Well, I guess my luck ran out. It was working fairly good all week (just those minor glitches I mentioned before) and of course on the day of American Idol (starts in about 20 minutes) it goes back to unavailable. I've tried the same thing that fixed it before, messing about with the coax cables at all contact points, but it's just not working this time. I'll try to call yet again and get them to send someone out.... this is extremely frustrating.
