As a Certified Electronic Technician I applaud your easily understood instructions for the layman or novice technician. Keep up the informative videos, Bro.
So Tampa tec Dude, basically after getting laid off my job I created my own employment by grabbing tv monitors and computers from the local recycle bin, fixing them and reselling. Recently I found an LG 55UF6450 4k smart tv and it powered up but had a blank screen. Following your recommendations I checked the capacitors on the power board and they were all good so I took advice from another dude on you tube and tried baking the mother board in the oven for 10 minutes at 385 F. well it worked and now we have an awesome tv cost us nothing. It always amazes me as to what people throw away. Im not an electronicas guy but with your help I would say that I am becoming one. Thanks so much for your guidance and easy to follow instructions in your videos. Keep up the great work. Kudos to you Dude!!!!!!
I remember my dad teaching me to fix TV's in the mid 1970's when you could pull a vacuum tube and take it down to Radio Shack/Tandy and test it for free on their tester. And they carried the tubes in house. Usually Sylvania (rebranded RCA) in a Radio Shack box. Simplicity.
Just a useful tip I've learned over the years: for those who may not have much experience with small parts or electronics soldering.. use a small tip on the iron and make sure it's plenty hot. It should melt the solder immediately. I always leave a tiny drop on the tip before going to the board. Get the suction bellows right down there and release the plunger as soon as the joint goes shiny. DO NOT LINGER ON THE CIRCUIT CARD OR COMPONENT!!! You can quickly burn traces and neighboring components. You may want to practice the technique a few times on some junk cards if available. Just some thoughts. Take em or leave em.
Thanks very much. This is one of the most informative, rational, sensible, concise, and useful how-to videos I've seen on UA-cam. Nicely produced, too, without a lot of nonsense and repetition.
Thanks for your endeavor. I agree with so many of your other commenters, that most of our electronics can be easily fixed for next to no cost. Your UA-cam endeavor is fulfilling to see how repairing instead of replacing is making a come-back!
First of all great video. I am a retired E&I tech from heavy industry, paper mill to be exact. Please remove all rings etc. before working on electronics as the potential for painful injury and equipment damage is present if you have conductive things on your hands,don't ask me how I know.It only takes a second to remove them and be safe.Its not something you normally think could cause a problem but the potential is there.
It is very informative. My Philips smart tv the sound is working when on the tv but after about 5 to 10 minutes the sound stops what could be the problem?
@@TampaTec I can tell you're not very smart.I 'd let an actual professional repair mine before even thinking about doing this.not some pretender like you.who thinks he knows everything
I had similar problem with my LG TV; a capacitor had blown on the power supply board. It would have cost around £35 for a replacement board and another £80 if I had an engineer to replace it for me. Instead I bought a capacitor from a local.electronic supply store £0.42 and replaced it myself. TV now working fine. £115 vs £0.42!!! Thank goodness for some basic electronic know-how and some common sense!
Wonder if you could advice me.. . My T.V has the standby light, if you press the buttons on the side to wake it up, I hear a kind off click sound.. like it half arsed wants to power up. I literally stood there for over half an hour before trying to get it to power up, which it does eventually! But prior to purchasing a part, this is what I have to do... Just not sure what part I will need?
@@jaeda88 just look up make /model/ serial of your tv. open up the back (in hopes of label on circuit boards) or inked onto the board for identification and replace.
Too bad we live in a world where it's so easy to just discard our things. It's great to see that there are still some people that believe in saving things that can be repaired instead of just throwing the item away and buying new.
Stephen Cox stupidest thing I ever heard you need screws and parts you cant get from a store which should be less than $50 and cost 1-4 hrs of work depending and saving you more than 200+ dollars
Stephen Cox Surely youre not going to try and fix a cheap $300 TV. But a $1000+ tv, im sure people would rather spend some money formrepairs instead getting a new $1000+ TV.
