Very possible, I'm trying different cables now, as my CM-7000 PAL is doing it again. Last night while I was watching Kimmel all of a sudden signal strength just dropped to zero on all channels. Tried overnight letting it sit, and now doing the disconnect-reconnect antenna lead trick.
The very first time this happened was over the summer. We had a power failure and I stupidly had my Channel Master plugged directly into the wall, I had just moved here and hadn't had a chance yet to get all my stuff situated. When the power came back on, that was the first time it did this, it couldn't find any channels. I've always managed to get the channels back, but it's doing this routine more and more frequently now. So, very, very sad.
Got it at Fry's Dec. 2011, unboxed, discounted at $180, the last one they had in the building. So, it has served it's purpose, no cable for 12 months has saved me $800ish for my $180 investment. May have to spring for a new Channel Master, though, maybe wait a bit for the price to come down as $300 doesn't work for me. I'm not sure broadcast TV is worth $300. I mean it's nice, but not $300 nice!
