I have whit dots all over my tv how do you fix this problem


If the model number (Toshiba 65HM167) is correct the dots are a damaged Optical light engine.

These early units were DLP but had a 1/4 of a million micro mirrors in the optical unit--if they do not open and close correctly you get dots---seen some with 15 or more dots.

Little white dots in tv modle# wdt657 what are they how can i get them off


Your TV is DLP projection TV. DLP is Digital Light Processing. Digitally processed light coming out of DMD (Digital Micro mirror Device) is projected on the TV screen. This DMD is made of thousands of tiny mirrors & the size is about 0.7 inch. These mirrors are fixed with tiny hinges for its movement. They reflect light as per processed signal. DLP is invented by Texas Instruments. When there are dots on the screen, that means the tiny mirrors representing the dots are stuck in its position. If the dots are few & the viewing is bearable, just leave as it is. If the dots are more than bearable then you will have replace the DMD chip which is quite costly.

I have blue dots on the screen. I cleaned the glass on the projection bulb and the prizm but still have blue dots.


Your tv is an LCD projection one - in which the image is generated by 3 small LCD screens. The blue dots are pixels from the blue LCD that are dead - always fully open.The only fix is to replace the LCD panel and that is going to cost you around $300.

White dots


There might be an issue either with your DMD board or your Video board, with the tv on, go to the menu, and if those white dots are still there the issue would be with your DMD board but if those dots magically don't show up on the menu, the issue would be with your Video board
