Hey, all of a sudden my HR34 Genie has developed a weird type of problem. Everything is fine while I am watching t.v., but "magically" when I am away from the t.v. for a while (t.v. is left on) I come back and there is a frozen picture on the screen which so far has always been a commercial (don't know if that matters). This has happened to me 4 times in the past couple days It has never happened when I am sitting there watching the t.v., so I have never seen it actually happen live. I look at the frozen picture and then I hit the channel up button and it changes channels and the picture and sound all come back to normal on the new channel. What do you think could be causing this issue?
