I got the red dots really bad on my toshiba 50hp66 after an hour or two of watching tv. I found out that if you open up the tv in the back on the left you will find two adjustment pots labelled Vsc and Vy. I took a sharpie and marked where the factory defaults were first. Then I adjusted the Vy pot down a little bit and the red spots were gone! My tv looks great again!

Dots on screen

The snowy dots and dots are typically from a poor signal going into the TV.

If there are colored pixels that stay lit all the time (like a red pixel and never goes away) and for any input, that’s called a stuck pixel.

A stuck pixel may be caused by a bad Y-Sustain, Y-drives, Z-sustain, and or a bad plasma panel.

Good Luck.

Red Dots

This is know as diffusion. You will need to locate the Vs adjustment inside the TV and vary it up and down by NO MORE THAN 10 volts. If this does not correct the problem then you will need to replace the Plasma panel.
