we have a 2015 cardinal and no problem. i'm making some assumptions here. I assume you are on 50 amp shore power. should be plenty of power. I'm also assuming the tv dims down due to lack of electrical power. do you have an ems system installed that can display amps being used? if so, how many amps are being used prior to the a/c switching on? after it switches on? is it possible that the a/c is using an abnormal amount of amps? but then why isn't the a/c circuit breaker tripping? can you measure the voltage of the 110 circuit that the tv is plugged into before the a/c comes on? after? is it dropping? even if these measurements showed that they tv is experiencing a voltage loss, that doesn't explain why? 50 amp should be more than enough power.

I cannot tell from your posting what you mean when you say you cannot watch TV when the A/C kicks in. Do you mean the TV powers off? Or do you mean you lose your signal? Are you watching off-air TV, or Cable, or Satellite? If from an antenna, you may have something going on with your A/C that is causing signal interference? Could there be a loose coax connection between the signal amplifier and the antenna?

What I meant was we can be watching TV everything is fine ...the A/C kicks on and there is static the picture gets distorted and freezes then it says no signal every so often the frozen picture pops back up when the air shuts off its still messed up but will eventually get back to normal

Robert,

Just a guess.... Possibly vibration from the AC unit, in relation to the antennae. Could it be the connection to your antennae is loose?

You might troubleshoot by running your cable direct from the campsite post or your antenna. . If that solves the problem, may have to run new cable thru the camper. Sounds like a shielding problem.

Is it just one A/C causing the problem, or both?

I agree that it sounds like a shielding problem with the antenna cable. You may be able to re-terminate the cable once you find the problem.

Sounds like you are missing an (Alt current) A/C filter. looks like a metal collar that goes around power cable for the tv. BUT maybe....
What I am wondering about is that the air conditioner and TV should be on separate Circuit Breakers.
Is the TV and Air/cond breakers next to each other in breaker panel.? The only place the two wirings come together is in the CB panel. Maybe the neutral side is loose. that the air conditioner is pulling the amps down on the TV circuit because if it was the 110 side it would trip CBs.
just a thought.

I had the opportunity to remove the bulkhead in my 3850RL basement to tighten down the water pump connections due to a slow leak. While in there, I started checking connections in general and found the Coax connections that I could see where all very loose, not even finger tight. I don't know that you can get to the TV antenna coax connection easily, other than climbing on the roof to see if the antenna one is exposed, and then the connection behind the on/off button for the amplifier, and finally the connection behind the TV. Of course there are probably a few splitters in the basement or in a wall somewhere if you have multiple TV outlets in your unit.


On my old bumper pull trailer, I had similar symptoms you note, and it ended up being a lose coax connection on the roof from the antenna.
