When our bedroom LED lighting is on, we cant get any signal to our TV's as well. Turn off those bedroom lights and we are good to go with either of the TV's. Ours if definitely an RFI issue with the lighting in our bedroom only. I have gone thru our coach and tightened the coax connections. I think there is a flaky ground somewhere.
We were getting TV antenna reception, but no cable TV.
Danemayer helped us out at the Colorado Fall HOC Rally a couple of months back and we got the cable to work, but it still wasn't right.
I ended up removing every factory installed splitter , which was a tremendous help, but still was not getting a good cable signal to the living room TV.
I pulled the Fussion stereo/CD/DVD player out of the entertainment center and discovered one more splitter behind it.
This splitter went to the radio and back to the wall plate coax connection.
The instant I unplugged the radio coax from the splitter . . . immediate perfect cable to the living room TV.
I played around with this and determined that either the radio or the coax antenna connect to the radio is bad . . . so now have no radio in the trailer.
I was only pulling in one or two radio stations on it in my yard when I should have been pulling in at least 20 stations.
It is at the dealership getting warranty repairs done and hopefully they will get this hooked up the way it should be!
Bigger TV coming soon . . . this was the big TV in our previous 2013 Heartland Trail Runner.
By the way, our awning LED lights don't seem to affect our TV reception.
