One more potential cure for your CM-7000 PAL when it suddenly, randomly blanks and gets a zero signal strength on all channels. My channels went dead, and so I picked the unit up, and gently rotated it slowly, flatly, in the air, keeping it level, in a slow circular motion. While I was doing that, the Channel Master magically was able to suddenly receive a signal on the channel I was tuned to. I very, very carefully placed it back down and it has been working for a few days without incident.
I have also elevated it to provide ventilation. It sits elevated on two piles of DVDs, about six inches off the floor, with empty space under the center of the unit for air circulation. I also have a fan blowing on it constantly. Mysteriously Channel Master did not build a cooling fan into this unit. It's a surprisingly boneheaded decision in that the unit is otherwise, as best as I can tell, perfect. It is the best thing I've ever bought except for the incredibly frustrating antenna loss situation, which I am wondering is perhaps caused by overheating maybe? A previous poster speculated that there is perhaps some kind of defect in the way the antenna input is seated inside the unit, so maybe it's a combination of defects that cause the sudden signal loss. Whatever it is, I'm willing to do whatever it takes to work around it because the unit is otherwise flawless, extremely user-friendly, and a joy to use and have. When it's working, it is brilliant, and even after the TVGOS goes away, I'll still be able to program it manually using some kind of online guide and still get to watch my shows and not have to pay anyone anything.
