Hello, I too had the same problem, however unfortunately none of the above suggestions helped me. I went to the Westinghouse website and found there were no firmware updates for my TV. I called tech support which was option # 3 and explained my problem and the tech replied “try all Sony and Samsung pass codes” and I was able to find one that worked, which was 10178. Oh yeah, I have Comcast and the remote is the 3 series with the red ok/select button…..hopefully this helps someone…good luck!
