YOU WILL NEED YOUR CORRECT MODEL#

Sounds like either a bad DLP chip, or dirty optics. If the "sand grains" seem to "multiply< then you DO have a bad dlp chip, some mirrors are "sticking".

Thats caused by the DLP chip. Unfortunately most Toshiba models will end up having to have both the DLP chip and the formatter board replaced at the same time to fix the issue where as other models only require replacing the DLP chip alone to fix the white dots issue

if you have a samsung, mitsubishi, toshiba etc DLP the white dots are caused by stuck mirrors on the dlp chip. so the dlp chip will need replacement

You are describing a damaged optical light engine or the display chip which is part of it (chip is about 200 plus a lot of labor)

Replace the DLP chip at cost between $160-$300 for the part and about two hours of your own time to do it.

This is a part of folk lore, the DLP display "chip" is not available from the company who made this (or for that matter any other brand) and even if it was you would need the $1,000 plus desoldering station to attempt its replacement.

What is your problem? dots? if that is it the answer is either buy a optical light engine or buy a new set.

Yes,this problems is the Light projection Engine.The chip is bad.This happen to many models of tvs in the industries.Sony,Samsung,Mishibishi and Toshiba they all use the same IC chip.Call Toshiba make kind of deal with them,help u replaced the chip or the Light Engine it self.This problems is not new many people went to You Tube **** about this problems.
