My samsung tv white lights popping up on monitor

The dots are most likley the optical Block ( light Engine ). The not powering up issue could be numerous items , have you tried accessing the self diganosis feature with the power indicator blinking an error code?

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

This problems is the tv Projection Light Engine design flaw with it IC chip.These problems happen to many models of it DLP tvs Big Screen 60 and up.Mitsubishi,Samsung,Sony,Toshiba all used the same IC chip on their 60 and up on their DLP tvs Big Screen.Tries make deal with Mitsubishi help u split the cost of repair the tv Projection Light Engine by replacing the IC chip or replaced the entire Projection Light Engine system.This problems is not new,been going on for a few years.Many people when on Youtube **** about this problems with white dots showing up on their tvs screens and multiplying rapidly.

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.

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:

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
