This video popped up on my feed probably by the divine intervention 😂. I have a Tv that’s been sitting on my dresser for almost a year, from a power surge. I called for repair and was told $250.. I wasn’t sure I wanted to pay that much to repair my tv. Coming across this video, plus actually doing some searches on the topic, this video is by far the best video I’ve come across. I ordered the Multimeter, so we’ll see how it goes when it comes in. Thanks to your video, I believe I can fix the Tv myself! I’m definitely going to try.
You got this!
This allowed me to fix my tv for $20 rather than not be able to afford a new one right now. Thank you for posting this.
That is great to hear!
I'm about to attempt this project myself but furthermore I ponder as I have a 36' model of same brand and model and am wondering if I could rob the 36' to Frankenstein its board into the 70' fyi the power board is not the issue it would be the hdmi board.....
Could you just replace the HDMI chip instead of the whole board?
@@mrswiss Potentially, if you're equipped to do surface mount soldering. That's beyond the skill level of myself and most people though, not to mention needing a nice enough soldering iron and de-soldering iron to pull it off cleanly. Cheaper to pay the money for a whole new board, especially considering the time spent in labor.
The way you talk, explain and do it is amazing 👌🏻
I've been watching youtube a long time, and have never seen a more informative discussion with comments and replies by the originator of the video! Well done FregalRepair! You are at the top of the list for helping others! You give me courage to tackle our Visio that is dead from a lightening strike. I bought one of the multimeters linked above, I hope you get credit for that. :-)
Thank you for your kind words! I’m glad to hear you have courage to fix it.
brilliantly explained, you've turned quite a daunting task into a simple step by step and now im about to pull my TV apart! thanks for the great video :))
Thanks! I hope you can get it repaired.
Never thought about the surge coming thru the hdmi ports!
Thanks good to know
Well done. Not more information than needed but enough to do the job.
anyone here watch this video because ur tv got hit by lightning?
Genius .....
How did you arrive at that assumption...
@@tvuser1 basically at my home we use attenna signal while i was watching a tv show (i was watching a tv during a thunder storm btw) about maybe 2 hours after watching a tv show then boy we heard a really loud bang sound in our backyard(we installed the attenna at our backyard btw.
@@chopstickftw0121 jus trollin.. dont mind me :-) hope you were able to fix it though
ChopStickGaming ....nope......I just ordered a 65 inch Samsung and I just like staying ahead of the game. In case it ever gets hit by lightning since I live in Florida
@@willie3528 hehe ur local florida man
Thank You! Thank You! Thank You for this video and for helping me to find the part I needed to do the master board replacement. A lightning strike fried all my HDMI inputs. I had never dreamed of being able to do the replacement myself but with this video I was able to do it, and the new master board for my 86" TV was only $29.99 plus tax, including shipping. Doing the job was a bit nerve wracking, but I did it and it worked perfectly when I turned it back on. Very kind of you to help others with videos like this!
Thanks for watching! I usually buy my boards on eBay. You can use a website like shopjimmy.com to find out the model number of the board you need or you can buy directly from shopjimmy
@@FrugalRepair I got it for much less on Ebay. Thank you!
Very good video. I will have no trouble isolating what to fix with your tutorial 👀... THANKS
Superb. Saved hundreds in a new TV!!!
That was very helpful Thank You. I will definitely try to fix my TV with your instructions. 👍👍
Thank you, sir!! And my Bravia has new life!!!
That is great to hear!
Great and informative video, just got a TV that was struck by lightning from my girlfriend’s family. Gonna give fixing it a shot and see what I can do.
Thanks! Great to hear you are planning to fix it. Post any questions here if you get stuck.
Excellent video thank you. I have a sony xbr_65a9g oled. Lightning strike also. After reading through all the comments i didnt find one talking about replacing power supply and control board. Then after only having sound on the tv which im happy to hear. But the display is still black. What would u look at next to get the display back?
Awesome video! Thank you.
Thanks!
Fantastic video, pretty much to the point! would you please advise where is the best place to order parts for the TV?
Thanks! I usually use eBay.
