A discolored Blob or blotchy pattern usually in the center of the screen. the problem is becoming all too common with Hitachi projection sets. What happens is that one of the lenses in the optical block (or light engine) starts to burn or discolor due to overheating because of a blocked air filter causing poor air (cooling) circulation. Nothing can be done when the damage is too far-gone except to replace the light engine-at a cost that makes it not worth repair. if the damage is minimal than to reduce further damage, the air filter should be replaced. The Light engine needs to be removed in order to replace the air filter

Have it checked by a tech it's worth the service call to know for sure

Blue and Pink spot on my Panasonic Projection LCD


Panasonic didn't release a 61" LC13, are you sure that you dont have a PT-61LCX65, 35 or 15. If your model ends with a 5, call 1-800-211-PANA (7262) to schedule service, they have a fix fuzzy the fuzzy colored spots they are covering under warranty.

Pink and Blue Spots


Sony guarantee the consumer to replace the optical block assembly for thousands of dollars in parts and labor every four years or when the pink and blue spots appear every time. Then replace the optical block assembly again and again every time the spots appear.
