that caused many electronics to prematurely fail. I replaced the bad capacitor and my LG is still going strong today. I agree with you. The Internet is a wonderful resource for DIY'ers.
Thank you! Great to hear you fixed your monitor. Yes, so many tvs and monitors were hit by that "plague".
I fixed our Samsung a couple of years ago - replaced a couple of transistors on it. Great tutorial! Looks like you’re channel is doing great! Thanks for subscribing to mine. 👍
Awesome to see you've got a YT channel with some great content! Way to go fixing your tv too. Did you perhaps mean replacing capacitors?
FrugalRepair Right, capacitors. Thanks for that correction! Good to hear from you.
I don't bother fixing it just wait for exchange replacement program and get rip of it...
Hmm...you too can fix a flat screen TV for $0.54...if it happens to need this particular transistor, never mind how we diagnosed the failure, and you have a hot air rework station. I once saved a stereo receiver with a $1 capacitor, too, but that was the only lucky shot I’ve had. The other jobs took a lot of troubleshooting and had more involved failures.
he coulda fixed it with just a soldering iron. but I understand what you mean. my mate fixed a four-year-old 60inch telly using NO parts. (just squeezed up a screen connector). but I think it's worth having a look if you have a few tools and basic skills - if you can't fix it, there's nothing lost. if you can it's a result
I like your mood sir when u are repairing, your follower from the Philippines
Thanks!
Hi Fugal, thanks for the video. I suggest you adjust the air flow on your hot air gun as surrounding SMT components may be blown away, and you can notice that in the video when the diode above the transistor started sizzling, and if they don;t get blown away their soldering will dry out hence making it a dry joint. The trick is to use a good heat with less low air flow, that way the heat contact is precise on the bad component.
I agree. This is not my best work. I was excited plus I couldn’t really see what I was doing since my camera was so close and covering the board. I have a microscope camera now so that won’t happen again (hopefully).
I designed and installed my own 15,600W solar panel system on my house. It will be a new video series later this summer (after a few more videos like this one) Check out a sneak peak on my website: frugalrepair.com/solar/

Such a coincidence, a friend of mine was about to do that same, same exact model. Took it apart and pulled out the board. Did a multimeter test and the results were the same.

Cool! Thanks for letting us know.
@Enoch Pedersen I put the specs in the description so anyone can hunt down online for a good price/option. I'd would first check on aliexpress if you can wait for it to arrive from China. Otherwise, check with any of the US suppliers.
@@FrugalRepair i have the same tv model but the 70 inch .....e701i-a3 with the same exact problem. so this will work with the exact part u replaced with?
@@MrHontas83 The tcon board would be the same. You would need to either test the tcon board for other failures in addition to this transistor to make sure or you can replace the transistor and see if it worked. It is very possible that there are more bad components on the tcon and it is possible that your lcd is bad and thus not repairable. You can also simply buy another tcon board on ebay for like $17 and pop it in quick to see if it fixes the tv.
@@FrugalRepair where do I get the machine to test and what's it called
this is your bread and butter, how reg joe gonna know that transistor is the culprit?
How didnt you see the moment where he is measuring that very component.... It isnt that far fetched that understanding its inner workings it is much easier to go and look for failed components. Because they are most commen to fail just hard to find if you dunno what is controling what. Just grab yourself some broken tv a multimeter and go have some great fun. But remember to stay away from the high voltage area...,if you dont you find out really fast why. Good luck! Stay safe!
Most issues like this can be quickly checked with under $150 in tools, and a quick google search of " common problems". I have done this numerous times for all sorts of various electronics and it has saved me not only thousands of dollars in repairs, but hundreds of hours of manual troubleshooting.
