SOURCE: white dots on sumsung plasma tv

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.

SOURCE: Samsung DLP HL-S4266W White dot problem

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.

SOURCE: i have white dots on the screen of my hsl4266wx/xaa?

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?

SOURCE: white dots all over screen

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

I believe it is the digital projection chip that is beginning to fail. Causing white and black spots to appear. To repair this may cost more than a new tv. If you want to attempt it yourself check out the above link. Hope this helps

White dot on my samsung DLP 42" screen


Hi,
white dot is from a failure in the dlp chip. it controls 1000s of tiny mirrors which help make up your pix, when the mirrors get stuck a white dot appears. over time more will pop up. Probably in the $300-$500 range to have someone repair.
