I have a 60" RCA RP that has been working great since '99. Yesterday I couldn't get a picture. I unplugged the source and plugged it into another set and it worked fine. So that eliminates the source. I can still get the internal menus from the RCA but nothing from an external source. I have tried svid, and both inputs. I am just looking for any ideas on what to look for. These things are very expensive to have someone come to your home to work on them. Thanks for any help you might give Jerry
