SOURCE: May a pop noise, now no picture but has sound. it

Sounds like the Invertor for the backlights has blown. if you are lucky and it is just the invertor blown it could cost £50-£150 for a new invertor board, but if you are unlucky then the backlights themselfs have blown too which means the TV is beyond economic repair.

Screen flickers, on all channel's the tv is 5 years old

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.

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.

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.

I have a 50" zenith 10 months i can hear how can i fix this

If the unit is only 10 months old, it should still be under manufacturer's warranty. Call and request warranty service. DO NOT open up the unit as that would void the warranty.

Keep us posted on what is found.

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.
hope this helps. p/n are on all the boards.

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.

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?
