    I am having mine serviced now. It is the Light Engine which is a very expensive part. Hope you are still under warranty.

    I had the blue spots about a year ago and pulled the front off and dusted with air fairly well they were still there but hardly noticeable. .. The blue spots are now coming back again.

    I called several technicians who all said it was the light engine, which was about a 1k repair

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.

I have a 55" Sony Wega HDTV rear projection television and it has developed purple pin size spots on the screen. It started with just one spot and quickly grew to hundreds of spots over a couple weeks....

You should do a regular cleaning maintenance to the air filter and exchange it regularly. Small dust particules may get into the internal projection module and those spots became visible.

Purple spots in the screen

I'd like you to try doing this, select the service menu, and if the spots are still there, it's an issue with the DMD Board but on the contrary it might be the Digital Video Board. If you're decided to purchase the board check discountdashmerchantdotcom they have pretty accesible prices and good service, the only thing is that they only offer warranty to service centers, but they're good :)

those are going to be dust spots on the LCD panels internal to the optical engine. i suggest that you take the screen off and take off the panel i nthe middle of the tv with 2 screws in it and there will be an area that has 3 metal fins covering thin orange ribbon cables. the 3 square objects at the end of those ribbon cables will be the LCD panels spray wiht air compressor unitl clean and that should greatly help your problem.
