The TV shuts off by itself, many times a day, sometimes every couple of minutes. It always comes back on but a lot slower than the first time you turn it on. The mother board has been replaced twice for the same problem, but appears not to be the solution. Any other suggestions?

After reading several forums when my LG 42PC3D died, I went in thinking I had the answer. It would turn on, but then off immediately. The Y-sus board had a blown fuse. I didn't want to risk frying anything else, so I replaced the board rather than just replacing the fuse. When I disconnected the board, it would turn on and stay on. Now, with the new board, it powers up as soon as I plug it in (doesn't actually turn on, just powers up) but won't do anything. The screen is backlit with just

I have a samsung ln-t4053h that had a bad caps. I replaced the caps and the tv turned on fine and i put a flashlight to the screen and the screen turns on but the backlight is on 10 and it looks like its not on at all so that leads me to believe the backlight inverter. As I was testing this the power board slipped and touched a metal part in the back of the tv, sparked, and now the tv wont turn on at all. I figure that i shorted out the power board. If I replace the power board will me tv turn o

How do I find the power board in a 1997 big screen Sony TV to check the fuse? How do I check the fuse? I live in a house built in the 1890's, and last year there were 2 different tornados ,within 2 weeks of each other, that blew over trees on top of my power line twice in 1 month. My TV hasn't turned on since then. Is it the fuse I need to be checking? Should I replace the power cord, maybe just the cord is fried? It

I think I shorted out the power supply board on my Onkyo HT-R667. I was replacing some the capacitors to repair a hdmi switching issue. I was testing the repair with the top cover off. While it was powered on I accidentally touched the metal top to the top of the power supply board CMKM-P3X. There was a spark and the unit turned off. It won't turn back on. No lights. Can it be fixed or can I purchase a replacement board if this is even the issue. Thanks

Hi, I bought a Vizio L32 HDTV10A that didn't power-up. There were charred components on the power board (an 8-pin IC with heatsink and 2 resistors). I replaced the power board, and the power LED then turned on (yellow) when power was applied. When the ON button is pressed, the power LED turns green for roughly 8 seconds and then the power LED turns yellow again. Nothing else happens.
I checked many components (fuses, capacitor ESR, diodes, etc) on the main board and the master and slave inver

Main Board? Had issues for years, where I had to unplug once in order to get the tv to turn on. Then one day, it would not turn on. The TV shows a quick lightening of the screen like it is going to turn on, but nothing appears. It also clicks once or twice. Took to a repair shop and they diagnosed with main board failure and refused to fix due to lack of parts. Do you think it is the main board and where would I find one? I am pretty handy, do you think I could DIYthis job?
The fault must be due to a main board fault. Generally, it will be impossible to get this board repaired. A replacement must be done. Most of the parts in this board are not available by local electronic spare part market. After power ON, there sh ...

Panasonic hdtv pt-50lc14 will not turn on. When you turn it on the green light flashes and I hear some wierd noises coming from tv, like a dvd spinning twice, and then it goes away and nothing turns on. The replacement lamp warning has been coming on for the last year or so. Before I replace lamp, I want to be sure that is the problem.
How do I replace lamp if that is the problem?
I had tv for about 6 years.
Hello,I think the problem is certainly from the lamp because if the lamp lamp of a TV dies, it begins to flash green light and it won't turn on. This is also similar to a power problem. The only difference is that a power problem will fla ...

You will have to replace it. The reason the fuse is blowing can also be to X-sus board as the two sustain boards are capable of frying each other. They cost you about 170$ together. If you can get me the part numbers off the boards, along with any re ...

I have a Sanyo DLP 50747. When I turn it on It clicks off in about 10 seconds. I read online to try replacing the sub-power board(part# SJ-B10N2010A) and if that does not work then replace the power supply board (part #LJ41-05246A) both of which I purchased from Shopjimmy.com. I replaced both and it still does the same thing. Can anyone give me any other suggestions?

Hi, can you help me with this TV please.
Hi, I have a Olevia 232-T11 LCD TV. First my TV wouldn't turn and the blue light just stayed on. I replaced the power supply board and now my TV turns on and the screen lights up but I get no picture or sound. The slave backlight inverter board has a blue light when you turn the TV on but goes away shortly after. The screen stays on but I have no sound or can't control the channel, volume or source button. Please help.
If the tv is not coming on but there is no picture or sound then it is a 100% guarantee that its a problem with the audio/video main board of the tv. I am sure that replacing the same would resolve the problem. Please get me the part number that is p ...

Fixya tv I have a Samsung LCD TV. Model Number LN40B530P7FXZA. In January this year my TV picture went out and only had sound. I replace the power supply board and all was well. Well the same thing happen again but this time one of the fuses on the board has blown. I replaced the fuse and as soon as I plugged in the power cord it blew. I did this twice. Should I get another board or is it something else? Thanks.
It sounds that there should be a dead short circuit in the power supply board's circuit. If you are not familiar with\012electronics, do not attempt to repair. \012Whether you suffer fatal electric\012shock. Instead, conta ...
