Well.... I'll have to look into that. My new issues are that only the left channel is working through the cab stereo on the aux input from the TV now and I cannot for the life of me get the 20.1 IR remote to control this dang Jensen TV for anything. Looking at this post: DISH learning remote, Jensen TV 2011 View it seems I'm not alone :-(
I'm having the same issue. Our old camper had the A and B connection but the new one does not. The only way to get the satellite to work is a direct connection from the satellite to the receiver thru the door. Don't want that. Any ideas would be great! Thanks!