5:55 thank you!! Can’t wait to go home and try this. My TV was plugged into a surge protector along with several other items including my cable box. My cable box was connected to the TV via HDMI and it’s only my TV and cable box that got damaged. All other items on the surge protector are okay. When I called the cable company to replace the cable box, they cam and simply bypass the HDMI out port on the cable box and used a port (don’t know the name) but the wire that was use to connect to my next tv had a 3.5mm jack end into the cable box and some red and white and yellow ends that went into the TV, RCA I believe…
So the cable box power source seemed to not have been hit only the HDMI cause light was coming from the cable box just no display. The light that normally come on my TV when plugged in doesn’t so maybe it’s my power board and also the main board.. either way I’m excited to go home and try this myself! :) thank you for this wonderful video!!
Well done! Ordering my main board and we'll see how it goes.
Thanks! I hope it fixes your tv.
Where can i get the board to buy
@@sunilbaboolal6209 ebay
You deserve a like my friend
Thanks!
Awesome video and very informative.
Thanks for watching!
I didn't hear back from you, but thanks for the video. I got someone else to look at the power board. It looked like the PWM controller melted and I didn't know what else went on so I replaced the power board and presto, it works! Thanks for the video.
I'm sorry, I get more messages than I can respond to. Glad to hear you got it repaired!
well made. thanks
Best video thanks!
really good video and clear explanation. thank you 👍👍
Thanks!
Great video! Thanks
Thanks for watching!
Very nice informative video, my tv VDIGI MODEL NO 39E100CT shot down after thunderstorm and lightening
Great video, thank you . Do you have a site you can recommend to get the main control boards?
Thanks! I usually buy at ebay
Great video thank you, but 1 question, I have multiple standby 5 volt pins and they all show 10 volts when tv plugged in so power supply bad? vizio lcd
Thanks! That doesn't sound like a voltage you would see on that power board so that is a good guess that it is bad. Are you sure you have your black probe on the metal chassis and red on the 5v pin when you are taking the DC voltage reading? Just checking that you are measuring the correct electrical potential.
Very smart,, I have a lot of boards out of these tv's if you ever need any let me know, liked vid
Ok, will do
Thanks for the video... I just found out my main board was affected buy the lightning... but can't find where to buy LG 32lb552u-tb main board. kindly assist
Great job diagnosing it yourself! I looked (like you did) and couldn't find one. I would suggest that you see if you can find out if a different model of tv uses the same board. Sometimes that is a way to find boards you can find by a direct search.
very good description, thx a lot.I tested my vizio power supply board ceramic fuse, and it looks like it is opens I will try it now and if works, all the credit is for you.This happened after lightning strike, no power.
Hopefully you can get it repaired! Let me know if you have any other questions.
I had two tv's hit (along with two DirectTV boxes). On the first tv I checked the fuse, howevere I don't have the same type of multimeter you have. I went to ohms and checked, without power, it showed no resistance. I then connected the power cord and checked the standby voltage. The board indicated 5v on standby but I registered 3 and then 4 volts. I assume this means the power board in working. What are your thoughts? I don't want to buy a new main board until I get some more information. Also, there was no obvious burning or scorching on the main board.
How to replace backlit strips on the smarttv......Thanks by the way for been of great help...
Thanks. Working on a backlight is one my next videos I’m planning to get out. They are shorting out on a lot of TVs.
Thank you so much Sir, it was super informative. My Sony Bravia android tv KDL-43W800C. Just got short by lightning 2 days ago... Do you any idea how i can get the new mother board?? I would be very greatfull.
Thanks! I usually would buy one from eBay. Make sure to search based on the printed board number on main board.
Yeah was really a good video buddy.i Appreciate it
Thanks!
Good afternoon. My sharp LC-60E69U does not power up. But I do have the 5VDC standby voltage present (but no other power supply output voltages). The standby Red LED is on too. The TV does not power up. Do u think it's the main board not giving a signal to the power supply to turn on the 12VDC, 24VDC, and other outputs? Of course the power supply fuse is good too. I have both replacement boards. Should I replace both first or just the main board first? I don't want an old board to damage a new board. Thnx
where do you buy the boards? great video
Thank you! Much appreciated. I buy from anywhere online. Most of the time the best place is ebay.
