Worked a charm on my 50" Samsung DLP. Read thread carefully as there are 2 different version of the DMD chip you will need to replace. I ended up fixing mine for less than $165!

SOURCE: Samsung DLP white spots

Are the spots fixed or do they move with the image? Verify that all venting is clean of dust. If the spots are fixed and upon close examination are a square shape, The device is overheating of failing. If the spots are moving with image it's a front end problem, and can be overheating as well.

SOURCE: White dots appearing on Samsung TV screen and multipling each day

It seems you might have an issue with the dmd board. Go to the menu, and if the dots still show on the menu, the issue definitely is with the dmd board but if they don't come up on the menu, the issue will be with the video board.

My Mitsubishi TV has a small white dot on the screen


This could be something on the lens or mirrors. you can open one or both porthole covers on the left or right side of TV to determine if this is the cause. You can look at the mirrors & lens to determine if a bug or dust has gotten on either part. Then clean.

HOWEVER, the most likely cause is the DLP chip. this causes white & or black dots. May start out as one or two, then multiply.

See the following website for the proper DLP chip for your Mitsubishi model#:

Own a Samsung DLP TV 42 inch and white dots have


The random whit dots you are seeing is more than not the DMD or million little mirrors board. The white spots represent some of the mirrors that are sticking in the on position. In that case they are always reflecting white light from the lamp. I don't concider the DMD board a do it yourself repair since on the older DLP set it requires mechanical alignment as well. The best thing to do is contact a techincian and see what they might charge to repair the TV for you. Please take a few moments to rate my answer...Thanks..

Samsung dlp white dot


If the white dot is on every picture and every input and stays there for a sec. after you press the power button to turn off the tv then suspect a stuck mirror in the DMD.

Have little white dot's on screen will changing


Highly unlikely the bulb could be at fault; it sounds a lot like a defective DLP chip. If you are not aware of how this device functions, it is an array of physical mirrors which can fail individually and cause the effect you are having. The bulb failing would cause a loss of the entire screen, not just a few points.
