Try to adjust the Vs down about 5-10V.

    Open the back cover and you'll see the Vs specification printed on the back of PDP panel. Vs is from the Power Supply board. Using a multimeter to monitor the Vs and reduce its value 5-10V below its spec. First try this simple way. If it does not work, you may need to replace the YSUS board of your tv.

Hi,
The problem is more or less with the LCD screen itself. The manufatcurer covers dead or burnt pixels.I would suggest contact Vizio Support on the following number

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.
