I'm trying to help a family member with a problem and wonder if anyone has thoughts on this: He has a Hopper 3 and a 52.0 remote. Last night he had to power down the Hopper in order to move it to a new shelf. Upon powering it back up, it works fine -- except that the remote no longer will control it. He said that while the Hopper was powered down, the remote was occasionally beeping. He's technically savvy and tried everything he knows but is not having any luck. Any ideas for things he can try?