Great video! Where did you purchase the main board? Thanks!
Thank you! I bought it on ebay.
Your video was awesome. Where can I get those parts?
Thanks! What part do you need? A new main board? I’d buy from a reputable seller that has a good price. Most of the time eBay is my go to source.
Thanks good video. How much was the main board ?
Gaby Tjintjelaar It was about $60-70.
@@FrugalRepair where can I find them?
Great video, and thank you! I have an issue with my 70” JVC LCD 4K TV, and would like your (and anyone else’s) opinion.
The TV has been rock solid since it was delivered in 2019, up to now. It’s been used an average of a couple hours a day since. I was watching a movie a couple weeks ago, and the screen dimmed, then went black, with the movie and it’s audio still kicking along fine. I turned it off, unplugged it for a few mins, then plugged it back in. The red IR remote receiver light came normally, and I hit the “power” button on the remote. And yes, I am aware this is only a “stand by/sleep” button, and doesn’t fully power the unit down while plugged in.
TV turns on, screen illuminates, and it seems to be working fine again. I walk over (it’s wall mounted), and place my ear as close to the bottom of the TV as possible. Now I can barely discern a faint, slight buzzing emanating from inside the TV. No burning smell, though. I sit down, go back to my movie, and 10 mins later, same failure, screen goes black, with audio continuing.
So I repeat the unplugging, holding the power button down, doing the remote code thing, etc., from all the FIX YOUR JVC TV videos on UA-cam. No luck. I wasn’t really surprised. Now this TV’s AC power has not been run through a true anti-spike strip (just a regular power strip), or any other power conditioner type device. So I’m suspecting the power board. I grab my Kill-A-Watt meter, and plug it in to the receptacle the TV was plugged into. Both outlets on that receptacle are showing 121V @ 60Hz. Normal. So I then plug the TVs cord into the Kill-A-Watt, and the voltage reading drops to 89V, then 112, then 119, back to down to 110, and so on. It’s basically all over the road. Same thing happens on the lower outlet. I unplug the TV.
I pull off the back panel, and there up on the top right side of the board (cold side), a single capacitor next to the dual LED wiring connectors is “domed” on it’s top, with obvious signs it’s spewed out a bit of some black dusty by product of whatever over heated goo is inside of it. Not good at all...
So in your experience, have you ever seen a TV with a failure on the power board like this continue to work for a few minutes at a time, before failure?
And if so, what do you think the likelihood of this failure type damaging the main board is? Or any other component? Specifically the power button module, and/or T-Con board. And any idea what is happening with the voltage reading at the power receptacle? It seems like the board is “back feeding” shorted power out of the board directly into the cord.
Anyway, thanks very much for your time, and attention to this novel of a post, and for any reply! PS I have the board out on my bench, and arrived here in search of videos on how to bench test a live (powered) board out of a TV.

Thank you so much...
You're welcome!
Great video! This is the first time I heard the explanation about the surge coming through the HDMI. I pretty sure that happened to me as our 60in Samsung was in a surge protector, but one connected device was not. I get no standby light at all and ran through your troubleshooting. Fuse is good. Finding that if I disconnect the power and main board connection and then connect power, I get backlights. But once I reconnect the two together, nothing. So this tells me it must be the main board? Though I can find not burn marks or puffy caps or anything that looks bad. Should I just replace the main board since power is getting to the power board?
Thanks! Usually, you need the main board to tell the power supply to turn on the backlights. That is curious that they are coming on without the main board attached. You may need to take measurements with your multimeter to see if the standard voltages are there. Or if they fluctuate.
@@FrugalRepair Thanks for the reply. The pinout on the power supply has 13V for 4 pins. If I keep everything connected (main to power supply) and plug in the TV, I only get ~10V (just under) on each pin and no backlights. If I disconnect the main board from the power supply board and retest I get the full ~13V on each pin. What do you think of that? Also standby light never comes on and remote or manual power does nothing.
