I have my wall-mounted TV working now (after getting the wall bracket mounted and the TV on it) but the sound does not come through the coach's ceiling speakers.
I have not tried playing a DVD through the DVD player to see if that works yet. I have tried using the remote to the DVD player to find the set up menu (which I think is necessary to program the TV installation) and can't get the set up menu on the DVD player to appear in order to do this.
I'm taking the trailer in for a couple of minor things and will ask about this, but thought I'd try getting the TV to work my self. The AM/FM radio works through the ceiling speakers but the TV does not. I have double checked the audio and video cables from the TV to the wall jacks. Maybe this is my problem.
Any suggestions would be appreciated.
