For a few chassis types of the Panasonic DLP projection sets (not the CRT tube type), this issue is resolved with a firmware upgrade on the light engine. Your firmware somehow got corrupted and it will degrade with time to even more spots. The new software is robust and self-correcting and have never been back to the homes where the upgrade was done. Many times, power outages, static discharge, or killing the AC power until the set turns itself COMPLETELY OFF (such as plugging the power cord into a cable box with the AC outlet set to "switched"), can cause this.

The fix provided by the factory (usually for free) and should be done by an authorized service center. Don't try this yourself... Simply call the Panasonic helpline, explain the problem, ask politely for a
concession form for repair and the recommended servicer in your area.

MOST IMPORTANT!!! Call ONLY a factory authorized service center! Anyone who asks for money to fix your set is jerking you around and don't use them. I've met people suckered into buying a new light engine to repair their set...

Purple lines scrolling, green in the middle, blinking on and off


Time for a new TV... Unless your really really really attached to that TV your going to spend more money on it then its worth to try and troubleshoot and repair it. Most of the TV's that come across my bench for repair that have developed lines and color splotches go into the recycling dumpster, they just aren't worth the time to repair as it usually comes down to a bad board or components that just can't be obtained to repair it. What most people don't realize is that once a tv is a couple years old there just isn't service parts for them anymore. The manufacturer keeps parts available until the warranty period is up on a model then its done for.

Sony trinitron 32 " purple area on screen


Check any magnatic device near TV which causes purple color on screen. That device can be Speaker, Electronic toy, Watch like that carring piece of magnet inside. Remove that device and turn OFF your TV for half a hour, then power again. Hope the color will be fine n normal on entire screen.

Light green and pink spots on my hd tv!!!


Tiny particles of dust on the light engine lens can cause this (and was a service call for me about a month ago), or possibly the expensive light engine.
