Sorry for this question. I realized after posting that I had not checked out the cable box. Sure enough, unplugging for a minute and plugging back in fixed the problem.
I've had this unit approx. 9 months and aside from the occasional re-setting itself, it operates fine. This morning only certain channels were viewable. I'm on Comcast, and channels 2-34 and 702-712 were ok, the rest kept saying that the station would be connected soon. We have another TV in the house that is operating fine, so its not the Comcast signal. Any thoughts? Thanks.
