Can't speak for a Hopper3, but my regular Hopper started going black, then screen freezing. Spoke with Tech they recommended, immediate replacementThis started early this morning. I have a Hopper 3. While watching TV, either live or a recorded show, after a few minutes, the screen goes black. Changing channels brings the screen back. Obviously, I tried rebooting and unplugging it several times, to no avail. The software is 309, so, nothing new there. I need help ASAP!
