If the lamp comes on, that's a good Now listen for the apparent fan noise. Your TV should have two fans inside...one close to the lamp, and the other one at the other end of the TV. The color wheel is in a tunnel, right where the lamp output is directed. If the noise is coming from in there, you might have a bad color wheel. The bearings migth be bad and it might have chipped off a color or two...it might be stuck! At any rate, that leads to more investigation. give these suggestions a try first! Tom,

The color wheel can cause the TV not to turn on...it can cause discoloration...it can cause flickering and fading images...it can also cause a double image effect. But what you're describing, 80% of our screen going black seens to be a optical block problem. I don't want to get technical here because there is no easy fix for it :( I would approach Samsung about this problem directly. They have always been reasonable on factory defects and this sure sounds like one...even if your warranty is out a few months (its the warranty two years anyway?). Optical Light Engine is going to cost you well over $1,000 new...contact Samsung! Tom,
