Main TV is SNOWY when bedroom TV is on

We have a 2016, 37 foot Cougar 5th wheel. Whenever someone is watching TV in the bedroom, the main TV in the coach is very snowy. When the bedroom TV is off, the main TV looks great.

I'll restrict my comments to using CABLE TV as opposed to the antennae.

I'm not sure how the wiring is run in my unit. When I hook the campground cable to my RV, it appears as if the cable is run to a Winegard Sensor Pro unit in the bedroom. From that Winegard unit, a Cable runs directly to my bedroom TV. It seems like another cable runs to the main TV. I checked the cable connections and they seem tight.

I'm wondering why my main TV would be so snowy ONLY when I'm using my bedroom TV?

Any thoughts?

You might check to see if your booster for antenna is on that will cause interference.

The booster must be "on" for antenna, "off" for cable, go to each tvs setup menu to change from "antenna" to "cable" & a "channel scan" must be done to each tv every time you switch signal inputs &/or change locations.
There's also splitters somewhere that may have loose connections or miswired.
If you have the new fangled Key Tv then pay no attention to the above & someone else will have to try & help.

As I said, I have a Winegard Sensor Pro. The cable from the campground comes into this Winegard unit, and then gets distributed to the 2 TV's from that point. According to the manual, if I select "CABLE" on the Winegard unit, the signal bypasses any of the Wingard circuitry and goes directly to the 2 TVs.

Both of my TVs are "smart." I tell each of them to look for a CABLE signal (as opposed to an antennae signal). The main cabin TV looks great until I turn on the bedroom TV. When I do that, the main cabin TV looks very snowy.

I don't get it.

Have you considered running a spare coax cable from the bedroom TV to the main TV to troubleshoot whether it's the signal amplitude causing the problem or a wiring issue in the Wingard cable splitter/amplifier switch plate???

You "could have" (as an example) a loose connection/short center wire at the trailer cable connector input fixture and there's enough signal to power one TV, but not enough to provide a "split signal" to the second TV. That's just one possibility out of many, but I'd first rule out the Wingard system with a "temporary bypass cable" to the second TV.

I guess I'll need a splitter to do that, right?

Yes, a splitter at the Winegard output to the bedroom TV, split from there to the main TV, turn them both on and see if the signal is strong enough to drive both sets.

Also, make sure the cables are connected to the right ports in the Winegard. If you have one of the outputs swapped with the input, it might present this symptom.

Also wouldn't hurt to make sure the connectors on the cables are installed properly too. Couldn't hurt.