I’d make sure to check what is printed on the circuit board. It usually tells you what each pin’s voltage should be. As for what you mentioned, I’m not sure. You can test to see if there is voltage going to your input bar (where the on/off button is), this will give you more clues. That is a standby voltage going there.
@@FrugalRepair Hey man, appreciate you getting back to me. I know it was a loaded question and super hard to answer without seeing it. I'll test a few more things. Thanks!
@@FrugalRepair All Voltages checked out so ordered a main board and installed it last night. TV picture is back!! Fixed!! Pretty sure it was the HDMI connection that fried things, just like you said in the video. Great video. Thanks for all the responses!!
Great teachings there. So what shop did you buy the board? Is it a original or a duplicate?
ebay
My aunt has a sceptre tv got struck by lighting everything works but the speakers it just popping sounds as they talk are music plays is the speakers blown are what do you think could be wrong
I have a jvc 47" Model # JLE47BC3001 I have replaced the Main & power boards and the tv still turns off after a very few minutes & sometimes seconds after turning on so obviously those we not the issue! Do you have any ideas what it could be!!!
Good stuff! Where did you just order the new board from ?
Thanks! I usually buy from eBay.
Hello, If my standby light is on, what is the name of the board I should purchase?
What's the best way to find replacement parts for TVs? I know it's my main board that's the problem, but I've yet to find a place that sells it. (lighting damaged the cable box and that damaged the main board)
eBay is the first place I usually check.
Where did you order the resistor and diode?
I have replace the power supply board, main board, motherboard and the small board theta has the power and channel change buttons.
My RV was hit by lightning, it came on a couple times after the lightning strike but then stopped powering on completly.
Once the four boards were replace it powers on, but the Visio logo screen never comes on. It’s clear that lights are on and the standby light comes on but then cycles off then back slowly taking the front screen slightly on and then black again.
We tried turning the TV off unplugging it and holding down power button for ten seconds to power cycle it but still doing the same thing.
What should I do at this point?
just had a major lightning strike this evening...no thunderstorm, just a loud crackling of lightning one time. Iwas watching TV at the time and when it happened i could hear a clicking noise coming from behind the tv...I have 3 surge protectors...tv was plugged into a really good power surge protector..now i have no power light no pre amp light nothing...everything else is ok, computer, receiver, modem all are plugged into same surge protector and they survived....is there an internal reset button on my tv perhaps? it is a Sharp LCD tv model # LC-50LE442U it's about 4 years old...costs about 600.00 to replace it. what should I do? thanks for reading this....
Sorry to hear! The light in the front of the TV is called the standby light. Check the fuse on the main power supply (unplug the tv and take the rear plastic back off ) as a first step. Watch the video and let me know if you have more questions. There isn't a reset button, unfortunately. But if you have a multimeter and a screwdriver you can fix the tv yourself. The problem is either on the power supply board or there is a short circuit on the main board (which was the issue on the tv in this video).
@@FrugalRepair I have a Sony XBR-65X900B I also was hit by lightning through cable and replaced both the power supply and main board and still TV will no power up. When I plug power in outlet i hear something engage on power supply, I then push the power button on tv. I hear a click but still no red light on front of tv or does it power up. When I pull plug from tv I hear the power supply make a noise almost like a contact sound. Any ideas ?
I have a MSI mother board that went inn the blink after trying to fit a pci card...Could no send it to you to see if you can fix it for me?
Thank you for putting out a great Video!! Recently a lightning strike fried my router, modem, Roku and firestick. My TV powers up, and stays on Standby. (OPC is on) and I am able to see menu options. But Roku, Firestick and other HDMI video players do not display any pictures. I tested all HDMI ports. Confirmed that the HDMI cable and the new streaming players are working fine by testing them on my computer monitor. What board should I check/change ( and a good place to buy it).? TV is a Sharp Aquos LC -C4067UN.
Sounds like what happened to the main board in this video. Your current main board has a board number on it, you can search ebay on that number or the model number. I usually use both to find the best one.
@@FrugalRepair I ordered a part online and was able to repair it on my own. TV works now! Thanks to you, I did not have to buy a new TV!!!
