    TivoToo:

    I don't know enough but do even the supposedly same models have the small official model numbers? In other words, when I was looking online for Images, they had so many and they all suggested looking at the official label on the rear and not counting on my tivo being generically S3 hd.

    I didn't need to look online for an image. I had a backup of the image on the original hard drive that came with the unit. That is what I've used in the past when upgrading the hard drives.

    Latest Status: I have attempted to complete Guided Setup using POTS, assuming that there was some problem in network hardware. However, even when using phone line, I get "Call Interrupted" when attempting to connect to TiVo service. So regardless of whether I used wired or wireless Ethernet, or a phone line, the S3 will not connect to the TiVo servers. I was leaning toward the problem being a hardware issue, but now I'm not so sure.

    .Describe how far you get through the process using POTS and ethernet.

    Edit. I see you added more info to your original post. Need to think about this further. Have you tried a C&DE.

    I did a C&DE first thing before Guided Setup. In desperation, I re-imaged drive again, but did NOT perform a C&DE. I bypassed the Guided Setup and just tested the connection to TiVo Service using Wired Ethernet. It worked. I then forced a connection to TiVo Service. That worked. I then did a system restart with Ethernet still attached. It booted. I repeated Guided Setup, and this time it connected to TiVo Service OK and got the initial channel setup. But, then while scanning antenna for available channels, S3 spontaneously rebooted, and went into a reboot loop. I turned it off and waited about 15 minutes. Turned it back on and it booted into Guide Setup. Random reboots make me think P/S problems, so I pulled out the multimeter again and measured the rails. 5V was good, but 12V was at 10.5, and 3.3V at 2.8. I could have sworn these measured OK when I checked before swapping P/S. I put the HDD into the other S3 and measured voltage on that P/S, and it was even worse with 5V sagging also. Maybe I didn't have HDD installed before and was measuring the rails with no load or maybe I didn't have my glasses on. To my old eyes, the caps look good, but measurements don't lie. Both P/S are bad. They are both same age with same hours, so I guess they had similar deterioration. My soldering skills suck, so I'm pondering my next move.

    If you can't find anyone local to do the repair, you might google "tivo power supply repair" and see if any satisfactory alternatives present themselves.

    Took out the big magnifying glass and examined the capacitors. 3 of them do have a slight bulge. It's the same 3 on both PS. One is C701, the other is C401 and the cap next to it. If I do the work myself, I would need to purchase a soldering iron and solder in addition to the caps, so it might be worthwhile to have someone else do it for a reasonable fee (~$50). The Weaknees option is a trifle steep. For those $, I'd just go buy another Premiere.

    I agree about the weaKness price. There was another option available, at least when I googled it, and it is right at your price point.. I cannot speak to the reliability of this option, only that it exists.

    Depending on the community you are in, the local technical college or high school might do the work for you.

    The local electronics (tv) shop here in my area would replace the caps for that price.

    Probably solder, soldering iron, and caps are less than 20 to 25 dollars.

    I used an image I received and used DvrBars and it restored my new drive.

    I then used MFSAdd in WinMFS then I get an error 9 zonemap.

    What i'm I doing wrong.

    any help is appreciated.

    Ok I put the new restored drive back in the TiVo and tried it.

    It says powering up then it goes almost there then the green screen that says the dvr has serious problems allow it to try to fix it and it might take up to three hours!

    What did I do wrong?

    thanks for all the help everyone

    Don't think you did anything wrong. Not sure about the error. Will have to see if I can replicate. You could let it run through the fix and see what happens. If not I pm'ed you another file. If that one doesn't work then we need to evaluate your set up and process.

    Whenever you use an image from a different TiVo, even though the same model, that image expects to boot up in a TiVo with the same TiVo Service Number as the machine from which the image was taken and the new TiVo expects the hard drive to have the same TSN stored on it as the one stored on the motherboard, so it has to do some stuff (basically set everything back to square one) to resolve the situation.

    Eventually it should get everything squared away and dump you at the beginning of Guided Setup.

    It is working thanks to everyone and special thanks to jmbach for all the help and images.

    I have 2777 sd and 318 HD.

    Thanks to the encouragement of the regular contributors to this forum, I screwed up the courage to try to do it myself. Ordered the tools and parts I would need last weekend, then went out of town on a week of vacation. Packages were here when I got back home Saturday. Replaced 3 caps (C701, C401, C402) on one of the bad P/S yesterday afternoon. When I was done, my solder joints looked as good as original - so I was probably being too hard on myself regarding my skills. Installed repaired P/S back in S3 and it has been running for last 18 hours with no random reboots. For me, the hardest part was removing the old C401 and C402 caps. Trying to hold the board in place while holding the iron and putting a little leverage on the caps to pull them free required some juggling. A prehensile tail would have been helpful. I plan to repair the P/S for the other S3 this afternoon.

    Congratulations!

    You need one of these to help remove the solder. Once the solder is pulled out then the caps are easy to remove.

    $5.80 at Amazon and called a solder sucker. :)

    One of the things at Radio Shack actually worth having is a de-soldering iron.

    Looks like a soldrering iron, but has a big squeeze bub.

    You heat the solder joint with the tip while holding the bulb squeezed (adding a little fresh solder to get some flux in there helps melt the old stuff) and when it liquifies you release the bulb to suck the solder away from the joint.

    Without squeezing the bulb, it can serve as a soldering iron in a pinch.

    Same concept but just combines the soldering iron and solder sucker into one unit.

    I hate to resurrect ancient threads, but this one was very helpful. I accidentally knocked out the power from my S3 that has been running for the past 9 years, and when I plugged it back in, it was stuck in the Powering Up loop.

    I've tested the (expansion) HD using WD's tools and it reported no errors after a full media scan.

    So I suspect the power supply. In testing, I once unplugged & replugged it quickly. The fan didn't spin up, and instead there was a ticking. If I give it a few minutes to discharge, then it ticks once or twice and then comes on. Here are the voltages I've observed:

    Without HD:
    orange = 3.04V
    red = 5.06V
    yellow = 12.81V

    With HD:
    orange = 3.13V
    red = 5.06V
    yellow = 12.34V

    Without HD, ticking power supply:
    orange = 2.9-3.2V
    red = 3.1-3.5V
    yellow = 5-9V
    (all swinging wildly)

    Looking at the capacitors, it seems that C401 and C402 are bulging (though not leaking).

    Do others agree that it's the power supply? I was surprised that the voltages were so close to nominal.

    If I decide to replace the capacitors myself, how should I go about dislodging them from the white glue that's holding them in place? (The glue on C402 has it stuck to the adjacent coil.) (I'd be tempted to go with the Weaknees replacement, but then I have to pay for return shipping and at least one person had his go bad 7 months after replacing it.)
