I have a 42" plasma TV from Panasonic. Every so often, I see red dots which become concentrated in certain areas of the screen. This can happen on any broadcasting station. I have no unshielded electronic devices near the plasma TV. The power cord is connected to a surge protector. What can be the cause of these red dots that appear on the plasma screen every so often? It is very annoying.
Thanks for any help or suggestions.
