How to fix my 65" toshiba white pixel problem


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

My toshiba 65hm167 turns off and on


May want to retire this set---the white dots are a problem in the Optical light engine this model uses and that is a very expensive part---it may or may not also be the on/off issue.

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.

I have white specks on screen toshiba 65 in DLP


White dots on a DLP mean that some of the tiny mirrors on the DMD board have failed and are stuck in the on posisiton and always reflecting the white light from the lamp. The DMD on this model is not available sepratley so the complete light engine needs to be replaced. The part number for the light engine is 75006693.

White dots on tv screen


The white dots that come and go could be what is called ignition noise. Caused by something in your residence or on the power line to your living area. You will have to do some tracking. Take a portable radio and tune it to the 550mhz, you will hear a crackle or buzz, tune to the loudest that the buzz/crackle can be heard. Walk around to see were the noise gets to be the loudest. If it gets weaker you are moving away from the source. The source could be a dimmer switch for lighting, or a loose connection on a receptcle, or in the panel box that supplies the residence. Worst case it could be entering from outside source. I have tracked ignition noise as far as two houses away that had a bad butter control on a refrigerator that was on the same power line that supplied the neighbor hood. There are so many things this day and age that could be causing your dots. Yours come and go, so you will have to track it when it is acually seen on your tv. Sounds like something on a timer like refrigerator, Furnace, etc.
