Hi All, I am getting "searching for signal" on some of my channels. 359, 331, 244. Prob. some more. I checked ch.480 and it was good, ch481 is "searching for signal". Previous to today everything was working fine for the last 8 months or so. Sounds like my b-band took a dump. Is this common? I know some of them were bad right out of the box, but has it been common for a working one to die? Thanks.
