Don't bedeterred by the dating of this announcement, it is a manufacturing fault and they have been pr5etty good to a lot of people with the same problem.

Please rate my help++++Thanks for using FIXYA

You need to change the engine. Please take it to SONY service centre

The EEPROM needs to be reprogrammed. You should contact Panasonic customer care as they may fix this at no charge to you.

Do you have a center speaker near it? maybe move it, that is what I have done and it seems to have gotten better.

Sorry, but there is no cheap method of repair for this unless it is in warranty.

This TV will require replacement of the LCD Prism unit.

This Prism blocks and allows colors so that the 3 LCD images may be mixed to produce the final image you see on the screen. When this becomes damaged or defective, it leaks colors (light). This Color Leakage apears as spots on the screens.

Where you see the spots is where the specific spot on the prism that is leaking light, the specific color that is leaking also.

This parts cost alone is normally $500 to $1000 dollars but is usually replaced under warranty.

Good luck.....

This problem was probably there before, but you only noticed with the new "Brighter" bulb.

Turn down the Brightness and it will not be as noticeable. I am sure you only see this with bright images.....like white backgrounds and such

Good luck.....
