When I first moved in, cable on, my Mintek DTV working, now same setup , the tv is not receiving cable TV. I used another tv, hooked up the same cable line and it works...so for some reason I can't enjoy my Mintek anymore except to watch DVD. I don't have the manual and have gone thru channel setup on channel 3, gone thru dvd mode, tv mode, and tried numerous times, and now am very frustrated. Pls contact me...this is 3rd email request.
