42" Plasma, no picture, sound


Hi:
The best possible solution to your problem is to replace both sustain boards at the same time, The X and Y sustain boards. LG tech support recommends replacing the digital board as well when replacing their boards, even during LG's tech training seminars they suggest you replace all major boards for continued viewing enjoyment. But in my experience you should replace the X systain also, but make sure the Y you replaced is still good.

I have no picture but i have sound any suggestions


Replace 6870QZE013C or 6871QYH053A (more likely).

The second is the Y-Sustain board, located to the left of your TV when looking from the back.

This is the one that usually burns and the fuse on it is likely shorted. Do not replace it, it will burn again.

My zenith plasma tv popped real loudlike a car backfiring and then the tv picture went black. power on green light wil turn on but it automatically cuts itself back off to the red light


There's an over current fault in the power supply or the Y-sustain convergence board. The loud pop was either a capacitor or pico-fuse breaking from excessive current overload. Sounds like 2 or 3 mosfets have shorted at the gate ends. Plasma TV's always have this problem because they generate too much heat and the components cant take the load conditions. Make your next TV an LCD...

To fix this problem have your local repair shop do it for you.....

any questions please ask.....

LG plasma have an amber light when turning on then green then red


After all the research I found out that the IC on the Z board is bad and new board was ordered and replaced. The plasma work fine after that and picture is excellent with the new board. This forum is great, without this I couldn't fix it myself. Thank you.

We were watching tv and all of a sudden we heard a


I had the same problem. We replaced the Y Sustain board. It was under $200 and not at all hard to do yourself. Remove the back of the tv. Make sure you watch what screw goes where. You will see the board on the left side. The number should be on the bottom right corner of the board. Just watch how you removed the board making small notes as to what goes where. Its really not that hard and you can save 600$ or more

LG "NO PICTURE" , IF FIX WILL RECUR? ,DID LG FIX DESIGN FLAW 42PC3D


I had same problem - no picture, but sound worked - LG 42PC3d - was two months past warranty, but LG agreed to fix it as a warranty call. Service guy was out within a week to replace the Z SUS(?) board. Works fine now. This must be a typical problem, as LG did fix it, even though the warranty had expired. Good luck.

Picture is snowy/dark


update: Well, we ended up calling the repair man and we had a bad Y-sustain board and also a bad Z-sustain board. According to the guy who fixed it, it was due to over use of the TV and using main power button instead of shutting off through the cable remote. 650.00 later and a few weeks later, we now have a fixed plasma. No real suggestions on how to get more life out of the new boards.
