I've noticed this issue mainly when playing video games in certain colors such as blue. When the screen pans horizontally the picture seems to break into really ugly vertical lines of differing contrast. I'm wondering is this a common issue with Plasmas? Is this something I've done, maybe image retention or something?
Also this ST30 has some green blobs at the top of the screen. I know this was a much talked about issue a couple of years ago. The TV is long since been out of warranty. Is there any fix to it from US Panasonic now?
