been useing a lg 50px5d for about 6 months now with a cable card and all seemed ok till a few days ago.the best way to discribe it is tiny dots on the screen...THERE RED...there very small...can see it if i move close to the screen...with a very close look i can see what are the pixels and these tiny red dots are within them..they kind of like flash on and off all over the screen.. tryed reconnecting the cc and cable line input and ran a channel scan even reset all the settings to normal out of the box..dont know if this is a reception problem or not being i get these red dots on all input settings dvd, video,cable etc...has anyone ever hear about these red dots (snow???)and what i should try to correct it...or is my screen on the way out...thanks
