speed channel 234/70 has been blank for the past hour here in clinton twp, mi.
I'm in Columbus. I've had this problem with many HD and sometimes with the corresponding SD channels. This has occured for a year or more, but seems to be getting worse.I guess it's a signal strength problem. I have not had a service call yet to check this.Yesterday, while watching the History Channel HD and the Golf Channel HD, the picture froze and then went black. The History channel and a 4-5 other channels remained black for 6+ hours.Besides the picture totaly going black, I've had increasing macroblocking and momentary picture freezing the past year. This is on multiple channels.It's time to call for a truck roll!
If you're still experiencing issues with channels, please contact customer service to troubleshoot or set up an appointment for a technician to come out.
They came back on about half hour after i posted this.
