Someone hooked up my NexxTech DVD player directly to my TV. He had it working when he left and now I cannot get a dvd to play. The dvd player is turned on but the TV is on channel 3 for fios. I tried switching to an up channel on the TV to get to channel 4 thinking that might work as a dvd station, but it jumps directly to channel 7. Do you have any suggestions? I'm sure it's wired correctly since he had it working when he left, Seems like I need to switch to some aux channel for the dvd.
