Question about Vizio Televison & Video
When there are daytime scenes, or bright scenes on tv picture seems ok...not quite perfect like it was though. Also up close you can see small lines of some sort....
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.

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.
