The model of the TV is a KDS-55E2000, not sure if that makes much of a difference.
You probably mean KDF-55E2000. Huge difference. No color wheel, this is not a DLP, it's a 3-LCD rear projection. I suspect the problem is that the light engine is going as happens to most of these. There's a whole website put together by one of our posters dedicated to the problem: http://sites.google.com/site/sonylcd...v-opticalblock
A picture of the tv showing a white screen would be more informative, but it's likely the LCD panel in the blue path or the blue input polarizing filter.
So I briefly read that site, and while informative of the actual problem it doesn't really offer remedy for my particular situation. Is a new rebuilt light engine available for purchase, and if so is it an easy replacement?
I'm an IT tech by trade and work on sensitive electronic equipment all the time, as well I had a Samsung DLP back in the day which required a new power ballast and bulb, admittedly those are two very easy fixes.
