Purple and Blue Spots on Screen on Mitsubishi WD52527 52 Inch HDTV
Does anyone know why there are purple and blue spots on my screen?
Is it a cleaning issue or worse!?! The blue spots are in the lower right hand corner in a half circle and the purple spots are scatterd thoughout in no particular pattern. Any help will be greatly appreciated!

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.
