For some reason, when I try to blind scan with my Coolsat, the screen goes blank and then goes to a channel I already have in place. Last night, the blind scan "started" acting funny. When I tried to run a blind scan, the little indicator moved very quickly and no frequencies were listed. When I say quickly I mean about 10 - 15 seconds. Obviously this isn't right. Now, as stated above, it doesn't even do that, it just blanks out. Has this ever happened to anyone before? I'd hate to have to send it back as everything's finally in place. Thanks!
