Question about Zenith P42W46X 42 in. Plasma EDTV

1 Answer

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

I heard a pop sound and screen went black but there is still sound. Open up the back and tested all fuses. Found 1 blown on the Z-Sustain board and all four capacitors look blown also. Replaced all four capacitors (Two on the the Y-Sustain board and Two on the Z-Sustain board) plus same type fuse. Closed everything up and now there's no sound and everytime I turn the tv on from standby red light it would go into amber light within 10sec and then green for 2sec then shut down. Any help would be greatly appreciated.

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.

PLASMA TVS DONT HAVE INVERTER CIRCUITS. YOU MOST LIKELY HAVE A Y-SUSTAIN BOARD FAILURE. IT IS THE BOARD TO THE LEFT LOOKING FROM THE BACK. THE LARGE ALUMINUM HEAT SINK LOCATED ON THE BOARD AND THE PART SCREWED TO IT WILL BE THE DEFECTIVE PART.

LG 50inch Plasma received loud sound then went black


I suggest you guys take your TV's into a repair shop like Sears or Best Buy... The main reason most plasmas go dark is because of decay, but I don't think this is the case. Because what you describe is similar to what happens in LCD's when their back light goes out. Although you can open up and repair the back light your self in a LCD, I would not advise you to do so for a Plasma, because of the hazardous chemicals used in the plasma display plus the fact that plasmas don't use back lighting. And 2 years is way to soon for decay to be a factor. So more than likely a circuit shorted out and the TV has to be opened up to be repaired.

replace the sustainer boards should correct this problem. New sustainer boards may cause red and green pixilation. If this happen, replace control board and TV is as good as new.

42 inch LG Plasma TV - Lost picture


Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.
