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.

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!!

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?

@FrugalRepair

4 жыл бұрын

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.

Where did you order the resistor and diode?

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 is this different from fixing the same issue with an LED TV (Sony XBR 65X850B)?

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.

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.

If you are sure it is the main board that needs to be repaired then look at the printed numbers on the board. Vizio numbers tend to to be about 16 digits long with dashes every 4 digits. You can also verify the board number (part number) by going to shopjimmy.com and looking up your tv's model number. They usually supply you with the part number for the boards in the tv. Once you have the part number you can buy from a number of places online. I'd just make sure whoever you buy from has a return policy (to ensure they don't send you a dead board).

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).

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.

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 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.

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 KZread. 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. ~ Multimeter Rookie with a fire extinguisher handy 😜

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?

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👌

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

When you checked the volt on the 2nd chip you said put the needle on the bottom. Then on the chip. Where exactly on the bottom please?

MegaVicki1983 Do you mean when checking for the standby voltage? The other pin needs to be connected to a ground point. Any part to the main metal frame of the TV is considered ground.

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?

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?

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.

I lost one tv and the attached satellite TV receiver two months back and now another Tv (both old tube type) along with their separate satellite TV receiver. Both connected to the same dish having a dual output C-Band LNB (so actually two separate LNBs inside as both have separate polarity adjustments). Both TVs were also connected to the same Cable Tv system using a splitter. The technician said both TVs had the Audio/Video in/out sections burnt. One of the Sattelite Receivers also had audio/video "Out" sections burnt, the other receiver powers on (Displays ON) but does not boot ( this receiver has no burn signs and perhaps the software got corrupted).The technician suspected surge from Dish but the RF tuner sections of both receivers are not burnt. Both TVs sparked at the power plug in the wall socket when switched ON and died.No power up light whatsoever. The first TV showed full continuity at the power plug but the second TV showed an open circuit at the power plug. I checked the voltage on the Coaxial Cable (RF cableTV) and on setting my meter to DC it gave 0.7 to 1.6 volts (shows -ve when I switch cables so its perhaps a DC voltage) and when I set the voltmeter to AC it read 11.4 volts. Now I have a new LED TV and dread the cable could do harm. The technician says 1.6 volts DCis OK as the cable booster can add that (I doubt). Please help me diagnose the cause as I don't want to lose my new TV. I have pics of the burnt receiver board if someone wants to see.

@@Examoon The technician opened it.25k volts you are right.Actually I wanted to be sure whether its was the cable TV RF or the Dish RF that caused the trouble. Later I checked the Cable TV was passing 13v AC.I wonder if that was the culprit. I need to be careful with the new TV so research required. The surge protector is for the mains I believe .

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.

Looks like my 5 amp fuse is blown - good news! How the heck do I replace it? Does the old one snap out or to you solder a new one in parallel with the old one, or ?????

@FrugalRepair

Great job tracking down the blown fuse. Hopefully that is the only issue. Some power supplies have a pressure fitting to easily remove and replace the fuse. If you can't pop yours out then it is probably soldered to the board. You'll have to desolder/remove that one and solder in a new fuse.

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.

When I was watching a movie in my TCL TV suddenly I heard a pop sound and my tv is not working. I tried to connect my tv in another plug but my tv does not worked. There is no sound and no display. When I turn on my TV no white light is turning on. Please give a solution for this problem.

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 a 60 inch Samsung smart tv that was hit by lightning. It would not power on or respond to any button pushes or anything like that. The standby light was still on so I assumed the power supply was working fine, so using your advice I changed the main board. Now the TV will power on and flash the "smart tv" logo, but then it goes blank and nothing happens. I can't turn it on or off after that, I have to unplug it. Any advice?