Good instructions thanks. This might be the repair needed for one of my two Vizio's crashing in the same two weeks. I'll explain both situations and hopefully you can share your thoughts on diagnosis. TV. #1, Backlight certainly works but losing color, contrast and brightness as the picture is starting to blacken out in top left corner and bottom right...almost is rectangle shapes in each corner. Picture is good after a rested restart and the problem quickly creeps back in. TV. #2, our oldest Vizio maybe 8 years, 50". First sign of a problem was the quick App start brand bottoms at the bottom of the modern FireStick would change the TV input to an unused port. Next problem it would blackout and flicker back on with clear white horizontal lines. Then it flickered until it don't come back. After long rests it worked again a couple times, V logo came up, with sound, and was back out within 10 minutes. Now it's out-out with no sound of the FireStick clicks changing the Apps, no V logo and all black screen...no backlight. With was a 2 month fading experience from beginning to end.
Most solder has flux in it and also I would never use hot air station its risky and for repairing one thing its pointless.
Just use a soldering Iron it's cheap and it works well and its safe if you use it right.
My thoughts exactly.. For a 3 pin component it's useless. Just pump the solder from the board, put the transistor on place, and solder it with a simple iron..
@@freeeflyer Did you mean: suck the solder from the board...? I have a solder sucker...never heard about solder pumps... :)
@@bror8228 If you need to desolder lots of connections, you can buy a solder station fitted with a vacuum pump and nozzle.
Who needs a solder suction pump for a job like this? Just use solder wick. Should have cleaned off all that excess solder so the new part leads are in contact with PCB with minimum solder in between. That huge pile of solder this guy used is more likely to crack than if it were minimal.
Also soldering one leg to tack it in place with an iron is easy and then you only have to touch the other pads after you have cleaned and added new solder to the pads.
Yes, I fixed several LCDs just by replacing a visibly leaking capacitor!
It's repair 101... (1) look the board over with a magnifier, are there any burn marks (change the burnt stuff) are there any dry joins (reflow them) are there any board cracks or scratched traces (bridge the gaps with wire), are any caps leaking shit (change them) (2) Check voltages Mains, DC voltages at chips etc (3) test shorts/continuity on fuses (should be), transistors (shouldn't be), caps (shouldn't be) etc etc... most of it is common sense...
What were the symptoms your tv was showing was it not powering up by any chance.
There I no such as a visually leaking cap...wives tale extension there is no leak you can actually see in a leaking cap It just means the cap is leaking voltage not leaking a substance so...you have never fixed anything by finding a leaking component since there is nothing to leak out of it. b.s. called you shant recover back peddling not allowed it's just a bad lie but why did u lie there's a deeper reason me think
Lie no such thing as a visually LEAKING CAP there isn't anything TO LEAK OUT only voltage drops that what leaking means ya moron not like a substance leak so I gues you have x Ray vision I f you can see leaking voltage lol ....I hate b.s. liars
kirk watstien - you ain’t seen nothin’ yet if you haven’t seen a visibly leaky aluminum electrolytic capacitor. They have a discharge vent on the PCB end, and the leaked electrolyte is often visible on the board. And they will also pop their lid, which is quite visible. No BS to this, you just haven’t had enough experience with all sorts of varied devices to have seen those.
Thank you for this great info! I replaced the culprit mosfet with a random mosfet I desoldered from a random board. The tv turned on for a few minutes before blacking out again. This confirmed your suggestion that the mosfet is burnt. I can now go look for the correct spec mosfet to repair my tv. Tv is a SONY KDL-70R550. It’s an old dog but if it costs 50cents and a bit of sweat to repair I’m happy to continue using it.
That model uses the same tcon? Keep me posted.
FrugalRepair it’s using the 5348 board but the layout is identical. I’ll keep you updated with further developments
I couldn’t find the mosfet of the exact spec that you specified so I tried my luck with a SI5328DS mosfet rated for 100v. It works and the tv is back working
Fix the car
It’s the skill of finding that failed part that makes the repair bill, plus your soldering station, access to schematics, multimeter, etc.
schematics.... many of electronicians don't use schematics for fixing boards, we uses them 20-30 years ago, now theire not avaiable for the most of them. So, we tests, we try, and maybe we fix...

Wow, I'm honored! You made my day. Love your channel. Thank you!
