Cleaning Optical Block


Sorry to be teh bearer of bad news, but the optical block (light engine) can not be dis-asembled outside of a cleanroom. You can remove the rear cover of the set and clean the mirrors and glass. That may help, but usually these typesd of symptoms are an indication that the light engine is starting to fail. The light engine can be replaced by you if you feel comfortable. The part is still available.

Keep us posted.

Take off the back, and take out screws holding in the light engine. Look at new light engine, and the old one you will have to take off a couple of things that your new engine wont come with. It is very easy to change. Any questions please ask.

I have the same problem. The repair guy said it's the optical engine and you may as well replace the set as pay for the repair. First time I'm glad I bought the extended warranty. That's another story. Zonieal