Yeah, I completely agree. Makes me feel a bit guilty too. Just last week, we took my grandmother to the E.R. with chest pains. The doc told us it would run approximately $35k to insert an arterial stint. Luckily, they had a refurbished grandmother, that was a few years younger, for just $7k and a 6 month warranty. Sure ... we're going to miss our real grandmother ... but then; "Nobody pays retail prices anymore. Why should you?"
TY so much. I had my TV plugged in for over a year but never turned it on. I'm guessing it surged during a storm or 2 we had this year. Very easy fix thanks to your video! New Sub
Great job, I have been repairing crt's for 25 years, now they are mostly gone. I am retired but fix the occasional led tv for people. Your tips are very good but most people are unable to use hand tools much less understand a voltmeter. I am going to repair a backlight problem on an LG tv for the first time. I told my buddy this is like open heart surgery. One mistake and the patient is done. Great fun for me!
Yeah, i scored a 50" lg that i had to replace 2 leds to get the backlight working. On refitting the diffusers and screen, something was slightly out of place so when screwing the bezel on i heard a click and realised i broke the screen. Now only the backlight works but I'll keep it for parts. Lucky it was free but I'm still kicking myself!
Cheaply made capacitors are the curse of modern equipment , and the horrible solder used nowadays . Lead solder is best but don't forget it can be absorbed through the skin when handled , gloves prevent this if you use it a lot. Always nice to see people repairing things instead of throwing them away !.

Solder made from 63% Tin, 37% lead is the best because the temperature between liquid and solid is just a point at 361 degrees. This helps prevent "cold" solder joints. I have been using tin/lead solder since I was 10 years old. I am 72 now and no ill effects. Of course you should have good ventilation, but unless you are eating the solder, there is little to worry about.

I have been trying to fix my 72 in flat screen for years. finding a repair place in kansas has been a challenge. it blew when somebody was repairing on outlit in the house. this video def showed me how im fixing it today ty so so much.
I agree with your repair method. I've repaired many LCD monitors using this very same method and I always try to get a high voltage cap to replace the defective ones. You might point out to your viewers that sometimes those caps (capacitors) will blow out the bottom (where it connects to the circuit board) and will not appear to be blown or domed. I've seen this issue on many power supplies. I've subscribed and will be following your work.
billfromelma thanks. so far it's growing more than I imagined. youtube is a blessing. just to think UA-cam was created because of Janet Jackson Superbowl boob slip.
I did same thing to my 10 yr old samsung. upped the volts on cap from 25 to 35 also. works great. these tvs really need cooling fan cause it gets hot due to flourescent lighting, maybe its made that way to fail prematurely and sell more tvs? great video, keep them coming.
Thank you for this helpful, easy to follow video! 🤩 My TV has the issue of the red standby light but not powering on. Unplugging to reset it was working as needed for a few months, but the frequency needed for that continually increased until yesterday it seems to have given out for good. I'm going to try replacing the power supply board -If I remember, I'll update here how that works out for me! 🌟
Great videos. I'm also a repair tech and you have very instructive tips. I just discovered your channel and already subscribed. Thanks for being so clearly open. Big thumps up all the time!
this video helped me to fix my grandads led tv it wasnt turning on one day so i orderes a new power supply for £20 fitted it and its working perfectly and then he bought me a 2ds as a thankyou
I had found a 47LD450 by the side of the street that had been thrown out. It only showed the red light, no picture and I couldn't get sound either. I followed your advice about checking the voltage on the pins from the power board to the main board, and it showed 3.35v on pins that should have been 3.5v and 0v on the rest (some were supposed to be as high as 20v). I ordered a power board and I will update this post when I install it. Thanks for posting this video.
Problem spotted at right about 2:31, we have a few condensators (capacitors*) that have inflated, I would bet that those are on the 12v rail. And I agree with most comments, based on my personal experience, 9 times out of 10 its the capacitors.
What were you're symptoms that led you to replace those parts. I have a screen that is showing half black screen and half a lot up screen. Backlight is good
The last television I repaired, I rinsed out with Dawn dishwashing liquid and a hot garden hose. I gave it a good wash out let it dry a week it's been running ever since about 8 years ago. The detergent did a better job than air blast on the affected high impedance circuits.
