It appears that one of my S3 TiVos has died. I have owned TiVos since the early days of the S1, but this is the first hardware failure I have experienced, so I do not have much firsthand experience diagnosing and fixing such problems. The failure occurred upon rebooting after having to momentarily disconnect power from my HT cabinet. My Premiere XL rebooted fine, but my S3 hung on the Welcome Powering Up screen with all LEDs lit. Prior to that it was working fine. I was aware of the capacitor failures TiVo owners have been experiencing, so I opened the enclosure to inspect the power supply capacitors. C701 has a healthy bulge on top, and the top of C502 has a slight bulge. All of the others look ok. With the top of the enclosure removed, I powered up the S3 so I could measure the power supply voltages. I noticed that after a 5-second delay the LEDs came on, and then I could hear the hard drive spin up followed by 6 loud clicks and then it spun down. The clicks were coming from the hard drive, but did not sound like noise you normally hear from head seeks. The noise I heard sounded more like the heads being parked or unparked, and was very tin-like. It sounded more like the heads were hitting the metal enclosure of the hard drive. The following sequence would be repeated each time I powered up the S3: 5-second pause, all LEDs lit, drive spins up, 6 clicks, drive spins down 10-second pause, drive spins up, 2 clicks, drive spins down 10-second pause, drive spins up, 2 clicks, drive spins down 10-second pause, drive spins up, 6 clicks, drive spins down 10-second pause, drive spins up, 6 clicks, drive spins down 10-second pause, drive spins up, 2 clicks, drive spins down 10-second pause, drive spins up, 2 clicks, drive spins down Front panel LEDs remain lit, nothing else happens after this. At this point I am pretty certain I have a drive failure, but I measured the voltages to check the status of the power supply: Red 4.60 V (stable) Gray 8.69 V (stable) Yellow 5.06 V 5.42 V (unstable) Orange 3.12 V 3.16 V (unstable) This does not look good to me. I believe yellow should be 12 volts, red should be 5 volts but is probably within tolerance, orange should be 3.33 (perhaps also within tolerance), and I do not know what gray should be. At the very least the 12 V supply is bad and could account for why the hard drive was not working. Just to be sure, I removed the hard drive and installed it in a PC and attempted to run WD diagnostics. Neither the BIOS nor WD diagnostics recognize the presence of the hard drive. So at this stage I believe I have both a power supply problem and hard drive failure. I have a lifetime subscription on this device, so I plan to repair it by replacing the power supply capacitors and the hard drive, and will use this opportunity to upgrade the drive to 1TB. Here is my question. I do not have a TiVo S3 backup image, however I do have another working S3 with a month-to-month subscription. My plan is to make a backup image of the working S3 using WinMFS and use that to reimage a blank 1TB drive. I assume the lifetime subscription is tied to the serial number on the motherboard and not the hard drive image. Will this work?
