I went to sleep last night and my directivo, RCA DVR39, was working fine. This morning when I turned on the TV I had nothing. I noticed that the tivo was not making any noise at all, no fan, or drive noise, I checked the power connector and it was still in. I unglugged it and plugged it back in and still nothing. No sound at all. Any ideas what to look for? Is there a fuse it could be? Or is it dead? Thanks.
