Advertisements Turned on the TV and the Premiere (w/CableCard) was having "problem tuning this channel" on every channel. I pulled the power cord and put it back in. "Welcome! Starting up...." Then "Just a few minutes more...." Then back to "Welcome! Starting up..." Cycle repeated three more times before booting up normally and all channels were operating fine again. Might this just be a fluke, or do I need to prepare for a future repair job? Thanks!