Screen is tore half an inch not cracked can we fix it
You mean that there is a scratch in the screen? You probably can't fix it but you can minimize the damage a little bit. The part you touch on the lcd panel is the front polarizing film. That is glued on to the lcd with clear adhesive. Its been a while but depending on what kind of scratch and how deep, I've used a pencil eraser or a black permanent marker to mask some of the imperfections.
But now he end up with Vizio...... Not sure that a good thing...

Thanks! Did you happen to see the latest video? It was the cheapest repair yet to get a tv working again.
@@FrugalRepair I just watched it. It's amazing all of the tricks you have picked up repairing these TVs. I actually have a 50" Samsung Plasma TV that has one green vertical stripe. It started doing that at 1 year of age and I just quit using it. Since I never throw anything away, I still have it. I'll have to peruse your channel to see if I can look for pointers on repairing it. Of course, it was replaced with a 4K LED TV that blows it away, but it'd still be fun to repair it. I originally came to your channel to show a friend how to look for lightning damage to his TV. Thanks for putting out such useful content and taking the time to help so many. You're banking a lot of positive karma.
Thanks, that’s encouraging for me to hear! Lines on a plasma maybe a relatively easy fix. It is possible (but I don’t really know in your case) that the ribbon cable needs to be cleaned and/or re-seated. You need to have the tv unplugged then locate the ribbon that controls that section where the line is. I bet there are videos about it. Those ribbon cables are usually at the bottom after you take off the back cover. Usually they are connected to the Z-board. You can google that.
Newer TVs are easy to fix now even if you do not want to change a transistor you can buy the boards cheaper than buying a new TV and just replace the board. I have fixed a few TVs over the years. The old tube TVs were easy you just pulled the tube out, took it to Radio Shack and got a new tube and replaced it lol.
Exactly. Swapping out boards is pretty easy and you only really need a screwdriver.
No doubt the TV repair chains lobbied for tv's with no tubes so you'd have to pay a technician an outrageous fee to replace a 5 dollar circuit board. I remember fixing my own TV many years ago by testing for those burned out tubes. Cars were owner repairable also.

@@BB-ce3bj making he looked in an online forum where someone had the same problem
Wilcon Barro Yes. As with most repair jobs of any type, you will need tools. They probably cost a lot less than the repair shop or the price of a new TV though.
Multi meter is like 20 bucks at Walmart.
Soldering iron 10-15
Flux 3-4 bucks or free with soldering iron

Hot air shit not necessary and most likely you'll damage something else if you don't know what your doing not worth the risk
Les then 40 and you'll have useful tools in the future just in case.
I just picked up a vizio 47" tv for free the seller described it as the backlight went out on the right side, so I brought it home (this is my 5th tv I've fixed from my crona quarantine away from school for the past months thanks to you! Btw lol)well I decided to plug it in to see if they where correct and all the sudden I hear it squeal and smoke comes out of it!!😂 well I take it apart and look at the backlight inverter on both sides sure enough the right side was burnt from the capasitors smoke and the left side capasitors where bulging so I ordered 5 new ones I only need 4 but why not have extra lol for $6.99 and now it's running perfectly strong and has been for a week. Sorry for the long read but I figured I'd put my story if it might inspire someone to get after there broken tv and fix them.
That’s so great to hear!
If you prepare the lands as you did, plenty of flux and use a soldering iron to make each land. DON'T use hot air to place the new component in!
Right. This was almost like a "how not to" video for SMT soldering. I was cringing the whole time.
Any problem with hot Air? I mean some do solder set with hot air right any reason to avoid it?
Jon C. - unnecessary for this particular component with three leads. If it was a chip with lots of leads, then a soldering iron won’t be the tool to use.
Smartass guy... 0.54 cents for a transistor, 2 hundred bucks for the tools... knowledge, practical work and warranty are priceless...

I repaired my 10 year old $2400 Samsung LCD for $3.50 by replacing 2 bad capacitors on the power supply
I find that the longer I live, the more capacitors I have to replace!
