Question....2009 DRV TK3 Mobile Suite

[crabapple12]

New to the forum but have owned our '09 DRV TK3 Mobile Suite for 14 months. I have about conquered all the learning curves of the DRV except one thing. The TV in the bedroom does not have a signal and I have exhausted myself to the end of time trying to get it to work.........NOT!!!!

Does anyone have the wiring schematics of a 2009 TK3 or know where I can obtain a copy?

Thanks in advance for anyone's time that can help......
