I have a Toshiba TV with a cablecard. All digital channels were fine up until a few weeks ago. Now just one channel, 806 (ABC HD in Providence) shows a picture but after 30 seconds goes black with the message "weak signal". All other channels including the Boston HD ABC affiliate tune in fine. Any ideas why or how to diagnose? Cold weather broke some wires in a cable somewhere? Thanks.

Sorry to say, we really don't have a lot of experience with CableCARD TVs since we generally deal with TiVos holding the CableCARDs.
But you might, in fact, just have a weak signal that an amplifier can fix. Your cable company should be able to troubleshoot and fix this fairly easily.Been here a long time . . .