Yeah i had a pretty similar case once, where i just had to replace one cap.
Kinda funny how easy it is *some times*
Samsung TV's from 8-10 years ago were notorious for a bad batch of electrolytic capacitors. The company did a great job of repairing as many TV's as possible within a reasonable warranty period but you can only do so much. I repaired one 2 years ago that was out of warranty, for a friend. Capacitor kit was $12, shipping was $8. I volunteered my time(less than 2 hours) For $20 she had a functional 46" TV. Still works great today.
I did the exact same thing! Always check to see if what ever you have has a fixable problem.
Great job fixing it!
Can you help me fix my flux capacitor I’m stuck in 2018 need to get back to 2055 😁

why do you not use something like capton tape to shield the other components from the hot air?
Hope you please will teach me, so I better understand.
I hadn't thought about bending coper wire on a thicker soldering iron tip. That is a neat suggestion if you don't already have one with a fine tip. It still might be hard to solder in a small component in a tight spot with that setup. I'll have to try it sometime. I didn't feel the need to add kapton tape since the nozzle is small enough and the hot air can be directed to the one component. It depends on what work you are doing though. When working on an iphone board, for example, I may use kapton tape and place a metal coin nearby to help absorb some of the extra heat.
@@FrugalRepair Thank you for your great answer. About the copper wire, I find a thickness that I seems to fit the task and then start to bend it until it sits nice around the chip and let the tweezers and heat do the rest:-)
Also wary nice and hard to reach places, like under a capacitor, in the corner near some plastic. You can always put an insulating tube around the 4 inch long copper, if necessary. :-)
Your explanation about the heat gun, do make a lot of sense, I do just not have enough confidence and knowledge yet to dare that. It takes a bit of knowledge as you clearly have!:-)
Hi, i just want to thank your video, mate. I repaired a Sony 60'' with the same symptom. But in addition in my situation, i had to cut the left cof tabs. The MOSFET used in my case was the Si2308BDS.
Way too much flux. But good job fixing it!
The bigger the glob, the better the job - Louis Rossman - 2017
You didn’t clean the flux residue off. At least wipe the area with a flux cleaner pen as a final step.
Seems somehow you forgot the word "Repair" from your title.
It’s in the thumbnail
But not in the title.
@@fleximo3734 Not required on the title , he got it for free then had to spend 54 cent.. so yes its a 60'' Vizio he got for 54 cent ( .. plus his own work time )
@@yanz1232 Title is simply missleading because it says he got a 60" tv for less then a dollar when actually he bought a component to fix/repair it. Yes he got the TV for free and cost him less then a dollar to fix it.
Brickbait...
As an EE, I salute you for the knowledge of an appliance, plus the incredibly small working parameters. I've never thought of using a heat gun in lieu of an iron, however small.
Thanks! I studied computer engineering, all those EE classes have definitely helped me understand what components are and what they do.
@@FrugalRepair so when the screen is black it's most likely the T.comm board and not the main board,I'm asking for a friend. .....
Question is how did you know out of all those components that one transistor was bad? Did you test all the components on the display board or something?
He literally explained that this was just a suspicion before testing. Many repairmen work like this. You don't have the time to check everything so you just move down a list of parts that have a high likelihood of failing. If this TV is known for a particular part failing then why even bother with the other parts?
He watched another UA-cam video on this common issue..
Touch a 300v capacitor and it'll enlighten you to the dangers of home TV repair.
That being said its a miracle my heart hasn't exploded over the years.
I mean... we got taught that if we ever wanted to open anything with big capacitors we should wear protective gloves and prioritize discharging of the capacitor.
Yeah, but not as bad as touching the high voltage contact on a CRT ... I’ve seen that knock someone flat on their back side...
Impressive. Especially the Visio mind meld when it told you which part was hurt.
Ha ha! That’s called UA-cam.
It was painful to watch you trying to work with those tweezers lol
I would be the same way. That is a small transistor. I get the shakes when soldering small stuff also. :(
yeah i cant bear to watch him using those tweezer
Same feeling
Oh the perfect people can't stand it. Must be nice to be so flawless. Douchebags.