Great video, good job. I do have something to add that may be helpful. When sourcing new capacitors it is always a good idea to increase the voltage handling capacity but be sure the dimensions are the same or close enough. Even more important, especially if the faulty caps are swollen, is the temperature rating. It is likely the caps that failed are rated for 85C and for a little more money you can get 105C or above rated caps. These will last much longer and with the money you're saving why not make your repair last? Also, electrolytic caps dry out over time and are a big failure item. It's a good idea while you are in there to replace all the large caps if you can afford it. (the small caps are usually safe to leave in as they are mostly signal handling or dc blocking components and see much less stress) Keep up the good work! Bat
Good information. I had pulled the back on a donated 40" and had visually identified two swollen caps, but decided to replace them all...and it worked. I got lucky
I just gotter say........... there seems to be alot of people slagging this man off. My point is, , when you all quoting how long you been doing this and that and mocking this man................. i say "fcuk off" and do your own channel........ this man is trying to help people that maybe cant afford to run to people(maybe like you'all) to fix these kind of tv probs. for those guys i say ( as we do in England" JOG ON!!
Mikail Okewole, if you're doing laptop component replacement? then due to their small size I've often used a 'Solder Paste' which is a fluid you simply squeeze through a syringe and it becomes conductive after drying - it beat getting a clumsy hot soldering iron into those tight spots.
Very informative, and makes me want to watch more videos! I have an old tv on hand with the same problem; I was about to give up and toss it, but now I think I'll open that puppy up and see what I can do. First though, I'm going to have a look at your other videos to see what else I can learn from you. I know it's not a new video, but you have a new subscriber. Good work.
That's what they want you to think. That is also why they installed 25v capacitors in there, they will expire more quickly in my experience. I've done this repair on many monitors myself, and i always install a higher voltage, and i have yet to replace a capacitor ive installed.
Began working on this and opened it all up. Unfortunately I have a fairly obscure Blaupuntk tv and the only matching Main Board is going for £45 on eBay :/ But the video was really neat and I'm glad it's helping other people
As a fellow Tampa-area resident ... thank YOU for sharing & creating content that has grown my understanding! I am currently working on a SHARP 70 (LC-70LE755U). The screen works - - but - - has a "wavy" picture. I have individually replaced TCon + PowerSupply +IO board (testing image after each install). Unfortunately, zero change from original screen fault. Those are the only boards ... minus some edge lighting + wifi card. I presume the LCD screen is not damaged ... since the lines are not fixed. At this point, I dont know what else I can do to repair ... besides maybe stripping down the chassis & replacing the LCD panel - - as a "long-shot"
Very good work. I have been repairing electronics since the 1960's with electron tubes and later transistors and later microprocessors and very often when troubleshooting begin with the power supply.
I had this same issue a few years ago. I checked out a similar UA-cam repair video. I had one capacitor that had swollen and blown a hole thorough it. Cost 50p to replace. Soldered in. TV worked and is still working.
At 2:30, the first thing I spotted was the bulging tops of the electrolytic capacitors. Capacitoris Bulgitis is a firm indicator for a transplant operation. :) I had 2 x "Bauhn" brand (from Aldi) TVs which both failed in exactly the same way as the TV you're repairing (red LED and clicking when you try to turn it on) and when I opened up each, I immediately spotted the bulging caps so I replaced them and now I have 2 working TVs. :) There's been a rash of electrolytic capacitor failures recently (over the past 10 years or so) and now they're always my first suspect.
I've replaced the capacitors on a computer monitor and a 46" Samsung. The monitor I had owned and the 46" Samsung I found in the street. Another 46" Samsung I bought at a Garage Sale for $5.00 and all that was wrong was a loose ribbon cable. Then I was given a 52" Samsung with horizontal lines that come and go. Sometimes I would take an HDMI out and back in and other times there were no lines or the lines just went away after five minutes. The total cost for 3 remotes, 3 TVs, and capacitors is about $25.00.
