Fuzzy cable tv

**robshamblin** · 06-19-2020, 02:51 PM

Have a 2020 320MKS and all the TVs are fuzzy when hooked up to shore cable. Tested from shore with my coax direct to a tv and it is clear. When I hook up to coax connection on P&B panel (use RV wall connections) all 3 TVs fuzzy. The booster is OFF. Reading about testing all the lines but how if they are in the walls and floors ???? Since all 3 same fuzzy pic I think something specific is cause not a loose connection at each TV. Advice ??

Where you connect the shore coax cable, check behind that plate/wall to be sure the connection is snug. It could be loose.
Also check the fittings to be sure the fittings are connected and making correct contact.
I hope what I am trying to convey is clear.

The cable is connected to shore securely and I can connect directly to a tv and it is clear. But when i connect to the RV panel jack all the TVs in RV are fuzzy.

The coax cables screw onto the back side of the wall jacks, at the water area and inside the trailer and can be loose on the backsiide of the wall plate.
The cable TV coax goes into the booster along with the roof antenna coax, and then usually connects to closest TV, and feeds one or two other coax splitters to feed more TVs and stereo.
GD can give you a cable coax drawing by contacting them.

Don't know specifically about your model but on my 303rls, if I try to watch cable with the over-the-air signal booster on, it's snowy/static. On my model, the signal booster red button is behind the TV.
