My Fetch TV box will turn itself on at random times. This seems to happen if the box is left alone for a few days e.g. if I haven't used it or turned it on for a day or two, it seems to want to turn itself on.
Well, that's a bit odd.
There's ruled out poltergeists? In all seriousness, I've replied to a similar thread in the past, I can't say for sure that it's the same issue.