Harjan Mal Sir very helpful nice way of sharing n teaching, thanks TampaTec good instructions, really enjoy ur teaching, Highly appreciate, A Big ThgumbUp
Yesterday I managed to fix an old LG tv the same way.The tv would power on but it wouldn't produce any sound.turns out the 6volt rail was showing only 3 volts,and the reason was four swollen capacitors!
A myth about leaded solder - there are NO lead fumes coming off it. The fumes are the flux. These fumes aren't good for you either, but lead has a boiling point of 1749 °C - your soldering iron will probably be at less than 350°C so there will be no lead fumes. The lead WILL come off on your hands so hand washing IS important. To avoid the flux fumes, you can use a small fan (e.g. a spare 2 - 3" fan you recovered from something with a wall wart PSU). Don't use a large fan as that will cool your soldering iron tip off. In industry we commonly use vacuum fume extractors (expensive), but we are dealing with OSHA and people who may be doing hand soldering all day (e.g. rework operators).
I like how you get right into it instead of introducing us to your family, pets & extensive network of amazing friends & their hobbies..blah-blah. Info videos should inform & you get it.
@Tampa Tec Thanks very much for the help! I'll probably attempt this, now that I cannot find a new power supply replacement board anywhere, and even used boards are rare. It did look like some of your capacitors had "non-flat" tops (the Xs are carved in the top in order to give way when the insides boil and give a visible sign of cap failure). Reminder: Voltage is an "across" variable. Current is a "through" variable. Voltage appears "across" two points. Current "flows" from one point to another. Voltage can appear across a pair of points without any current flowing. Current can be flowing between a pair of points with no voltage across them.
I just did a DVD with a bad filter cap, I was actually looking for it since the menu screen was showing a faint 60 cycle hum before it died. I did TV repair in the 80s when transistors were beginning to dominate, it was all component level test and repair, here I am 63 years old and still playing with this stuff, too much fun.
I was told by a Samsung Engineer after telling him that I trouble shoot byYou Tube videos and that you can fix a TV by looking at Tampatec on You TubeTV.
One video I watched said sometimes cheap knock offs are installed that aren't rated what the capacitor states. Therefore it pops. His video was exact same replacement. Fyi. Peace
Nice work, did this with old plasma TV and it worked for about 3 months and then went out again. Went out and bought a Samsung smart TV after that. the Samsung went out about 8 years later. Sent the board to this repair shop in California and they repaired the board and sent in back in a few days. It is still going strong 2 years later. It cost me $75, so it was well worth it.
Great video, I love how you don't go on and on about unnecessary things! You get to the point, offer tips & tricks and get the job done! Most people keep this knowledge to themselves; they hoard it, use it, over-price their labor cost to do the repair and try to do the get rich quick scheme. I love that you share your knowledge and seem to share the principle “If you give a man a fish, you feed him for a day. If you teach a man to fish, you feed him for a lifetime.” Very impressive!
Great vid Tampatec, I'm very much like you, fix tv's when they can be fixed easily. Now, newer tv's all have cracked LCD/ LED problems (for the most part) which is a costly repair and not worth fixing anymore. I'm curious if there's a way to salvage the working half or portion of those screens and port a rasbery pi or arduino to throw something up to at least make some use of them..
Tampatec I have had the same plazma tv for 5 years. I got a great deal on it because they were going led on all of them. I was told this one was the longest lasting best Plazma tv out there. I guess the guy was right. Its an LG. The salesman said it was a shame they were getting away from plazma because mine was the way they should have all been made.Once its done,its done. I will be hunting for an Led style that needs repair as a back up. I am really handy at electronics and testing so It would be fun fixing a dead one.
