"Set Parental Control Pin" screen stuck on component setting on Samsung 42" Plasma hooked up to Cogeco cable. I suspect this might be something to do with the cable box? No idea... nothing happens when we try to enter the 4 digit code, pops up "not available". There's no picture, just this screen but there is sound from whatever channel it's meant to be on. Any thoughts? Samsung didn't have a clue.
