Red dots on dark back ground screen


for this symptom (over diffusion) the voltage for Vsetup has to be decreased, or for opposite (under diffusion) has to be increased. These would be on your sustain board Y. Make very SMALL adjustment, as this can be very touchy potentiometer. There is a sticker on back of panel that will have all the voltages for Vs, Va, Ve, Vscan; these are very important, have to be spot on.

What is the white dots going from left to righ on my Plasma tv?


Most Plasma Tvs eventually develop this problem. This is called "diffusion" and it is a fault that occurs in the Panel of the tv. In most cases it can be fixed by adjusting the V-scan alignment settings but in some cases you may have to replace the panel. Hope for the best and contact Panasonic support so that they will help you fix the issue.

Plasma tv has little red dots in the black


This problem (known as sparkles) can be cured by adjusting the ramp control on the Y-Sustain board. If this does not cure the dots then there is a software remedy for the control board which an LG repair centre could fix. Failing that a replacement board is required. The orbitor & whitewash are like screen savers to help to prevent a screen burn from a permanently displayed image.
