For the past couple weeks I've had an issue with my local channels. I get no picture or sound, only a black, blank screen. No messages or anything. It basically looks like the TV is off. It's only on my local channels and any programs I have scheduled to record are not being recorded. I have to unplug and replug the hopper before recordings are scheduled to start to get locals back and/or to record programs. This solution only lasts a day and it's becoming very irritating. Calls to tech support seem to be of no help whatsoever as all they tell me to do is reboot. Is anyone else experiencing this or can point me in the right direction for a solution please.
