how about power indicator at the front panel does it have?. if none you will need to check for power supply failure. check for a blown fuse first.

solution
I think your problem maybe picture tube.
next try
At first test for you flyback transformer and A.C. transformer out put voltage.
Best get it checked at your local repair shop.

Hi

Thanks for using FixYa. As Plasma TV is a very hard working device so it produces lots of heat and around 75% issues in Plasmas are caused due to overheating. To start with you'll have to open the back of the unit and check for any bulged/bad capacitors on Y and Z-sus boards. As the sound is working fine so it seems that the power supply is fine, also check the control board for any bulged capacitors. You can click on this link to buy the parts. Please accept the solution if the issue is resolved or post a comment for further assistance.

Thanks

There is no voltage adjustment that will help this. The only voltage adjustments that will improve the picture si the VS and the VA voltages, and they will only need to be tweaked if you have red or green sparkles or small dots on the screen. This is a tough one because it could be either the panel(screen), the Y-sustain or X-sustain module, or the control pcb module. Some techs are replacing all 3 of these boards to be on the safe side, but that would be expensive. Without doing several tests and voltage checks, it would be impossible to say exactly where the problem is. If it's the panel then it probably won't be worth repairing.

did you check the board could be that issue check with a tech guy and verify that

This is a common problem on these plasma TV's. The problem resides in the high voltage boards known as the X and Y Sustain boards.. You can purchase them here for a very reasonable price:

The above link is to a Y-SUS board. The X-Sus board is often the 2nd cause of failure and can be found here:

To test which board is failing, you need to check voltage input to the YSUS board first... Input should be 120V from Power supply, output should be above 250V.. Do this test with XSUS disconnected. IF 250+V exists, then XSUS is damaged. If not, then the YSUS is the faulty part.