Wow nice video some one gave me 2 4k tvs that got hit by lightning said cable box was hook up fried the boxs and 2 tvs no stand by lights fuse good power. supply main baord looks ok no burt chips but guess i go from main board first go from there lucky seen your video would bought a power supply first
Well, this tv I recovered from someone who isn't as inclined as I am and they set it out on the curb. It's a beautiful Samsung 55", that was well cared for, and looks less than 2-3 years old. I noticed a 2 pole plug, not like my Sharp's polarized plug. But, I remember that our Utility Provider had shut down for "Scheduled Maintenance" a few weeks back. I'm assuming it wasn't plugged into a surge protected power strip (all of my electronics use them), and when their power was restored their TV was not turning on. I am a Journeyman Industrial Master Mechanic, and if needed, I know I can fix a Military Tank 😊😁😎
This will become a monitor for a Dell Inspiron sff tower that I also recovered that someone discarded... I cleaned out the Roaches, and a minor spill, and am upgrading it for my purposes 😊😉😁😎
How is this different from fixing the same issue with an LED TV (Sony XBR 65X850B)?
Great video man. I have a Hisense LTDN40D50TS TV that died following a lightning strike on the satellite dish it was attached to. The red/blue LED on the TV comes on and stays on but there's no picture on the screen. I have found that the TV uses a TP.S512.PB83 board that is found on dozens of other TVs, such as Supra, Haier, and Baird. Question is, would a mainboard from any of these TVs work? Cheers.
Thanks for your comment! You are correct that some main boards are identical to ones used on different models. If you make sure the board numbers are the same and you visually inspect it (to make sure the connections are the same, etc) then I think you should be fine. At least, that is what I do. When searching for a replacement board on ebay, I'll do at least two searches, one for the model number and one with the board number.
@@FrugalRepair The board number in my case is TP.S512.PB83, the same board that is in many other TVs. I have carried out the two searches as you suggested. The search for my particular TV model number yielded nothing. However, the board number search yielded several options. Quick question, can an identical and matching board refuse to work with a particular panel?
@@denniskiplangat5029 I would think it is fine. If you have made sure the board numbers match and the components and connectors are exactly the same. It is possible that the connector style might be different (so you'd want to look at the photos too). You can always buy from a seller that accepts returns too to add another level of safety, if you want.
I changed all the components now the TV backlight turns on but the LCD is lit but not showing anything. before the TV wasn't even turning on but after buying the power supply and new motherboard the LCD backlight turns on but did not show anything, speakers work too but no image. what do you think I am missing here? maybe the entire LCD is burned?
What sort of website do you order the main (or any other) board from? Are you dependent on what is available on eBay, or do you have a trusted source that you like to use?
Ah reading through the comments and see that eBay is your go-to. Welp, not my favorite answer, but it'll do. Thanks for the step by step!
great video!!!!! what about a 4k tv?
Thanks! Yes, a 4k TV would be similar. The main difference between a 1080 and a 4k is the lcd panel itself. There would still be a main, power, and sometimes an led driver board.
I'm reading that quite a few people had their TV's plugged into a surge protector and that the power surge still caused damage. I live in Mexico where power comes on and off frequently. Had thought about getting a power surge protector but didn't get around to it and about a half hour ago my TV just zapped out, followed by a strong smell of electricity burning in the air and no standby light...I'm assuming from a power surge. Do you think power surge protectors work, and if so, do you have any recommendations on a good brand?
I don't have any recommendations but it sounds like having a good one would be a wise decision. Beside the main power cord, the power surge can come through another device connected to the tv (ex; hdmi), like it did in the tv in the video. I'm sorry to hear your tv broke. Hopefully the diagnosis will be fairly easy if there was a strong smell it may mean you can visually see which board got damaged.
Hi sir! I have an LG LW4500 tv. Its an old tv but i want to revive it. As far as i can remember, i think it got broked by VGA (or maybe HDMI i forget). When i plug in to the wall outlet, the tv has a stanby light. When i power on, its like normal. The LED light turns from red to white, but theres no display on the TV. So its definitely the main board right? Could it be the Tcon too? Also i havent taking apart the tv yet, maybe if i got time. I hope you answer my question :D thank you sir. (Sorry for bad english)
It could be any of the parts inside. It could be bad capacitors on the power board. It could be messed up firmware chip on the main board. It could also be a bad backlight. For a bad backlight diagnosis, turn the tv on and shine a flashlight on the screen. If you see anything then its a bad backlight. You would need to get more information to diagnose it further. Also, physically look at the boards for any burn damage.
