TiVo Series 3 died -- can I move the hard drive to another Series 3?

    Could be that during the long test it reallocated some sectors that had gone bad, remapping them to new locations that were previously "hidden" and held in reserve for just that purpose. Which means that drive now has less room for error than previously, and is less deserving of trust.

    Couple weeks later, and it's still working; all the recordings (at least those which I've tried viewing) appear to be intact.

    Maybe I spoke too soon ... I had to unplug it to put it on my new TV stand, and now after several reboots it won't make it to the TiVo main menu screen. Either it's stuck with "just a few more minutes", or there's just a black screen which flashes gray once every couple of minutes with the clock stuck at several minutes in the past (i.e. a point in time shortly after it booted up).

    I've disconnected the HDMI, antenna, and network cables, and now the TV is connected to it via composite cable.

    A Tivo with an ailing power supply would act like this. Which one are you using? The one with the bulging capacitors or the replacement? Even if it's the latter, I wouldn't totally rule it out.

    To rule out software issues, I would grab a drive that is known to be good and that can be overwritten, and overwrite it with a 648 image. Then install it and if it boots, do a Clear and Delete Everything. If it boots successfully after that then I would suspect a hardware problem.

    I'm using the replacement power supply I got from Weaknees.

    I notice that after a few minutes after plugging in the power, the lettering for "Almost there. Just a few minutes more" changes from smooth to jagged and it remains like that. Does that symptom mean anything?

    A hardware problem? Booting successfully with a fresh image would seem to indicate that it had a software problem.

    On the latest reboot attempt, nothing happened. Blank screen, no lights on the front panel, and I don't feel the fan blowing.

    With the 652 power supplies, they didn't even bother replacing the defective capacitors so some people who bought their replacement power supplies from them got very little use out of them. I would check if they replaced the capacitors in the 648 power supply you got from them. If they're still held by the white/yellow glue used in mass production then you should try to read the manufacturer names off of them.

    I've seen it before as well as the HDMI output taking on a purple hue. I haven't seen it correlate with anything.

    Yes, software problem.

    Re-imaging alone fixed 8 out of 10 broken Series 3 Tivos that I've repaired.

    The latest reboot reached the Welcome screen again, then the TV screen blacked out with "Ready. Set. Tivo" displayed on the TiVo's front panel.

    How would I know that?

    Tomorrow I'll try to restore it from a truncated backup file I took in 2012.

    I restored the hard drive from an old backup file using WinMFS. But with or without the hard drive, I can't get any response other than the fan spinning ... and spinning slowly. Nothing on the TV screen, nothing on the TiVo's front panel.

    I'm blaming the power supply. I'm sending it back to Weaknees for another one.

    White or yellow-ish goop is used to secure components to the PCB during mass production. If the capacitors were replaced that goop would show signs ranging from subtly sliced to completely removed.

    You can also try to read the manufacturer's names off of the capacitors. Of particular interest are capacitors C402-C702 if you have the power supply made by 3Y and C14-C31 if you have the one made by AcBel. Most likely you have the former.

    Brands such as CapXon, OST, Taicon, and other no-names are bad. Japanese brands such as Panasonic, United Chemi-Con, Rubycon, and Nichicon are good.

    The power board is made by CY. I don't see any goop near the capacitors. The only thing I could read on the capacitors is "CE NHG".

    Clean your glasses, that's a 3Y, not a CY (unless they're counterfeiting the entire power supply now).

    The CE means it can be sold in what was once the European Common Market.

    The NHG is a capacitor series made by Panasonic, so it looks like someone might have done some replacing already, but the NHGs are apparently general purpose capacitors and not the Low ESR types that really should be used, so they may already be failing.

    Strange typo. I know it's 3Y, as it's clearly written on the board, but I must have been thinking about the "C" in CE when I typed CY.

    Anyway, I contacted Weaknees and got the RMA number, so it's going back tomorrow. If their next replacement still doesn't solve the problem, I'm not spending any more on it, and this could mean the end of my TiVo days. Now that I've ditched cable and am relying only on antenna and clear QAM, other less expensive options look a lot more viable.

    Dang, I got my threads crossed and thought we were talking about a model 652160. 648250Bs only have one type of power supply which is made by 3Y.

    Is this a lifetime unit? If not, you probably already spent too much time and money on it already.

    Yes it has lifetime which I got for it back in late 2006 or early 2007. Without that, I wouldn't be trying so desperately to get it ticking again.
