I have had the Pioneer 503CMX for quite awhile without any major problems, other than the power supply that was replaced. I turned the plasma on a day ago and have an issue. Quite a few pixels are blinking, some are staying on for awhile before blinking. Probably a hundred or more pixels, too many to count. It is on all inputs. I am using RGB, Component, and composite and see this issue over all of them. I turned the tv on and off quite a few times, and the issue was gone. However I turned the tv on again this morning and there was the problem again. Any idea what would cause this? It is out of warranty, but I am hoping it is something that can be fixed.

I have read other threads talking about green pixels, and that is exactly what these are, as well as blue. Has anyone had any luck finding out what is causing this?