I have a sony bravia 32" lcd. It stopped responding. No buttons work, the remote doesn't work but when its plugged in it comes on. Its stuck on one channel. Any ideas?
a rough guess is that its the tuner control and software control pcb, the part can differ depending on what world region you are in, unless your a tech its not something you can fix (ive 30yrs experience and just swap them out because my labour would cost the customer far more,) but they arnt cheap so unless the tv is quite new (which at 32inch it prob isnt), id say its BER (beyond economic repair) sorry bud :(
Needed to understand how tor repair a tv i got from my brother as it randomly stopped working now i know what to look out for! Thank you, lets see if its an easy fix

I agree with your repair method. I've repaired many LCD monitors using this very same method and I always try to get a high voltage cap to replace the defective ones.
You might point out to your viewers that sometimes those caps (capacitors) will blow out the bottom (where it connects to the circuit board) and will not appear to be blown or domed. I've seen this issue on many power supplies. I've subscribed and will be following your work.
I was a TV tech back in the 70's and 80's, the days of CRT and tubes. Now learning my way around these modern tvs. Very informative video. Thanks.
Great video. Informative, to the point and no BS. A lot of people could learn from your style.
Tampatec: simply, thank you for what you do and offer those DIY folks still these days!
great that ur fixing all these TVs and keeping all this plastic out of the land fill!
You do great stuff on this channel. I hope it grows beyond your wildest expections. Your awesome young man.
billfromelma thanks. so far it's growing more than I imagined. youtube is a blessing. just to think UA-cam was created because of Janet Jackson Superbowl boob slip.
I didn't know that. It sure has escalated in quality since then.
billfromelma grammar not even once.
Thank you for your videos they are all very informative & easy to understand I've enjoyed every video I've watched

Dude, you just saved me a couple grand! You're awesome.
I bet u had a smashing time didn't you
Helpful
I cam save you a couple of grand....
Don't pay over $600 for a TV
@@JETJOOBOY Or take care of your TV lol.
Than you. Great teaching brother. Beginners like me can learn a lot from your videos. Appreciate it so much.
I did same thing to my 10 yr old samsung. upped the volts on cap from 25 to 35 also. works great. these tvs really need cooling fan cause it gets hot due to flourescent lighting, maybe its made that way to fail prematurely and sell more tvs? great video, keep them coming.
Thank you for this helpful, easy to follow video! 🤩
My TV has the issue of the red standby light but not powering on. Unplugging to reset it was working as needed for a few months, but the frequency needed for that continually increased until yesterday it seems to have given out for good. I'm going to try replacing the power supply board -If I remember, I'll update here how that works out for me! 🌟
Great videos. I'm also a repair tech and you have very instructive tips. I just discovered your channel and already subscribed. Thanks for being so clearly open.
Big thumps up all the time!
this video helped me to fix my grandads led tv it wasnt turning on one day so i orderes a new power supply for £20 fitted it and its working perfectly and then he bought me a 2ds as a thankyou
I had found a 47LD450 by the side of the street that had been thrown out. It only showed the red light, no picture and I couldn't get sound either. I followed your advice about checking the voltage on the pins from the power board to the main board, and it showed 3.35v on pins that should have been 3.5v and 0v on the rest (some were supposed to be as high as 20v). I ordered a power board and I will update this post when I install it. Thanks for posting this video.
Problem spotted at right about 2:31, we have a few condensators (capacitors*) that have inflated, I would bet that those are on the 12v rail. And I agree with most comments, based on my personal experience, 9 times out of 10 its the capacitors.
Great Video, between you and another guy, helped me pin point the issue, had faulty Y board and mains board, replaced, now up and running, cheers
What were you're symptoms that led you to replace those parts. I have a screen that is showing half black screen and half a lot up screen. Backlight is good
@@bens3767 green lines and someof the apps not working like Plex and cutting in and out as if something was on its way out.
Thank you. We’re going to try and fix our first generation Samsung “Smart” tv.
I didn’t know anyone still fixed TVs ! Thank you !
The last television I repaired, I rinsed out with Dawn dishwashing liquid and a hot garden hose. I gave it a good wash out let it dry a week it's been running ever since about 8 years ago. The detergent did a better job than air blast on the affected high impedance circuits.
