I put a 22 inch TV there in the space provided facing the dinette where the antenna and power connections are. I used a swivel and swing out bracket attached to the floor of the shelf just above the TV rather than drill into the wall. The TV sort of hangs from the floor of the cabinet above the TV. Easy peasy.
I also installed a 26" LCD TV with DVD player in the bedroom. I hung that from the wall. On my unit there's a small cover panel at the base of the bedroom wall that backs up to the tub. By removing that cover, I could see the position of the wall studs and then I could position the bracket such that the main screws went into a stud. Very secure and solid. That bracket also swivels and tilts, etc so you can get a good viewing angle.
