Sound but no picture
This seems to be a pretty technical forum, I hope this isn't too
simplistic of a question. My big-screen RCA TV suddenly displays just a black screen. Sound's OK. I've tried different inputs, both satellite and DVD, in three different input options - co-axial cable, RCA jacks (in video 1 and video 2 input jacks), but to no avail. The puzzling part is, when I change the volume, I see the volume bar on the screen. Plus, I can access the built-in menu for the TV. But I cannot see the satellite menu. Anyone have any thoughts as to how I can correct this? Or should I leave it to a repairman? Thanks in advance!

Closed caption and PIP malfunctions sometimes do things like this.
GemStar module also has been known for a variety of ills. In article , steveosmith@hotmail- dot-com.no-spam.invalid says...

Unplug the TV from wherever it gets it's AC for 2 minutes, and plug it back in. There is a 75% chance it will work ok. The only way to reset the system control to clear software glitches is by unplugging. If not, repair would be well beyond anyone unfamiliar with projection TVs. John |

John THAT'S WHAT YOU DO WITH MACINTOSH COMPUTERS, NOT TV SETS. |

Absolutely, unplug it to reset the system control. With all the
different manifestations of the Gemstar circuit in an RCA, many odd problems are easily fixed with a simple unplugging to reset any software glitches. Beyond that troubleshooting by a qualified technician will be required. |

The first thing is whats the model number on this. Second, I would call a repairman in to check it out for you if you don`t know the basic of tv repair because you maybe getting in over your head with this depending on the chassis number on it. |
