I just purchased an RCA 52inch big screen. When you turn on the set it has 2 snowy lines that run across the screen lf to rt. It also showes up on all the other sets in the house. Once you turn off the 52 inch it goes away on the other set also. I was told it was cable, but it only appears with the 52 inch set on???? If this tv isn't on all the other tv's are perfect...Any advise??????

Disconnect the cable connection from the RCA 52. Try a DVD player on the RCA 52. See if lines are present. If yes, RCA is junk. If no, the line interferance is cable related. A mixed signal is feeding back through the house coax. The culprit is usually a loose or poorly installed coax connector. Sometimes it's a bad set top cable box. Cable is a lousy signal source. Bad fittings, bad splitters, ingress of external commercial and private airborn radio signals mix with cable signals and become a common distortion throughout the house network.
Subscribe to a sat service for the RCA and ditch the cable connection. You will be shocked at the difference.
