Mark,
It may be that one of the PCB boards has gone bad. Usually that symptom isn't an indication of the actual glass panel.

I have owned a Samsung HS-S4253 42" plasma TV for a little over two years now. Within the past six months or so it's been exhibiting a condition that seems to be growing worse and worse. That is, it displays a brilliant, almost "fluorescent", blue/purple, snow-like, sparkling coloration over certain colors/images.
It generally starts after the TV has been on for a couple of hours, and appears predominantly in the lower right quadrant of the screen. It mostly appears in two particular instances: (1) over images whose color ought to be bright white, and (2) where a high-contrast image just previously was showing (for instance, using the TV's menu, after the exiting the menu, the you can still make out a "ghost" of the menu's words/images in this sparkling bright blue/purple color.
Since the TV's out of warranty, I'm left to my own devices. If anyone has any insight into the cause of this problem, or any DIY fixes, I'd love to hear them before I go out of pocket for diagnosis/service/repair or buy an new TV.
Thanks in advance.
