Hi everyone!! I'm a total newbie to this FTA stuff so bear with me. Just got a new Fortec Lifetime Ultra out of box. Connected to tv (Channel #3) set Receiver switch to #3, plugged in and turned on with back switch. All I see is a picture (I think) scrunched up across the middle of the screen. When I press the menu button on remote the screen fills up but does the horizontal roll thing. I've read the troubleshooting part of the manual and it says nothing about this. Is this a defective receiver or is there something else I need to do to clear this up?
