Question about Mitsubishi Televison & Video
Need help getting the spots to disappear
This is common--a few spots and then more over time can happen--damage to the optical light engine display----Major part and major labor.

It could be only dust building up and it needs a good cleaning or it could be the DMD board is going bad and needs to be replaced.

You need to replace the "light engine". This is very very difficult. You need to take it to a repair shop. But this will be very expensive. Around $1,000.00

SOURCE: Blue spots on the screen.
Assuming that an alignment tool is not your problem, if the blue spots are regularly arranged in rows and
columns, I would have to say that the blue filter of your three tube (red blue green) array needs service.

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.
