Advertisements Our TiVo had been making progressively more and more noise (like a loud whine), which we thought was the fan, since it had done something similar a couple of years ago and it stopped once we replaced the fan. I ordered replacement fans from Weaknees last night. Then when I got up this morning, it was making a horrendous grinding noise and the green light wouldn't go on. Blank screen also. Is this a hard drive problem? a fan/overheating problem? Both?? Should I try plugging it in again? Any advice would be most appreciated--every time I've stopped in these forums everyone has been super helpful, so thank you in advance!
