    Optoma HD66 I know it is just dust on the chip but I can't seem to figure out how to get to it. I have all the tools to clean it properly as I am both an electronics tech and professional photgrapher. Used to cleaning Cmos an CCcd in digital cameras.

    In my experience the chip is normally bad. The mirrors quit moving and it makes white or black pixels. I've only wokreded on mitsubishis. They are deep in the machine below the main board with a heat sink holding them in.

    I've only done Mitsubishi and the chips had to be replaced as the mirrors were bad they were located under the main board right by the back of the lens behind a heat sink.

Vivtek d510 projector has black and white spots covering 1/3 of projected image


The DLP Chip is failing .The DLP or Digital Light Projection Chip contains up to 8 million tiny microscopic mirrors that tilt to project a digital image onto the screen. These mirrors are failing causing light and dark spots to appear.Unfortunately fixing this projector is probably going to cost more than buying a new one. Hope this helps.

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

White spots


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

Bright white spots on mitsubishi wd-73833 I just replaced the lamp and now these bright white spots have started to appear!


This unit uses a DLP (digital light processor) chip and if this starts to fail then you will get spots appearing on the screen. The DLP chip will need to be replaced.

Spotty tv


DLP/mirror chip is going bad. A common problem on Sammy TVs after 2-3 years. Chip is user replaceable (try samsungparts.com or ebay) for about $150-200. Sammy was (last year) repairing the DLP White Spot problem for free. You MUST talk to ECR (executive customer service) to even think about getting that consideration--forget the standard CS people. Don't know if they are still covering this out of warranty in 2010.

Had one last week and now there are 6. they are


Hi,

You get white spots inside the samsung DLP tv due to bad Digital Micromiror Device , or bad DMD board .

What is actually the problem is the DMV chip connected to this board . Inside this chip are 3 million tiny mirrors ,and when they physically get stuck , they either show black or white instead of a color
This is well know problem with SAMSUNG DLP...

The DMD chip is failing.If not under warranty expect to pay a few hundred to several hundred to get it fixed

The mirrors on the DLP chip are slowly sticking either fully open (white) or fully closed (black). The part that contains the DLP chip is the Light Engine. It is the most expensive part of the TV.Only the Samsung TVs has this issue.

Replacing the DLP chip and the micro mirror would solve this issue...

Pleaserate this solution,

White spots on screen and growing every day


If these spots are small, they are likely the visual effect of a failing DLP chip. When some of the tiny mirrored surfaces on the chip stop moving, this is the result. This is not something you can fix yourself. A Samsung authorized service center will charge $400-$500 to replace it for you.
