Polaroid HD flat screen TV with DirecTV

Question

I pressed some wrong button on control trying to use DVD. Now nothing works except the power. I have pressed reset button and unplugged TV for 15 minutes. I am trying to get it to go on vidio 6 to watch TV, Instructions say TV must be on "setup" channel to work., and to use Mode button to go to "setup" I find a setup button at top of the polaroid remote. Is that the one to use? On the Direct TV remote is a button that moves right or left. On the left is a directv logo. I leave it set on that. Is that the "mode" button?