@@X934YZK, No one is claiming perfection. It's simply about avoiding damage to the board. Rocking a component like that before the solder reaches it's melting point, can rip the pad right off the board.
Definitely not a fun situation to deal with.
Oh,, your tv is dreaming inside a dream..😱😱
I have a 60 inch LG plasma that needs a similar repair. But I’m so scared To break it even more and I’ve never seen the tools you’re using before in my life other than just a basic solder gun. The TV is 600 W to run but it’s bright as the sun and crisp as a rainbow. I repaired it once by replacing the motherboard but accidentally gouged a little piece of solder.. stopping it from Booting up all together. I’m very confident that your technique will allow me to repair this incredible plasma. Just need to know more about the tools to get me there
Well but if you don’t know where to look, its an awfull amount of transistors and capacitors to test.
Oh man! I could beat this guy at a game of Operation!
Heck yeah!
HAHAHAHAHAHA!!!
Typical in any sort of repairs, the part is cheap, but the knowledge and know how, takes years.
And it appears, very steady hands, and the tools to do the job.
Nicely done.
While I was younger, and better eyesight, I may have been tempted to try a repair.
These day, I’d throw it out and buy a new set. Or if I were lucky, find someone with your skills and pay for your talent.
Thanks for your comment. Actually with the internet diagnosing a board that has a common failure doesn’t have to take very long. It is because other people find the faults and share the info online. Those issues that no one has come across before (or posted about) are ones that can take a bunch of time to track down the culprit(s).
Good job, since it costs you .54 I can pay you 1.08 plus shipping if you send it to me. That's a whopping 100% margin.
nope, that's 50% margin.
@XBOXRULES that's 100% markup, 50% margin
@XBOXRULES Why are you talking to me I am a failure at math.
@XBOXRULES Just because you are too lazy to google how to calculate a margin rate should not be an excuse to be so pedantic.
@XBOXRULES Lol dumbass it's a 50% margin.
Impressive, but how did you diagnose it was that actual transistor? There was a lot of stuff on that board.
Testing multiple things, then put back together, then make video.
Or.... research issue on model and see it is very common failure, then make video hoping it works ..
Probably read up on it on a repair forum online ...
Oh, he answered that same question in another comment - watched a different UA-cam video!
Thats amazing, my brother did this to his TV and got it to work just fine, thank you for the video and pointing people in the right Direction!
That’s great to hear!
“You need really steady hands for this.”
Damn. Count me out. 😀
That's GREAT! I have to same problem, just one question, WHAT IS THE PART NO, SPECS, HOW DO I GET ONE?!
No longer apprehensive about purchasing a Vizio again. Thanks.
You probably can't know ahead of time who makes the TV until you open it up. Vizio doesn't make the TV's actually. Usually the manufacturer is LG, AU Optronics, or even FoxConn (who makes iphones). I've even seen the same exact vizio model made by different manufacturers.
Lol, good video. Only a 50cent replacement part and a 200$ hot air machine.
the jokes on u, u can do it with $5 soldering iron and $1 flux too
@Joshua I agree with you. The tools this guy used to test and assemble, definitely cost more than a few cents, lol 😂
How did you determine which transistor to get?
model number on the trans maybe ?
It was probably a common issue with this set.
@RS2002 He checked online for people with the same issues as his TV.
He said in another comment that he watched it on a different UA-cam video!
Just found your channel, the issue with my vizio is all the input ports stopped working so we cant plug anything into it. Lots of great stuff on your channel, I also try to help people save money by fixing thigs. Thanks for sharing.
i fixed my broken tv by throwing it off the window
it worked just as intended
forgot to tell that you put _i dunno how many years of study_ your knowledge under 1$ price.
but well done.
Thanks. I think you give me too much credit though. I don't think soldering in one component takes years of study and knowledge.
@@FrugalRepair :) ty. Maybe not many years but you have a background to do this. I understood the real meaning if this vídeo. I didnt meant to be rude...
