Almost every night for the past two weeks since I had Dish installed I've had to unplug Wally to get the signal to lock. I will lose the picture but still have the guide. The TV activity screen flashes 0 out of 0 tuners in use. If I run check status or test installation the progress bar doesn't move and the test screen just hangs but sometimes I may hear the current channel sound in the background. If I do manage to get a picture and use the guide the picture will go black immediately or after a few scrolls through the guide. If I try to turn wally off with the remote I'll get the 'tips' screen on the TV as if it's turned ff but the green light won't go out. In thre end no matter what I try I have to unplug the box and plug it back in. And its not quick to start up. Any ideas??
