I have been googling and searching Tivo Community for a while this morning and have seen conflicting reports. I have a 4 year-old lifetime (or "all in..." whatever!) 4-tuner cable Roamio with a dropped-in 3TB drive. While watching a time-shifted show this morning, the following happened: Symptoms: Boots up to the "Welcome... starting up!" screen. After about five minutes, all four lights on the front of the Tivo start flashing rapidly. Here's what I've done so far: Left unplugged for 15 minutes. Plugged in. Same results. Swapped out the wall wart from a Tivo mini. Same results. Pulled the hard drive and dropped in a blank 640GB drive I had laying around. Same results. At this point, I'm looking for advice. I have seen people with the "flashing lights of death," but I've not seen anyone who got to the "Welcome... starting up" screen. Everyone else seems to have no picture at all. Has anyone gotten to the boot-up screen and had the four flashing front lights? Is this something that can be repaired?