@@fshimage No problem, thanks for your comments.
@@FrugalRepair at all. Actually I think using a heat gun was the hardest part. For one component with three leads you could of even used just solder and a soldering iron and popped one lead or leg at a time. But doesn't matter the job got done and the set now works.
That part was big enough not to use hot air, but if you do, solder paste works much better than wire. Melts more evenly and you don't have to keep tweezers on it. It also might help if that board had some heat sinking. Thanks for the video!
Thanks! Great idea.
Wish I could like twice.
create a second account you lazy sob
Most parts cost pennys its not some miracle here .the rest price for repairs comes with cost of tools, experience ,knowledge , rent ,workers ,vat
And many other things.most people will break fixing.please at least tell people with risks opening TV by getting shocked etc.To me this video informative because i do fix stuff.for other canbe last thing they touch 🙌
Im having the same problem . You did a great job. I will try to fix minds like the way you did. Thanks god bless
Thanks! I hope you can fix yours. You can also just try replacing the tcon board.
Ok thanks I'll my husband know
@@haydeepoll927 Just realized I wrote "can't" instead of "can". Tcon boards are fairly inexpensive so that may be a better way to go. ebay usually has lots of them.
i get the hot air for removing, why not just solder the part in?
no. and yes.
So he can show you how Shakey he gets under stress
@@lexander9686 what have you done troll?
it would be interesting to show the diagnostic procedure and not just replacing a transistor, everybody can replace a transistor. testing the transistor on circuit is useless, more than often there is dc path around them by resistors and other components or even some other shorted component can create a dc path around the transistor.
also that transistor is shorted but if it was open like often happens the beep or continuity test would be useless, it doesnt beep so in your line of thought it is good. try to go a little more in depth next time please. if somebody is uneducated in electronics hthey will learn nothing from this video and if the person has electronic knowledgde they will learn nothing either
I don't know if I would agree that "everybody" can replace a transistor. I understand you may want more in-depth board level diagnostic explanation but that isn't really the point of why I made this video. One of the big points of this video is to inspire people that things can be repaired inexpensively and I give an example of how it can be done on a tv that would otherwise be thrown away. If you happen to have the same t-con board and it failed, at least I've helped you with a starting point in your diagnosis and repair. And yes, there could be other damaged components but in this case, it was the only issue (like in many cases) and the tv was repaired.
Hey, here's an idea. Why don't you set up your own channel and do it yourself?
Sheesh.
he did with a multimeter lol
@Prottoy Nahian nearly all youtubers list the products they use in the description. He didn't make a big deal about any of the products, not at all dishonest.
Hugo... other way around. Maybe 1 in 10 of my 1990s computer engineering class could solder and almost none of use would solder surface mount parts on an existing board. I spent four years on design and assembly involving such hands on work and I never got good enough to solder surface mount components. I would have attached wires to the transistor and soldered the wires on -- rather than try surface mounting such a tiny component by hand.
Anyone with the skill to solder surface mount parts by hand can trouble shoot a board -- they are either in repair or assembly work with the later trouble shooting their own work.
Nor is it a terrible interesting video to look where the video power on/of line in coming in and then track its path and touch both ends with a multi-meter.
I enjoyed watching this video, especially the soldering works for the new transistor. It s like watching man landing on the moon.
Than you for the encouragement! I think I did a better job explaining the soldering process on the 65” 4K TV video. Did you get a chance to check that one out?

Dude have you lost your mind
heart surgery has also only 2 $ materials cost , but you pay 300.000 $ for it.
This is wrong way to put things into perspective. it's never about the material cost but the skills.
I see your point but I would argue this is different. You don't need to repair your tv, you can buy a new one at the store. But if yours is broken and you are going to throw it away anyway, then why not give it a go and try to fix it yourself? In the case of this tv, you can literally buy a new tcon board on ebay for $17 and put it in very fast. What I am showing is that you can do even better than that if you wanted to try. And you don't need expensive tools, buy a cheap soldering iron or hot air station and watch a few videos to educate yourself.
