You have the problem called "diffusion" errors, or some call it non-erasing pixels, etc.. You may be able to adjust the voltages to fix the issue. The 2 main voltages are VS and VA. The value they should be is listed on the back of the plasma panel. If one is off, then it could be the cause. Some manufacturers recommend turning up or down vs or va by 10% to fix this type of issue. Unfortunately, it can also be caused by many board in the tv.. power supply (where vs and va are generated) plus also the y and z drive boards, buffer boards, etc. If they are across the whole screen, suspect the power board and Y board most likely. I can talk you through all the adjustments but you will need a dc voltmeter capable of handling 250v. Let me know your skill level and we can fix this together.

This is going to be either a voltage adjustment or a faulty control board and/or Y sustain board.

You need to have a qualified technician check the voltages on these boards to determine if they need to be adjusted or else (if the voltages are fine) these boards will need to be replaced.

That is called diffusion. that can be adjusted out in most cases by adjusting the y sustain pcb but can also be the main pcb, the logic pcb and panel itself but not likely

Either the TCON board or the LCD panel has failed. Start by replacing the TCON board. If the problem persists, the panel is bad and the cost to replace it would be too high.

Hello, why does my plasma tv have thousands of red and green flashing dots all over the dark parts of screen after it has been on for roughly half an hour? if i turn tv off for a while then turn back on...


I had a similar problem but mine was just red specks that showed up in dark scenes. I opened up my plasma and found the adjustment pots that are labeled Vsc, Vy. I then marked the factory default with a sharpie first. Then I lowered the Vy a little and my red specks disappeared. Now my tv looks awsome again like it was new.

I keep geting avery fuzzy pic


this is a low resolution camera, so its results may appear fuzzy, escesially if viewed on a higher resolution display/device.
try this: set the camera on a stationary surface and take a picture of a static scene, taking care not to move the camera at all while it captures the image. if this looks better than the photos in question then the issue is camera motion ( or available light or motion in the scene) while taking pictures. if it is similar to others then probably the low resolution is not sufficient for your expectations/needs.
