I have a 57" mitsubishi 1080 dlp tv and it has a white dot on the picturewhat is it and how to fix it.thanks terry

Nope,,,White dots, white snow or sparkling stars on your DLP TV mean only one thing - a worn out DMD chip. The white dot syndrome seems to happen when the DLP TVshave been in use anywhere from two to five years - usually when the warranty has expired
Certain brands seem more vulnerable than others to the white dot syndrome. Samsung and Mitsubishi DLP TVs have been plagued with the problems for several years now. Sony and JVC choose to take the TVs set off the market in response to complaints from disgruntled owners.
If you read the various forums offering solutions, you'll see customers being given quotes of $600 and upwards for solving the white spot syndrome or replacing the DMD DLP chip. Fortunately, there are companies offering the offering the DLP chip for under $230 if you want to fix it.

Hello. Please call Mitsubishi! Some models the DLP chip is covered under warranty, and all you have to do is pay labor costs, our shop charges $200.

Sounds like your DLP chi is faulty

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.

Thanks for using FixYa and for the great rating.

This is a known issue for that brand check your model number and see how much the part costs probably a DMD board.

Thanks,

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:

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..
