Pixelated Bedroom TV 2022 Adventurer 36Z

[Scotty B]

Hi Folks:
The TV in the bedroom is more often pixelated than not - both over the air and cable.
We thought it was just problems with the signals we get - you know how bad campground cable can be - but have noticed that there are no issues with the lounge or out door TVs where we had good service.
My initial thought was a bad connection - I could barely reach the one attached to the TV and it is tight.
I now wonder if it is the TV itself. I can't remember if we have always had this problem, but it does seem to be getting worse.
I guess I could stream something to the TV and see what happens as a good check for that.
My question is does anyone know where the junction box would be that splits the input into three cables for the three TVs? The cable attachment for the rig is in the rear wet bay.
There is a junction box under the left side wardrobe and drawers, but it is for HDMI.
Also, anyone know how to get that TV off the mount?
Thanks very much! The wife watches most of her TV in the bedroom and is not happy with the situation!
Also - the TVs are the ones...

We don't get the best info for audio and TV but more general ideas, perhaps?
One drawing is general plans for different setups with different number and location of TV here:

You may be able to match what you have to one of these as a general idea?
Notice the color coding on the coax as a way to consider where the other end might be found?

Then if we go to the parts catalog here:
https://catalog3d.winnebagoind.com/menu/Parts.htm

We can drill down to get some info on where they may have put things? They do not do a good job of showing what an item does, though! In or out?
I spot a couple places you might want to know about?

One behind the Wally at front? I think you mentioned one in rear below the TV?


That is about all I see on the parts. But there may be some good info on getting the rear TV down?

Looks like there are screws along the top which one might use a long screwdriver to remove those and let the TV swivel forward and then lift up to come off a bracket at the bottom?
