Yeah, I thought about that, and checked that. But that would only explain problems controlling the satellite receiver. This thing stopped controlling all IR componants it was set up for. Also, I can tell it is not broadcasting any IR because my panasonic plasma would have a little light that would flicker whenever it detected IR remote signals, whether it was for the panny or not. It's as if the IR just stopped working, but then the UHF stopped working too. It's very strange. My wife was using it when it happened. She used it, and a minute later, tried to change the channel and nothing. The thing is probably dead. I left the batteries out of it overnight and tried again this morning, no change. Guess it's destine for the trash can.
