we bought a new edge m17 this past sat and had it out camping that night. we notice that the roof ac leaks thru the vents into the unit. does anyone have any suggestions about how to prevent this. it seems to happen when ppl are moving about the rv. also we could hear the dvd being played but the tv screen is blank with the words "no signal" we tried changing out the cords on the back of the tv to av1, av2 and changed to the corresponding source on the tv. no luck. is there something as simple as a button we are not pushing or has anyone had problems with the cords not being attached correctly into the dvd player itself? it seems like a task to find how to view the back of the stereo/dvd player as it is mounted into the walls.
