    While you have the machine apart, hook the hard drive to something that'll boot from the Ultimate Boot CD and run the manufacturer's long diagnostic.

    But if it's a GigaByte brand motherboard, say so first so we can discuss the necessary precautions to avoid having it put a Host Protected Area on the TiVo drive at boot.

    Another cap was bulging, so that was the culprit.

    I went to Fry's and got the closest caps I could find. In several cases I couldn't find 10V so went with the 25V versions instead. Should work OK, they are just a bit bulkier than the originals. I soldered in 10 new caps and it booted up fine.

    With the other one I replaced six months ago I think that covers the 11 that HerronScott mentions in post #26.

    ETA: Didn't see the suggestion about the Ultimate Boot CD until after I was done. If it acts up again I'll give that a try.

    I was feeling bored, plus one of the S3 units I got in for spare parts needed some caps replaced so I took the list of 11 S3 OLED TCD648250B Capacitors from above and made a Project on Mouser.com and shared it to make ordering the parts easier.

    To access the project, click on the url listed below or copy and paste it into your web browser:

    http://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=1a42eea4c1

    Or you can access the project by going to http://www.mouser.com/ and click on the EZ Buy option on the top navigation bar. You can also click on this link or copy and paste it into your browser: http://www.mouser.com/Tools/Tools.aspx. Then enter the following access number listed below into the Project Access ID function.

    You don't live any where near Detroit, do you?

    I'm trying to help this guy

    http://www.tivocommunity.com/tivo-vb/showthread.php?p=9456115#post9456115

    with the version of the S3 HD power supply I've never seen in person (the one similar in appearance and layout to the 648's supply), and I'm worried he's going to get in over his head somewhere along the line.

    Unfortunately no, at least 10 hours of driving to get there. Sorry.

    Feel free to drop in on that other thread and see if there's anything you think it might help him to hear.

    Did you create that project list or Scott ? I would like to get a project list for the S2 power supply The 240 and 540 series have the same power supply.
    Thanks for the outstanding work.

    HerronScott created the list of parts. I had to order them, so while I was on Mouser I saved out the project and shared it.

    HerronScott , thank you again for that list. Just had to swap in my recently refurbished power supply into one of my Lifetime units. Your part list and the fact that it I already did the work meant very little downtime on the unit itself.

    Just to note the symptoms from the unit while it had that failing PS in for others: Reboots, Lost channels, One Cable-Card lost pairing, random stuck on powering up, TiVo software corruption. All of those symptoms started in a matter of a 2 day window. Replaced PSU with the one refurbed using the parts purchased, TiVo software was force re-installed with Kickstart code to fix last of issues, and the S3 has been fine since.

    Actually the 240 and the 540 have similar supplies with the same pinout, but the 540 supply has a little less ampacity than the 240, and probably should not be used in a 240 for extended periods, although it should be okay for a short period for test purposes.

    Glad it helped someone else and I think your project at Mouser was a great idea as well! Waiting for the off-season to pre-emptively repair the power supply in my second S3 OLED which has some bulging caps but is still working.

    The company which delivers the product gets paid. Would you rather pay $10 and get free shipping? Order one item and there isn't a difference. Order two items and paying for shipping would cost less, probably around $15 instead of $20.

    Order from monoprice and some of us keeping adding stuff until the shipping charge bumps up to the next level, then drop that last item.

    Bulging C401 and C402 were the culprit in my S3. Thanks for the list and everyone's input. It made my fix quick and painless.

    Thanks so much guys for the capacitor parts list and Mouser project list! My S3 was stuck in an endless reboot cycle. I checked and found several bulged electrolytic cases. I replaced all the electrolytics on the secondary side and now Tivo is happy again. The Mouser project list saved me a bunch of time running down low ESR parts, thanks so much!

    I'm surprised there isn't a bigger market for this. I had a VIZIO TV power supply go bad due to the Capacitor Plague, and there are dozens of capacitor repair kits for TVs on ebay and Amazon for $10-$15 which include all the required caps, but NONE of these kits for Tivos.

    The guy at lcdalternatives.com expressed some interest, but needed to know what caps to stock for which models.

    It's not like there's any hope of getting hold of a service manual for any of them.

    I ordered 380 capacitors at one point and I believe I managed to get the price down to $7 for the 648250B and maybe $3-4 for the 652/658. I never actually sold capacitor kits, just used them for power supplies people sent me to fix or for broken lifetime S3s I bought really cheap off of eBay.
