Your screen is bad or you have an alignment issue. Do you have a convergence feature in the menu or on the tv? Try it. If not, you need a repair. Contact the manufacturer for and authorized servicer.

Dark picture on wega lcd


Yes, if this TV has a bulb it is likely to be the bulb.

I am not familiar with this exact model, but other LCD Projection TV will show dim picture after some time. Expected life of the lamps is about 2yrs. After 2yrs the picture will become dim. After 5yrs I am suprised it is even working.

Dirt doesn't cause this problem unless your are a smoker or have the unit "literally" outside. DO NOT try to clean it or let someone tell you to do it because it will cause more problems than it fixes.

Its blue LCD mounted in light engine (optical block) and requires replacement.
Before, the solution was complete light engine replacement but now Sony Service Center will replace blue LCD only to fix it to reduce your repair cost.

3LCD Projection TV 2.5 years old displaying blue hue/blobs


I would first try a new lamp. If the reflector portion of the lamp has any defects, it could show up this way as the light would not be uniform. The next possibility is a defective light engine. The engine portion if not field repairable and would need to be replaced. Try the lamp first and let us know what happens.
