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.

It is definitely a bad optical block. Sony was offering an optical block replacement under warranty until June of this year, but it has ended now. Ballpark estimate is $700 to $1000 to have the optical block replaced.

What you probably have is a very well known problem with the optical block. As it covers the screen, it will turn everything else greenish/yellow.
The optical block is very commonly replaced and an expensive repair, but the extended warranty (in place for all these TV's regardless of purchase date) on these sets is expired or about to expire. I would urge you to call Sony (1.800.222.SONY) immediately to try to get assistance, and to see if the warranty is up on it.
Hope this helps you...

The repair isn't too complicated if you're comfortable working with a soldering iron. Sounds like one of the "guns" is shot. The chips that need replacing are attached to the heatsink on the convergence board. The reason for replacing both chips is if you're going to bother to take the board out and replace one bad chip, that is the best time to replace the other older chip. The link below is to step by step instructions including pictures of the repair. You can check it out to see if you want to try it. If not, the repair is expensive (between 250-400) depending on the repairman. Best of luck with your convergence problem.

That is a symptom of the light engine failing. that is the projector part of your TV where the lamp plugs in. Go to Sony's website to contact them and see if your model is still under extended warranty, if so they will help set up repair. If not it could cost several hundred dollars just for the engine plus labor. Good luck
