Electrical-sat controller and bed inflate-no power

I haven't removed the cosmetic panels to see behind. I have the controller that I push the power on button and that is obviously visible. It has the power cord and the hard wired to the dish wires. I have checked all the plug in to outlets and none are dedicated to the controller. It is all warranty so back it goes tomorrow. Unfortunately it is Camping World that has one good tech and he is getting worn out. If I get the time I will remove a panel and check behind. Now I know what to look for. Thanks.
