Satellite Snowy Picture Problem

[Mr_Bill]

I have a perplexing problem with the satellite system in an '04 Journey.

The satellite receiver output goes into a control center as a video source. From the control center it can be directed as a source for 2 different TVs and a DVD/VCR.

When the front TV source is the bat-wing antenna, I get a perfect picture. With the DVD/VCR as the source I get a perfect picture.

When I push the button to use the satellite as the source for the front TV, I get a VERY snowy picture. It's really not usable.

Pushing the button to use the satellite as the source for the rear TV, we get a perfect picture on the rear TV.

I hooked the satellite receiver output directly to the front TV. Same result.. snowy picture.

I restored it to the original wiring configuration. Then I selected the DVD/VCR source as the satellite and the front TV source as the VCR...perfect picture.

Why would using the DVD/VCR in the loop "fix"� the picture quality when having the TV hooked directly to the receiver results in a snowy picture? Also, why would I have a bad picture on the front TV, and a great picture on the rear TV? I originally thought it might be interference from the receiver causing the snow in the picture because it is close to the TV. But, since I can get a great picture using the DVD/VCR in the loop, I don't think that is the problem.

Anyone seen this before, or, have any ideas?

It sounds like you either have a bad or mis-labeled switch box. Is this a "just now happened" thing - or has it always been that way?

Since I don't know exactly how your stuff is hooked up, I can't be more specific.

My Winegard imput selector box has been replaced twice for almost the same symptoms. Front TV good reception on satellite, rear TV bad. Rear TV reception good on batwing, front TV is bad.

I hope I understand what you are saying. We had a problem very similar. Turns out I did not have the correct channel selected on the TV. Somehow we were getting a weak signal. Kept punching buttons and finally something connected. I have no idea what I did, but I figured I just had wrong channel selected.