Great video, good job. I do have something to add that may be helpful. When sourcing new capacitors it is always a good idea to increase the voltage handling capacity but be sure the dimensions are the same or close enough. Even more important, especially if the faulty caps are swollen, is the temperature rating. It is likely the caps that failed are rated for 85C and for a little more money you can get 105C or above rated caps. These will last much longer and with the money you're saving why not make your repair last? Also, electrolytic caps dry out over time and are a big failure item. It's a good idea while you are in there to replace all the large caps if you can afford it. (the small caps are usually safe to leave in as they are mostly signal handling or dc blocking components and see much less stress)
Keep up the good work!
Bat
Good information. I had pulled the back on a donated 40" and had visually identified two swollen caps, but decided to replace them all...and it worked. I got lucky
I just gotter say........... there seems to be alot of people slagging this man off. My point is, , when you all quoting how long you been doing this and that and mocking this man................. i say "fcuk off" and do your own channel........ this man is trying to help people that maybe cant afford to run to people(maybe like you'all) to fix these kind of tv probs. for those guys i say ( as we do in England" JOG ON!!
Mich Callen why does it bother you?your life must seem pathetic for you to care about what others think.or do,for that matter.just chill

You just got a new subscriber I love fixing stuff like this.
Me too,im diving in! Nice TV i found it,so i like learning new stuff,
As an experience tv engineer i can say the presentation is very good
Exactly why the Right To Repair movement needs to progress. Save the planet and extend the life of equipment with minor issues.
I salute your unrelenting knowledge sharing technique. Keep it up.
But can you put me through on Laptop repair and sourcing for parts?
i go on ebay, usually its power port that needs to be soldered or replaced.
Mikail Okewole, if you're doing laptop component replacement? then due to their small size I've often used a 'Solder Paste' which is a fluid you simply squeeze through a syringe and it becomes conductive after drying - it beat getting a clumsy hot soldering iron into those tight spots.
Nice! And very smart to reuse equipment that’s not damaged! Thank you
Man you're good, something is telling me if I continue watching your videos I will learn a lot, thanks.
THIS is what I love about UA-cam! Thanks
Very informative, and makes me want to watch more videos! I have an old tv on hand with the same problem; I was about to give up and toss it, but now I think I'll open that puppy up and see what I can do. First though, I'm going to have a look at your other videos to see what else I can learn from you. I know it's not a new video, but you have a new subscriber. Good work.
I’d never be able to apply this to fix my tv, but loved watching.
Just found your site. Outstanding. Figured these days most old TVs were just tossed and a new one bought.
That's what they want you to think. That is also why they installed 25v capacitors in there, they will expire more quickly in my experience. I've done this repair on many monitors myself, and i always install a higher voltage, and i have yet to replace a capacitor ive installed.
thats how they make money...everything breaks down so quickly

Fantastic. I luv all your Tutorials. Crystal clear and vivid.
Began working on this and opened it all up. Unfortunately I have a fairly obscure Blaupuntk tv and the only matching Main Board is going for £45 on eBay :/ But the video was really neat and I'm glad it's helping other people
I like how it says easy fix when I’m completely lost
It is but I think you are a little too young for this tutorial
@@isaiahdrustani3568 LMAO I am 30 years old and even I am completely lost lol.
This is really good to watch. I believe I can learn by watching a professional doing things. Thanks.
That was really good, and taking time to pass on your knowledge is full credit. Really appreciated, big thumbs up, subscribed, and happy new year.
thanks, welcome to the 200k sub club that you help us reach, Happy New year!
As a fellow Tampa-area resident ... thank YOU for sharing & creating content that has grown my understanding!
I am currently working on a SHARP 70 (LC-70LE755U).
The screen works - - but - - has a "wavy" picture. I have individually replaced TCon + PowerSupply +IO board (testing image after each install).
Unfortunately, zero change from original screen fault. Those are the only boards ... minus some edge lighting + wifi card.
I presume the LCD screen is not damaged ... since the lines are not fixed.