I have the same TV. The power light comes on, but no screen picture. I know it is getting power, because the optical audio on the back, is lit up. Blank screen though. Does that sound like I need to replace the main board like you did, or could that just be the fuse you were talking about?
Did you go through the guide I have? There should be a link in the description. You want to rule out if the backlight is bad.
My Sony Bravia standby light works but it only stays on for a few minutes.
The longer I leave it unplugged, the longer it stays on. But it eventually turns off in a few minutes. And I did check to make sure the timer was off that turns it off after a certain period of time.
My guess is that something is okay while cool, when it gets heated up, it turns off. Just what would that be then, a fuse? And in which part the Power or the Main board?
Hi I have a question....
I Have a Vizio e500ar. We had a lightning storm and a big strike happened near our house. After that the the tv stopped working. It won’t cut on and doesn’t have any lights. It was plugged in the power strip, but the other things on the power strip were still working and so is the power strip itself. The tv was connected to both the antenna and satellite dish. We have another tv connected to the antenna and it is working fine and we have another connected to the dish and it’s fine. We were even able to connect the dish Box to a new tv we had in the shed. It at first didn’t work, but we then realized that the hdmi cord from the dish box to the tv was no longer working. We got the av cords from the Joey in the other room and connected it to the tv since we didn’t have another hdmi cord. It’s now working with the new tv but the old tv still won’t cut on. Any tips?
Did you test the voltages on the power supply?
Thanks for the interesting post. I have a Samsung Tv which was hit by lighting too however the standby light does come on once the power cord is plugged in, no visual all I get is buzzing sound from the Tv. What could possibly be wrong with the Tv?
Thanks in advance👌
Thanks! Did you check the voltages or try to isolate the problem to the power board or the main board? Can you hear which board the buzzing is coming from? (that would be a clue if it were me).
Thanks @@FrugalRepair I have not opened the Tv as yet. But will certainly do so soon.
Awesome!
Thanks for watching!
Lightening attacked mine tonight, Samsung UE48H6400AK, works still but it's like the volume stuck down and on off button on the remote, even when i remove batteries.... Standby flickering aswell
So I'm dealing with this issue but tv does turn on still board looks OK but screen shows no picture just vertical lines that shift color any suggestions?
Hi
Where do you get the schematics from?
Soooo, if the fuse is blown, should I just change the fuse or change the whole power board ? And if I just change the fuse are they a pull our or a solder hook up ? This is a great video got hit by lightning 2 days ago, no power, no standby light. Haven’t pulled it off the wall to look yet, it’s 75 ‘’ RCA and is 130 pounds and I’m 80 years old so I don’t want to take it to a shop, that’s a major job. Thanks again for your video . EJ
It may be that you only need a fuse. Sometimes the fuses are soldered to the board and sometimes they are not.
Did you ever use a headlight that fits on your forehead with a headband? I use them & they work great.
Yes, I have a few of them!
I have a Vizio LED tv that I came home to and it just keeps powering on and off. Can’t use any function. There was a storm recently however I wasn’t home. Any help appreciated .
Is it powering off at the same point? Or does it shut off at random times? Does the tv stay on long enough to get past the Vizio logo when it boots up?
No. It boots up to the logo. Then shuts off. That’s as far as it goes.
@@edwardfessenden589 Hmm, I'm not sure. I'd try disconnecting everything and then testing boards/peripherals and adding them in one at a time. You might have a shorted component that when the tv gets to a certain point in the boot process that it shorts out and takes the tv down. For example, the hdmi mux chip (like in this video) could be damaged.
