I'm guessing you have a Samsung rear projection tv. This is a common problem on them and can be repaired by having the DLP chip replaced. Samsung is covering the cost to repair tis problem on certain models. You can call 1-800-samsung to find out if it is covered and the nearest service center.

3 white pixel dots on the screen, just replaced my bulb.


If the white pixel dots start to multiply then Problem will be in the DMD board or the Light Engine.

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.
