I'm a bit new to AVSForum, but have been an avid reader for a year or so.
I got a new tv, (Toshiba Regza 46XV648U) and our HD DVR gave me problems like crazy. It wouldn't change channels using the remote, (the one that came with the DVR from charter, or my Harmony 880). I moved the DVR off the tv stand, and put it face down on the floor, and it works just fine. I had an old Samsung tube hdtv in the living room, and that worked just fine. I do rent, so I don't want to be re-cabling the whole house. I do however know the people who lived there before I do, and he said he had the same problem with his Pioneer plasma. In googling the problems, and calling charter, I received 2 new remotes, and they replaced the DVR once.
I found online that somebody had the same problem, and they bought a monster power conditioner, and it seemed to fix their problem. Does anybody here have an idea as to if that would actually fix the problem, or if there could be something else to do?
