Sony TVs has an Optical Block issue. If there is an issue with the optical block, then there will be green, blue patches or tint on the TV display. Try resetting the TV to the factory settings and try Power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then TV may require service. You can contact the Customer relations team and check for the available options. Sony had repaired free of cost for such issues. Hence, contact the customer relations.

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.
