Its the DLP IC chip itself that is bad. The DMD board is where the chip resides but if you order a board, it will come without the chip. Its not cheap and the replacement is tricky because the DMD board must be removed and then an alignment of picture centering will be necessary.

This is something of an urban myth....The "DMD chip" is actually the LCD display IC for the set; yes I have seen some listed on EBAY---still a myth----they are replaced (when a light engine is rebuilt in a space age lab or environment) under exacting conditions----if positioned a micron off in any direction picture will be tilted in some way---this is also not like changing spark plugs in a car, if you have a optical engine issue like spots etc, either get a rebuilt engine from Mitsubishi or buy a new set.

They usually require some parts for old engine (mounting brackets etc) be installed on new or rebuilt engine.

I did see the "chip" for another model listed on ebay today.(100.00 PLUS)

I understand the engine is expensive, I replaced a lot of them when the sets were in warranty---more Mitsubishi than any other brand with Samsung a distant second.

I am sure Mitsubishi does not offer the part for sale--they want to sell a tested rebuilt engine only.

I wish you luck but have little hope you will find a "part" other than the whole engine.

We are having white dots appearing on our Mitsubishi DLP 65 inch television, approx. 3 years old. It looks like a constellation is appearing. New dot every day.


That means you need to replace the Optical Unit Block/Light Engine.Dmd board has been known to cause this also, but most of the companys replace Dmd and optical unit.

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.

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..

This could actually be an issue with either your DMD board or your Video board. With the TV on, select your menu, if the white dots are still there, the issue will be with the DMD board, but if they don't appear on the menu, the issue would be with the Video board.

White dots all over screen


this seems to be an issue either with your DMD board or with your Digital Video board... turn on the tv and go to the menu if the white dots appear on the menu the issue is with your DMD board but if they don't show on the menu, the issue would most probbaly be with your Digital Video board
