Advertisements Totally confused! My cable went out last night (local outage as verified via phone). When I checked today no channels would come in so I called the cable company (I rebooted before and after calling them). They were of no help. So then I tested the signal strength. To my surprise it is high AND the channel shows up! Go to the guide and that channel that I tested shows up, but the rest do not. So then I test a few more channels and THEY show up then only AFTER testing the signal strength. So now I have to test EACH channel to get it to show back up. What the heck is this ???