I agree with you. You and me can do that.
But the title "for less then 1$" degrades the value of our work implying to others that our work is cheap.
e.g. here is true story : there was a TV repair shop in my city, after his TV was repaired customer asked what was wrong with his TV, and the owner said, it was a resistor. Then customer left and actually brought the new resistor to the owner, and said here is it.
It is dangerous to reduce the work to the cost of spare parts, leaving out the practice and eduction of decades, because the most people don't get it.
replacing those logic board still cost less than buying new tv...the expensive part is actually the LCD which i can assure you if your LCD is broken it could cost almost the same to buying new TV...maybe more than 80% of the cost from buying new TV...while replacing new logic board maybe cost like 10-20% of new TV...but if you have the skill repairing the logic board sure cost less...but if you dont have the skill replacing logic board is easy and should not use much of skill..so even if you send to repairman they should charge less if only replacing the logic board...
@@stewiegriffin6503 All your story does is reaffirm that most customers are morons
@Fanta I would go even further an say most humans are morons.
Superb fix - So many flat screens being thrown away nowadays simply because of faults/issues like these which can ultimately be repaired with knowledge.
Yes, it happens all the time. Usually it is a fairly simple fix. In this particular model you don't even need to go to the component level like I did. You can easily buy a new tcon on ebay for like $20 and with a screwdriver replace it.
@@FrugalRepair I worry about such purchases what if someone sells a bad board?
@@dannygjk It's usually not a problem, just send it back for a refund. Even ebay sellers who have a "no return" policy will almost always (since they care about their rating) will take things back.
"Only $0.54!!"
> using $500 rework station.
That transistor could have easily been replaced with a 10$ soldering iron, given that it wasn't connected to a large plane with high thermal mass.
coulda done it with just the soldering iron...…….
...and $50,000 for the college education to learn HOW to find the problem component(s).
The part could have been replaced, and probably far more accurately, by a $10 pencil iron.
@@alphabeets Of course, because you definitely need an expensive college course to learn things nowadays when the internet is so widespread.
I pickup tv,s like this all the time and fix for pennies.
Thanks for sharing, in this day and time we need to change our way of thinking. With the pandemic that has arrived there's going to be a point where there will be issues of being able to afford the luxury items that we have been accustomed to buying. We are definitely going to need to repair what we once threw away, or the option will be to do without. If one thinks that the Great Depression was only a thing of the past, you're in for a surprise. You've earned a new subscriber.
Thanks! Great perspective.
Apple prohibited you to repair your own thing.
Even, blocked you from the forum.
Oh they certainly flagged the video as p0rn as well.
Wow 54 cents?
Minus the $200 hot air station
The $60 soldering iron
The $10 flux
You dont just wake up one day with all the tools and knowledge of a skilled trade...!? Wtf We should complain to the government about this discrimination against ignorence.
Soldering irons are cheap though
store.rossmanngroup.com/index.php/quick-861dw.html! Less than $300
And still cheaper than buying a new 60", plus those tools can be used over and over to save even more money.
But most folks go for the convenience of replacing today's flood of crap quality products.
But manufacturers know this about human nature, hence the intentional crap quality.
Convenience saves time, but costs you far more than you realise over the long term.
And the electricity
You do not need a hot air station. Just use some chip quick and tin all the pads and slide off the old transistor. Then make sure to wick the rest of it off then solder the new one. Both methods work.
My 60 inch is working just fine, but after seen this video im just gonna open it for the hell of it and see what i can FCK UP so then i can fix it. LOL 😜😜😜😜😜😜😜🤪🤪🤪🤪🤪🤪🤪🤪🤪
you're parents are gonna beat the shit outta you
The most interesting part is missing : your investigation and all the tests you did to conclude it was this component.
It was probably a common issue with the tv
I really like your channel personally .... You provide very good content...
Yeah, 54 cents part but $8 shipping and handling. ;)
Not really, you can a lot of stuff shipped for free from aliexpress.
