There is a very easy way to decide if it is your Digital board or your light engine. When you turn off your TV and the logo come up, are the spots still there? If they are then your light engine is bad and needs to be replaced. If they go away, then your digital board needs to be replaced. And yes you can get that board from just about anywhere.

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.
