Advertisements I can't really describe it better than that, and if it's not a familiar sound for a problematic TiVo, I can record it making it, although I've unplugged it now and would rather not plug it back in again. I first noticed no Freeview signal (which is the source) was being passed through, as the RF aerial loops through to a second TV in the room, thought it might be the Freeview box, as that had crashed again, then saw the TiVo was no longer functioning. It's making a constant rat-a-tat-tat sound, akin to New Order's Blue Monday. The screen is blank and the unit is unresponsive. I know it's happened in the last 24hrs. I've had it a few years, but is it a new PSU that'll fix it, or is it the hard drive or motherboard, and if the latter then I may as well replace the unit? Thanks in advance.
