I have a CISCO RNG150N box and I subscribe to HDTV. For the past few weeks the HD channels blink off sometimes every minute like they are doing today. When it blinks off, the screen goes black and there is no sound. I can watch the same show on the non-HD channel without experiencing blinking. The TV is only a few months old.
I called tech support and after all sorts of troubleshooting, I was told to bring the box in for an exchange. I did that and the problem still exists. Please advise what should be my next step. Thanks.
