Re: Plasma Screen not working only sound

It might be one of the power supplies. There are three in this model. One for the sound, one for the video, and one for the computer components. The video power supply is probably shot. They cost about $200 a peice from LG. If there was a "pop" sound when the video stoped, then it might be one of the circuit boards in the back. Yet again, they are three, each costing around $200 from LG.

If the Vs and Va voltages to plasma panel is abnormal, this could happen. Check these voltages. Both these voltages are critical, and should match exactly the same as marked on silk screen at the back of the display panel. If you wish to get some details; check the site linked here.

Z-sus boards are the weakpoint on those models of Plasmas. But If you eventually loose your picture entirely, but retain sound it is even more likely your culprit.

There are 4 or 5 ribbon cables on the bottom or on one side, they control part of the plasma screen. Check the ribbon cable near the black lines. Unplug the ribbon cable and look for black chips on the underside of it, I think they say 100 on them, you need to resolder both ends on each chip. Should fix the black line issue.

Some of these have a 4 pin test on the control board that you can jump with solder to get test pattern. If you get it to do that then these boards maybe good and would replace the control board. if nothing happens, then
the upper & lower drive also the Ysus and Zsus boards all at the same time.
last could be a defective panel.

P42W46X Zenith Plasma - No Picture - Mostly Yellow on screen

Mine looks like too, but the line running across isn't on my set, picture looks like this, and the sound works fine. I took the tuner board all the way out and turned the set on and it did the same thing, then I unplugged the top wire on the board next to the tuner board and the screen went black. plugged it back in and the screen came back with the scrambled picture. Anyone know why? Bad mainboard maybe? the left of the tuner board?
