TV/Radio Switch not working 2018 Vista 29VE

Hi everyone. Discovered a new concern with my 2018 Vista 29VE over weekend. Not a huge deal but would like to figure out what might be the issue. In the outdoor TV compartment there is a TV/Radio switch for exterior speakers. It seems to work fine with the dash radio but could never get it to work with the TV. Tried changing inputs on the radio and messed around with the TV settings but had no joy. Have looked at the wiring diagrams Winnebago offers and there seems to be a relay/amplifier involved. For the life of me I can't comprehend where is little gem is physically located in the coach from the diagram. It appears to be somewhere near the bed platform but I don't want to start indiscriminately tearing things apart looking for it. Any insight on this model and troubleshooting ideas would be greatly appreciated.

Check all of the plugs into the back of the TV set. There is one that handles sound, can't remember if it is the HDMI, or a separate one. They come loose sometimes, and just securing plugging them back in has worked for me in the past. The cable bundle on ours is a bit short, and they pull out sometimes.
