I called Sony Customer Service and they put me with Executive committee, you have to be firm, we said the light engine is the major component of the TV comparible to a picture tube, which is warranty'd for 2 years on a regular TV. They were great, we got our TV fixed in less than 2 weeks. Hope this helps

It is either a lamp sensor problem or a lamp driver problem.

Dark smudges/spots on my HDTV screen


The model indicated here Sony Grand WEGA KDF-50WE655 is a LCD rear projection and rarely if ever requires cleaning.

If black spots or such are gradually appearing the issue on this model is the optical light engine.

Set uses a LCD engine which the lamp shines directly into and heat from that very hot lamp can damage sensitive baffles inside the engine.

I would suggest also you contact Sony as they have on several models extended the warranty for this kind of issue---Engine is very expensive part and several of these Sony sets were involved in a class action lawsuit--hence they are dealing with them.

Do not take no for an answer if you want them to help you---the hinge that is sqeeks gets oiled...........

It's probably the famous optical block problem. I had the same problem, mine were blue, but looked like magnet spots too.

You may want to have the optical block checked out. Usually when you see spots or blotches of color it's due to a malfunction of the Opt. Block assembly.