At this point, I dont know what else I can do to repair ... besides maybe stripping down the chassis & replacing the LCD panel - - as a "long-shot"
Very good work. I have been repairing electronics since the 1960's with electron tubes and later transistors and later microprocessors and very often when troubleshooting begin with the power supply.
Man I've fixed so many TV's due to bad caps. Great video.
Don’t forget to remove that ring when you’re working with live circuits.
Yup
AS A 50 YR TV REPAIR VET I GIVE YOU A 10 OUT OF 10 RATING I THOUGHT REAL REPAIR WAS GONE
YOURE STILL ALIVE OMFG
@@dadushj4468🤣🤣🤣
I had this same issue a few years ago. I checked out a similar UA-cam repair video. I had one capacitor that had swollen and blown a hole thorough it. Cost 50p to replace. Soldered in. TV worked and is still working.
Watched you video for 1:35 minutes. TV fixed. Thank you!
At 2:30, the first thing I spotted was the bulging tops of the electrolytic capacitors. Capacitoris Bulgitis is a firm indicator for a transplant operation. :)
I had 2 x "Bauhn" brand (from Aldi) TVs which both failed in exactly the same way as the TV you're repairing (red LED and clicking when you try to turn it on) and when I opened up each, I immediately spotted the bulging caps so I replaced them and now I have 2 working TVs. :)
There's been a rash of electrolytic capacitor failures recently (over the past 10 years or so) and now they're always my first suspect.
Thanks bro. Super appreciate you laying down the knowledge like this!!!!!
If the caps are swollen it's likely that there's been an overvoltage so fixing them might be temporarily.
I've replaced the capacitors on a computer monitor and a 46" Samsung. The monitor I had owned and the 46" Samsung I found in the street. Another 46" Samsung I bought at a Garage Sale for $5.00 and all that was wrong was a loose ribbon cable. Then I was given a 52" Samsung with horizontal lines that come and go. Sometimes I would take an HDMI out and back in and other times there were no lines or the lines just went away after five minutes. The total cost for 3 remotes, 3 TVs, and capacitors is about $25.00.
Very helpful . Nice way of teaching. Thanks Tampatec. I always enjoy your teaching. Highly appreciate it. A Big Thgumb up.!

Sir very helpful nice way of sharing n teaching, thanks TampaTec good instructions, really enjoy ur teaching, Highly appreciate, A Big ThgumbUp
Yesterday I managed to fix an old LG tv the same way.The tv would power on but it wouldn't produce any sound.turns out the 6volt rail was showing only 3 volts,and the reason was four swollen capacitors!
"Thank You", thank you very much 😎
A myth about leaded solder - there are NO lead fumes coming off it. The fumes are the flux. These fumes aren't good for you either, but lead has a boiling point of 1749 °C - your soldering iron will probably be at less than 350°C so there will be no lead fumes. The lead WILL come off on your hands so hand washing IS important. To avoid the flux fumes, you can use a small fan (e.g. a spare 2 - 3" fan you recovered from something with a wall wart PSU). Don't use a large fan as that will cool your soldering iron tip off. In industry we commonly use vacuum fume extractors (expensive), but we are dealing with OSHA and people who may be doing hand soldering all day (e.g. rework operators).
I like how you get right into it instead of introducing us to your family, pets & extensive network of amazing friends & their hobbies..blah-blah. Info videos should inform & you get it.
@Tampa Tec Thanks very much for the help! I'll probably attempt this, now that I cannot find a new power supply replacement board anywhere, and even used boards are rare.
It did look like some of your capacitors had "non-flat" tops (the Xs are carved in the top in order to give way when the insides boil and give a visible sign of cap failure).
Reminder: Voltage is an "across" variable. Current is a "through" variable. Voltage appears "across" two points. Current "flows" from one point to another. Voltage can appear across a pair of points without any current flowing. Current can be flowing between a pair of points with no voltage across them.
You need a vacuum solder sucker tool. Cheap and makes removing parts easier.
Hes using one.
@David Hanson
Are they not the same thing?
