I am posting this here because the "Calibration Guys" usually post here and might have a better idea than the people in the RP thread.

I have a Panasonic PT-50LC13, that I have had for about 3 years. Over the last year or so the corners are getting greener and greener. You really notice it on an a white screen. Hockey games look like there is some kind of light green fungus growing on the ice. It is starting to drive me crazy!

I don't know much about the technology so I thought I would ask if there was something I could do to correct this or if anyone knows why this is happening. Aside from this issue the picture looks great!

Thanks

It's either a side effect of the bulb aging or something in the light engine.
