SOURCE: White spots on screen Need DMD
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.

SOURCE: We are having white dots
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.

Actually you must replace the DLP chip that is buried deep in the works of the tv. Unfortunately this can run into a nice lump of change. Do what I did. Perhaps you've heard the old addage
