Jensen TV sound

I was just wondering if it's possible to hear the TV sound through the trailer speakers/ I could have sworn that I made that work a few days ago. The TV speakers are weak. I was able to get the DVD to play through the speakers. None of the doc. that came with the unit explains this.................thanks.

Yes you can do this all you need to do is set the DVD (mine is a samsung) to AUX and it should work. Mine was wire wrong from the factory but since you said you had it working I doubt the wiring is wrong. I did not like the suround sound on with the TV as there was a lag between the two. The only option I had was to mute the TV which was OK but then I had the mute symble on the screen. I decided to forget the TV and used the AUX input for satalite radio but it does work. Good luck.

Turn the volume on the TV all the way down and no Mute symbal
