I looked through all the threads, but did not see my issue listed.
My HR24-500 seems to turn itself on for no apparent reason. It will also record a program here or there without being programmed and change channels. It seems a hard reset fixes it for a while, but it occurred again yesterday.
Am running current national release firmware.
My first 24-500 did the same things. I blamed the recording of shows that I hadn't wanted to record on my own clumsiness, but I've seen other posts that stated that the same thing happened. The first thing I noticed was the 500 turning itself on randomly, then I noticed it had recorded content that I had no interest in. I posted about all this a while ago. Let me do a quick search and see if I can find the posts...OK, I found the thread. It's short, but the OP details what I saw, just search for this string: 24-500 went completely berserk again!
All those things and more happened to my 500. I swapped it for another 500 and that's been running all right. Put it in the same place, so I know that my system had no adverse effect on the original 500.
Just hope that your experiences don't turn into a mirror of mine. That 500 did things that I've never seen before and certainly don't want to see again.
