What is the symptom when you get white spots on screen?

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.

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.
