    I've got the S3 HD power supply not shown on the weaknees site.

    AcBel

    Model ST7002 - BW0G

    I had to replace C17 and C27, which are both 2200uF, 16V., and are on the +5V line, just upstream of C20 and L3.

    (Don't forget you have to use Low ESR, 105 degree rated caps)

    AcBel is the other supply I have.

    As far as I can tell, the two different S3 HD power supplies that I have are interchangeable. I can understand manufacture changes over time, but what's the point of weaKnees carrying two different ones when the the two are (most likely) interchangeable? It's also interesting that they offer exchange credit for one but not the other..(?)

    Thanks for all your help! :)

    They are interchangeable as far as both deliver the same power to the TiVo with the same pinouts on the connectors and both have mounting holes that line up with the mounting point standoffs in the chassis.

    Your eyes can tell a difference, your TiVo will never know.

    If Weaknees only offers core charge back on the other model, in other words if they don't mess with the Ac Bel at all, there's a niche market for someone to move into.

    Major bummer... I've changed out the capacitors on both power supplies; tested the WD160 that came with the S3 and the WD2TB and both tested "no errors" with DLGDiag 5.19 short test. The S3's are still not booting up. Both are stuck the initial powering up screen, and I don't hear any drive chatter. Is it possible the original image somehow got corrupted? It's been sitting unused for years. Any thoughts?

    Anything's possible.

    Even though you say the hard drives test OK, I would try a fresh image on a different hard drive (known to work, of course) for testing purposes.

    Agreed, just don't overwrite that original 160GB drive.

    And did you disable Intellipark on the 2TB with wdidle3?

    I'm curious. Why are you suggesting not to overwriting the original drive with a (different) fresh image?

    Yes.

    Because there shouldn't be anything wrong with it, and it's already set for that TiVo's TSN, and it's not impossible for an image to be bad.

    Have you tried any of the kickstart codes yet?

    Why not run the DLG diagnostic long test? It will take a while, of course, but it will read every sector on the drive. I'm not sure exactly what the short test reads.

    I'm curious... if that original disk is good but the image is somehow corrupt, what good is the fact that it's got the TSN for that unit? Why not just put a new image on that drive?

    I've never actually used kickstart for anything (yet). Which one's would you recommend?

    Good idea, it's running now.

    But you don't know if the image on the original drive is corrupt or if the problem is something else.

    About 60 seconds after power is applied to a TiVo you should see some sort of change in the front panel lights.

    That's your cue to hold down the pause button for about a second and then release it and enter the 2 digit kickstart code.

    Take the original drive, put it in the TiVo out of which it originally came, disconnect everything from the back of the TiVo (no cable, no antenna, no network) except the power cord and a composite video (yellow RCA plug) cord connected to something with a composite video input. (You can hook up the red and white audio as well if you wish).

    Plug the TiVo power cord into the wall.

    Wait about 60 seconds until the lights change, then hit pause and then enter 54, which should access the S.M.A.R.T. tests built into the drive's firmware.

    If you've already run the WD long test there's no need to actually run any tests on the drive while it's in the TiVo, so find a way in the menu to exit without running any tests.

    What we want to see is if things can get as far as the motherboard accessing the drive's firmware.

    You've got 2 TiVos with apparently the same problem and apparently we've eliminated power supply problems as the reason, so it's going to take some careful and painstaking detective work.

    Do you have any other hard drives available for experimental purposes?
