mikechamb606,

A model number would have helped me diagnose your unit but because you say that you have white dots on the screen, and the unit is only 3 years old, I will go with what I believe your problem is. I am assuming that you do not have a CRT projection unit. I believe you have an lcd projection tv which is starting to have TFT panel failures. As they age they lose more and more pixels which show up as white dots. The only cure for this is a new optical engine. Cost could be on the order of $350 US. The replacement is not that difficult and can be done using my tip at http://www.fixya.com/support/r4251975-replace_dlp_light_engine which will walk you through the process as well as link you to the best place to get the parts you need.

The white dots/stars you are seeing is a failing DMD board. It is the board with the million little mirrors on it. The white dots are mirrors stuck in the on position always reflecting the white light from the lamp. The DMD board is a technician replaceable item and part number varies by model code. Please contact a local servicer to have them look at your TV so they can order the right part number for your DMD board. Please take a moment to rate my answer. Thanks....

it seems like you might have an issue with your dmd board. Go to the tv menu and if the dots also show there, the issue is with the dmd board, but if they don't, it's with the video board

Random dots or pixels failing on a DLP TV will be a bad DMD chip. This is a technician replace item only. The chip runs around 160 dollars list price. The part number will depend on which version the set uses and will be determined by the technician.

Samsung DLP Projection Tv white dots may caused by DLP Chip. Change a new DMD Chip 19106143W. The post show you how to replace it step by step.

Your chip should look like this:

Will need model number, but sounds like digi board problem
