Colorful Dots I'll get right to the point. After my Sony plasma is on for about an hour I start to get colorful pixel dots appearing on the screen. They go away after having the plasma powered down for about an hour or two. But they do come back. It almost appears to me like static on old t.v. sets, but the dots are colorful and only appear in small portions. Called the repairman and he scratched his head and said he will get back to me....four months later here I am. Please help, I live in a small community with limited help.

I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.

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.

Sounds like a stuck pixel.

If the dots are tiny, those are probably dead pixels. The circuitry that drives them is probably degrading over time for some reason. It's obviously defective, dead pixels happens a lot with LCD screens. I would hope it would be covered by warranty, because the only way to fix dead pixels is replacing the screen.

If these are single pixels on the LCD screen, they are normal. From pg. 8 of the user's guide:

"The LCD monitor is manufactured using extremely high-precision technology so over 99.99% of the pixels are operational for effective use. However, there may be some tiny black points and/or bright points (white, red, blue or green in color) that constantly appear on the LCD monitor. These points are normal in the manufacturing process and do not affect the images in any way. "

This may also be helpful.

"images may trail across the LCD monitor in a cold location. This is not a malfunction. When turning on the camera in a cold location, the LCD monitor may become temporarily dark. "
