I have blue dots on the screen. I cleaned the glass on the projection bulb and the prizm but still have blue dots.


Your tv is an LCD projection one - in which the image is generated by 3 small LCD screens. The blue dots are pixels from the blue LCD that are dead - always fully open.The only fix is to replace the LCD panel and that is going to cost you around $300.

What does it mean by dead cells?


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.

Why are blue dots appearing on my Sony Flat screen tv. they seem to multiply every day.


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.

Sony a100 distortion dots - Im getting several


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. "

Probably the optics block. It needs to be replaced.

However, it looks like you're in luck. Sony will reimburse you.