FrugalRepair tested power supply board stand by voltage and it is ok. Would T-con board cause tv to turn on and off by itself? I’m thinking main board needs to be replaced. Don’t know how to test main board
The correct tools help significantly. Splitting the cases on plastic cased electronics should have a tool that is a plastic pry tool, that kinda looks like a Screw Driver‼️‼️‼️
My neighbor and my TVs both went out at the same time. We think we got his problem worked out, but I haven't been able to figure mine out yet. My TV (Samsung UN40FH6030) is turning on, however the screen is VERY VERY dim. The controls seem to work as well. I checked everything in this video but none of it seems to be the issue. The main board looks clean and none of the chips ~look~ damaged, though I DO think it died through the HDMI (my PS4 completely died in the surge). Any ideas other than dropping $60 on a new board?
The dim screen is the backlight. did you try going into the settings and increasing the backlight (ie screen brightness) on the tv? let me know. if all of the functions of the tv are there (except for the dim screen) then your problem is probably not the main board. It could be the led's (backlight) themselves, the power board (which supplies the power to the led strip), or some TV"s have a separate led driver board.
Hi mate just wondering that my tv was blown by lightning and it was through the lan wire for internet to the smart tv and it wont turn on ,so is it main board gone or powerline gone do you have any idea ? thanks
Sorry to hear! If you are certain that the power surge came through the lan cable then most likely you probably have a component(s) damaged on the main board. Before buying a new main board I would recommend that you test the power supply (like in the video) to make sure it has no problems. You can also search the main board for any visible burn marks for clues to where the problem lies.
I can't see any damage on the main board and the power board passed the fuse check and standby voltage check. Should I just replace the main board even though I can't see any damage? The TV shows no signs of power or sound when it powers on.
Thanks for this, my tv was damaged yesterday by lightning, before I buy one, I will try this..I don’t believe in taking it to anyone fro repair, is either I do it myself or buy one, period. Thanks for this video
I bet u south African....🤣🤣🤣🤣🤣
U scared u tv might become a doner.
Where did the new board get purchased from ? Thanks in advance.
Ebay
@@FrugalRepair Thanks much. Excellent video btw. Her refrigerator is one of those big expensive side by side with the big chest drawer freezer below. The digital board where you adjust everything is lit up but like when a digital clock goes bad, whole numbers don't read, parts of what you see are missing AND when you try to change anything, you can bump it up or down but it doesn't respond to the command. The 'enter' command doesn't work. A friend is in a gospel quartet and one of his members does appliances and says it has two boards and the one showing , if it looks funky , could be the culprit OR both could. He'll check it for nothing but it's WAY out on the mtn and takes an hour and a half trip to get there. In a situation like this, even costing me $150 + to get it to him and back, would throwing a board in it be advised, especially when you see it reading funky or should I bite the bullet and take it to him? I appreciate your time. It's expensive as hell and a only couple of years old, maybe ...3? I picked up a cherry black mid 90s side by side at an estate sale for $75 cash to get her by. She has lupus and didn't even know it got hit until she recovered from an attack and opened it up 3 days later. Woe! It'd knock ya down. I had more in getting it out there than I gave for it. Lol. I pay a friend to do it btw. Truck poor right now.
Nice bike in the background. What is it?
1985 Honda Shadow VT500. You’re the first to comment on it.
How do i know what board i should buy?
Ok I've figured out that my fuse is blown. How do I remove it and where can I get another fuse? Thanks great video..
You may need to solder it out. Some of them are only held in by clips so you can pop it out. You want to match the specs on the current fuse. So it’s usually printed on the fuse or on the board
@@FrugalRepair thanks for the help . this is the most informative how to video I've seen.
Hi great video. I commented a few days ago about it and wondered if you'd take a look at a suspicious (melted?) component on our power board (fuse was OK). I asked if you might take a look at it and you suggested I post a video. I posted a 10-second clip (twice) and it looks like its gone. Perhaps it violates a YT rule? Anyway, if I can still persude you, could I back channel it to you somewhere? Thanks, Steve
Hey , could I take a main board from a another tv instead of buying one and replace it?
That usually will not work because the connectors don’t match. Even when they do match, you have to ensure that the outputs to the LCD panel are the exact same as the original. Usually you’re safe if the board number printed on the PCB is the exact same. But that’s a generality, there may be other issues like firmware differences, etc.
