Question about LG Televison & Video

1 Answer

We've had our LG plasma for only 3 years now without a problem. Today, out of the blue, the screen went crazy, couldn't see any picture, it was more like static. My husband said the tv has been giving out a 'slight burning smell" verus just the heat from the top of screen. We've tried everything, unplugging everything, reconnecting it, leaving it off, ...but everytime we turn it on we just see "moving static" in differant colour across the screen. Sorry for the lack of technical terms....i'm a woman...

You will have to do real in-depth troubleshooting, I would suggest you to download the LG Plasma TV training manuals and do some reading, look at my link below.
It may have burnt components in the power supply, Z and Y SUSTAIN boards, blown fuses and caps. It will not be an easy job for home DIY repair.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

My LG 42pc1DV has sound normal but picture just died and is blacl, before this happened I had a lot of green pixels that only showed up across screen on dark pictures, 4 year old and just out of warrenty


Either your Y sustain board went out or your upper and lower Y buffer boards went out. Worst case scenario is your panel went out. But you won't know without replacing the other boards first.

42 inch LG Plasma TV - Lost picture


Hi , I recently had the same problem which I was determined to fix . So I did a few weeks of research to find that it was the Y SUS board which burns out. I'm sure you realized that the TV gets hot. Personally I think this is why. circuit boards don't like heat and I've learned that the cooling fans are a joke. I replaced the board and got my picture back. I proved the fan theory because after the screen started to act up. I placed a cooling fan near the vent holes on top and the problem cleared right up,It also helps if you lower the brightness which helps out on the heat situation.I will soon be adding a fan with a temp. sensor. This shoud help if your screen has lines when you initially turn the cool TV on.then I have Some other costless solutions. Hope this helped these are great TV's and like our cars we maintain them not throw them away..................................Mr Wiseman

LG PLASMA TV WITH COLOURED LINES OVER SCREEN


If the Video (Picture/Pix) is gone but you can hear the Audio (sound), then it could mean the YSUS PCB Assembly is gone/kaput/finish. Can replace the PCB, not repair the PCB due to timing circuitry involve. Cost maybe roughly $500 depending where you located. The PCB is located on the left hand side of your TV when you are facing the back (Back open). Might find 3-4 brown flex membrane connecting to the plasma panel. The PCB has a silver or black aluminum heatsink (big) on it.
Good Luck.

I'm guessing this is a problem on the Y-SUS PCB or the Control PCB. Call LG and they will find you a servicer. Most LG Plasmas have 2 year warranties and they are covered in your home. It kinda sucks but it is better now than after your warranty expires this repair would cost several hundred dollars.
