Please give more details.
Is this happening during all inputs, or only when watching cable/satellite/certain channels/etc.? Be detailed if possible.
Also, is it anything similar to the following video depicting something similar in description, anyway-
Good evening everyone:
I have a five year old 42" Panasonic plasma TV (model TH-42PX75U). Since a few weeks, I am experiencing red pixeled artifacts on the screen (like swarms flickering across the screen). Sometimes they are gone, but they always come back. It seems to be getting worse as of the last couple of days.
What's going on here - is my TV going to the dogs? A bad chip perhaps? Is this something I can fix myself?
The warranty's long expired, and I can't afford to buy a new TV right now.