I have three old TVs. They're from the late 80's to early 90's. One has a bad picture as far as color. Another shows a flat,squeezed looking picture. The third TV's power doesn't work. It may need a fuse. Anyway, I'm considering throwing them away instead of getting them fixed. My question is do any of these old TVs have any valuable replacement parts inside them that would sell on ebay?
I doubt they have any value. I don't think there are people still fixing CRT's. But who knows, maybe there are?
Thank you so much. My sister has a Emerson tv and hers got hit by lightning recently during a severe thunderstorm. Now the tv changes channels by itself and the buttons do not respond correctly.
Sounds like either the main board got fried, the button bar (input bar - the part with the actual buttons), or both got fried. If you have a separate input bar, try disconnecting that from the main board and use the remote control to operate the tv and isolate the issue.
Thank you so much.
My tv turns on and I can watch with antenna but my Roku HDMI does not work. Was Struck by lightning yesterday fried the modem when I try to put in another Roku device in it with a different HDMI it does not connect so I’m going to assume is exactly what you’re showing us but I don’t know how much a board would cost do you know roughly the cost of a board and where I would get it for a sharp tv?
Find the model number on the back of the TV, then look on eBay for a main board.
Where do you buy replacement boards from?
Usually eBay
Hello, I'm having trouble. My TV has the standby light on but no power up on no screen lighting. I checked the board for any burns, loose wires or detachments. And everything seems okay. But I ordered a power board anyway and got that put in. And nothing is happening. Standby light still comes on. Help, please. Idk what it could be.
Yes. I got 4 power sources and 2 tvs mesed up bu lighting. My sony android had external power supply so i just bought a amazon replacement. But my 55 LG tv have the power source inside . So i have to troubleshoot.😢😢😢
Where do you go to purchase new boards? Ebay, Amazon, etc.
I usually use ebay.
TVPartstoday.com Great prices (although shipping is a bit high) but received within 3 or 4 days.
Just wondering if not standby voltage process just replace power board?
You could do that. But I’d try to figure out what the component is bad first.
Hi, great video but i am struggling to find the compatible mainboard for my tv. Its not on amazon or ebay. Does anyone know which i could find it?
Did you also search based on the board number? Sometimes the same main board (or compatible one) is used on different tv models.
Yes i did, unfortunately result was zero.. do you have any other website suggestions?
I usually buy on eBay. Shopjimmy.com is another place you can try.
So my Sony 40in NSX-40gt1 was hit by a power surge/lightning. There was no light on the front of the TV. When I touch the 2 ends of the fuse with the volt meter- it beeps. So the fuse is good. Where the wires connect the main board to the power board is where my problem lies, I think. When I touch my voltage meter to the standby pin, it should read 3.3v but instead I get OL which my voltage meter says stands for Open Loop. Others have suggested getting a new power supply board as the easiest option, but i have tried finding one for my model and cannot. Is there a way I can fix this problem without replacing the whole power supply board?
Also i have checked for damage on the main board and i couldnt find anything that looked out of the ordinary so I think its just the power supply board that is having issues
If nothing is connected to the power supply and you plug it in and you’re not getting the standby voltage, Then you know the problem is on the power supply. I’m sure It can be fixed, but you would need to track down the bad components and replace them.
Good video, but my TV turns on okay, then I just get a No Signal message. The remote connects to change input, etc, but nothing there from cable TV in one HDMI port and no response from the fire stick in the other HDMI port either. I don't know what's up or what to do first. What do you suggest?
Is this after a power surge that the hdmi stopped working? Can you verify that the other inputs work (RCA? or coax?, etc) so you can isolate that the hdmi ports are no longer working. It is possible your hdmi chip died.
HI FROM GREECE TEAM.I HAVE ONE SONY SMART TV 55 2018 MODEL.AFTER LIGHTING STRIKE TV IS NOT WORK.I BUY NEW POWER SYPPLY BOARD AND TV NOT OPEN.STAND BUY LED LIGHT NOT WORK,MAYBE IS MAIN BOARD TO CHECK TO BUY?THANK YOU VERY MUCH :)
