I just replaced the DLP chip and now the screen is white with black dots

The DLP chip is failing. There is no way to fix this except to replace the DMD (digital mirror device) chip. Contact Mitsubishi for repair centers.

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

White dots on your RPTV television are the result of the DLP chip being worn out. You can replace it very easily by buying a new DLP chip for just under $190 and installing the new chip. There is a very good forum over at fixyourDLP that offers tutorials for replacing the DLP.

White dot for DLP Projector TV is not because of the light buy. It is caused by aging DLP chip ( DMD Chip.) Your TV DLP Part should be the following image:

Check the post how to place it diy

If you focus the image on a screen up close to the projector and notice small rectangular black and white spots, then you have pixel failures.

If you get White or black dots all over the screen (DMD symptom)
If you get a pixilated picture (DMD Board)

the white dots (sometimes you get black ones too) are caused by a faulty DLP chip. you can find the replacement for your TV at the following website:

sound like you have a bad dlp chip. this happens to a lot of samsung dlp tvs. some of the mirrors are stuck. they can appear as black dots or white dots and it usually gets worse over time.

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,

If these dots are only seen when the picture is on I would look for the Optical Block to be causing it. Are the dots in the same place each time you turn it on?