My samsung stopped after 2 years and it was the capacitor! gave it to my dad to repair made it for like £1.
there is missing part checking voltage of power board after replacing the capacitors.
I just did a DVD with a bad filter cap, I was actually looking for it since the menu screen was showing a faint 60 cycle hum before it died. I did TV repair in the 80s when transistors were beginning to dominate, it was all component level test and repair, here I am 63 years old and still playing with this stuff, too much fun.
Thanks for the great information. You saved me a whole lot of money. Simply unplugged my tv, baddabing baddaboom. T.v. works fine
Thank you very informative
I've had to change the power board on an old Samsung LED 46" and the cooling fan on my new Samsung 65"UHD TV. It was very easy to do.
I repaired my tv with a hammer.
Lol.
Me too.
e.i mccool Lol that's hilarious made me literally laugh out loud 😜
Same here👋😂
.22cal. works well too!!
first time TV repair video .. And loved it learned a lot thank you for time and experience.
be watching lots more. cheers!!!!
Dude I have started studying electronics . I have a long ways to go that is very interesting thanks for posting
I was told by a Samsung Engineer after telling him that I trouble shoot byYou Tube videos and that you can fix a TV by looking at Tampatec on You TubeTV.
One video I watched said sometimes cheap knock offs are installed that aren't rated what the capacitor states. Therefore it pops. His video was exact same replacement. Fyi. Peace
you are very good at this, but if i tried to do this i would end up blowing the house up
Kevin Godding.
i need the capasitor kit
Nice work, did this with old plasma TV and it worked for about 3 months and then went out again. Went out and bought a Samsung smart TV after that. the Samsung went out about 8 years later. Sent the board to this repair shop in California and they repaired the board and sent in back in a few days. It is still going strong 2 years later. It cost me $75, so it was well worth it.
Great video, I love how you don't go on and on about unnecessary things! You get to the point, offer tips & tricks and get the job done!
Most people keep this knowledge to themselves; they hoard it, use it, over-price their labor cost to do the repair and try to do the get rich quick scheme. I love that you share your knowledge and seem to share the principle
“If you give a man a fish, you feed him for a day. If you teach a man to fish, you feed him for a lifetime.” Very impressive!
Great vid Tampatec, I'm very much like you, fix tv's when they can be fixed easily. Now, newer tv's all have cracked LCD/ LED problems (for the most part) which is a costly repair and not worth fixing anymore. I'm curious if there's a way to salvage the working half or portion of those screens and port a rasbery pi or arduino to throw something up to at least make some use of them..
I have a Vizio plasma no picture but audio work good do you have any ideas
most cases it's sustain boards and / or buffer boards, Plasma TVs break often, they get really hot so try USB fan
Ok thank you my friend
Tampatec I have had the same plazma tv for 5 years. I got a great deal on it because they were going led on all of them. I was told this one was the longest lasting best Plazma tv out there. I guess the guy was right. Its an LG. The salesman said it was a shame they were getting away from plazma because mine was the way they should have all been made.Once its done,its done. I will be hunting for an Led style that needs repair as a back up. I am really handy at electronics and testing so It would be fun fixing a dead one.
Could also be a dry joint caused by heat.
Definately sounds like its broken.

Brad K ok that was 😂
idiots
I have a sony bravia 32" lcd. It stopped responding. No buttons work, the remote doesn't work but when its plugged in it comes on. Its stuck on one channel. Any ideas?
a rough guess is that its the tuner control and software control pcb, the part can differ depending on what world region you are in, unless your a tech its not something you can fix (ive 30yrs experience and just swap them out because my labour would cost the customer far more,) but they arnt cheap so unless the tv is quite new (which at 32inch it prob isnt), id say its BER (beyond economic repair) sorry bud :(
Needed to understand how tor repair a tv i got from my brother as it randomly stopped working now i know what to look out for! Thank you, lets see if its an easy fix
Thanks for this. Recent winds of fortune require that I repair the things that oppose me. Your video is appreciated.
