This is a problem is usually on your Y sustain board. There are two adjustments for this in which an Oscilloscope is nessesary for the alignment. However, there are two other things that can cause this also. This is beyond your abilities if your not a tech. Sorry for the news, It's not a major repair but should be done by a qualified tech.

Its the DLP IC chip itself that is bad. The DMD board is where the chip resides but if you order a board, it will come without the chip. Its not cheap and the replacement is tricky because the DMD board must be removed and then an alignment of picture centering will be necessary.

Sounds like your panel is on its last legs so to speak.
Might be time to look into replacing the panel. Running a high contrast can lead to a shorter panel life which may cause the occurence of dead pixels.

If these dots are only seen when the picture is on I would look for the Optical Block to be causing it. Are the dots in the same place each time you turn it on?

this seems to be an issue either with your DMD board or with your Digital Video board... turn on the tv and go to the menu if the white dots appear on the menu the issue is with your DMD board but if they don't show on the menu, the issue would most probbaly be with your Digital Video board
