Our 55" Samsung DLP television has white dots all over the screen. Day after day, more seems to appear.

I'm guessing you have a Samsung rear projection tv. This is a common problem on them and can be repaired by having the DLP chip replaced. Samsung is covering the cost to repair tis problem on certain models. You can call 1-800-samsung to find out if it is covered and the nearest service center.

Hi,
white dot is from a failure in the dlp chip. it controls 1000s of tiny mirrors which help make up your pix, when the mirrors get stuck a white dot appears. over time more will pop up. Probably in the $300-$500 range to have someone repair.

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.

your dlp ic is going bad and needs nto be replaced. some of the mirrors are getting stuck they will appear as black dots or white dots. it usually starts as one or two and will continue to get worse over time.

Yes if you replace the Light Engine,this is a very high dollar part! call UED for rebuilt price 1-800-648-6657

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.

If the white spots are appearing in different spots or "Moving" it is the DMD board beginning to fail. Samsung DLPs seem to have a lot of DMD board failures. I would expect it to completely fail in the next couple months.

If there are only a couple small white spots that never go away it could be a mirror that is seized on the chip, but it's far more likely that the DMD board is going bad.

Random dots or pixels failing on a DLP TV will be a bad DMD chip. This is a technician replace item only. The chip runs around 160 dollars list price. The part number will depend on which version the set uses and will be determined by the technician.

Are these dots moving with image or stationary under a moving image. This is a key identifier
