Thanks to all. Info was very helpful and problem is resolved.
The orange cable connection on input from outside, (From comments below I think that this is called the UDC - but not sure) goes to back of unit to supply LR tv only.
As per advise below I removed a few bolts on under floor of entertainment slide out
There was two connections going up to tv. One being the antenna, the other was the orange cable coming directly from front
I tightened conector and .... Bingo .... Dish signal appeared on tv
Weather the issue was due to a poor tightening of connector at factory, or corrosion due to time, is unknown. As mentioned before this camper was purchased new one year ago, but had been on a dealer lot for one year also.
Conclusion - Easy to fix once location of connectors were found
Again .... Thank you everyone for the ideas that saved me hours of work, thus giving me more time to enjoy the campground
Regards
Vic
It could be a barrel connection is not attached or not tight. There is likely one in the underbelly about where the entertainment slide is located. Follow the wiring harness under the slide where it enters the frame, and remove the screws in the underbelly material there so you can try to locate it.
Cables are run in the frame, and in the slide, while they are apart. When the slide is installed into the rig, they are supposed to make the connection for these cables. Sometimes they don't get tight, or don't get done at all. We've seen this before on the forum.
