    OK then. I found the parts list elsewhere in the forum. Now I need to locate my gloves and scalpel. Thanks.

    So my new caps arrived in the mail and they are definitely not the ones I thought I needed. Too tall and skinny. Anyway, I am replacing a Capxon 1000uf 10v 105c C729 vent. Can anyone point me to the right replacement cap on digikey?

    If I recall correctly, you had the power supply that we didn't have a list for yet and unitron was going to create one (ie the second model used in the S3 HD TiVo's).

    Yeah, I guess so, but I don't want to put ALL the responsibility on the poor guy...I figured out I had the dimensions wrong by doing some research on badcaps forum. Also, I picked up a multimeter and I can start compiling a list of which caps correspond to which voltages on the mobo...Can anyone point me to a good tutorial on how to get started with this?

    Are you sure that's 10V and not 16V? Also, what are the dimensions of the capacitor and the lead spacing?

    Yeah it is 10v. I was confused after reading the cap lists for the other power supplies for the S3 that didn't have any 100uf 10v caps, only 16v. Lead width is 5mm. Diameter is around 8. Height is 15.5, probably 16.5 seated. I picked up two of these from digikey: P15317CT-ND

    I haven't been able to clear any bench space to do any power supply dissecting yet, but if you get the right uF (exactly the same), the right Volts rating (the same or maybe the next step higher), get one rated for 105 degrees, and one that's low ESR, then the physical size/proportions do not have to be an exact match as long as it fits where it needs to go.

    Even with the exact same ratings, one brand will be a little taller and skinnier, another a little shorter and fatter.

    That looks like it would match what you need based on Digikey's information. The EEU-FR series specifications include Ultra-low ESR.

    So what did you order the first time?

    That's an EEU-FC series which is low impedence/ESR but not at as low as the FM/FR series. It probably would have worked although the lead spacing is 3.5mm instead of 5mm so it would sit higher in addition to the 20mm taller height to begin with (would depend on whether there's anything limiting the height like a heatsink).

    Got two more caps today. Still no luck. It looks like the 5v rail is dead because the exhaust fan doesn't spin. I have power to the HDD and the ethernet leds on the back turn on. Still getting the flashing green light on the front panel. Any ideas on which caps to replace next?

    Yeah, replace the TiVo. Why would anyone waste this much time on a $50 box?

    Here's the latest - got my hands on a working PS and it looks like the problem is not the power supply after all...Clearly its a Mobo issue which I believe is a death sentence, but let me know otherwise.

    Also, I have two power supplies for the TCD652160 if anyone wants to PM me. Located near CT/NY border but will ship if necessary.

    Premiere 4 here I come!

    I had some weird issues with my Tivo HD 652160 that programs would just stop and reboot without warning. I replaced the hard drive and it would go through the power up screen, get to the end, reboot and then go to a GSOD. I switched back to the original 160GB hard drive and it did the same thing. That indicated to me that the capacitors were the most likely problem. I read all the pages of this thread and made a list of the caps I needed from Digi-Key and what they would replace.

    Tivo HD Digi-Key PN Manufacturer PN
    C501 10V 2200uf RLS 0720 P15323CT-ND EEU-FR1A222LB
    C502 10V 2200uf RLS 0720 P15323CT-ND EEU-FR1A222LB
    C504 10V 2200uf RLS 0720 P15323CT-ND EEU-FR1A222LB

    CapXon 200V 470uf 1189-1197-ND 200TXW470MEFC18X40

    C402 10V 2200uf RLS 0732 P15323CT-ND EEU-FR1A222LB
    C407 10V 2200uf RLS 0732 P15323CT-ND EEU-FR1A222LB

    After replacing the capacitors I was able to get the unit working again. I also used a clean image on the hard drive followed by a Clear and Delete Everything to have a fresh start. The Tivo seems to be working fine. I did have to re-pair the cablecard (another suspected item) and re-establish all the season passes.
    During all of the issues with the Tivo HD, the wife convinced me to get a Premiere. I called Tivo and was able to get a Premiere with Lifetime Service for a little over $400 as a Verizon customer since they are changing their FIOS service (stomp, stomp, stomp...take note of that if you wanted to try that deal)

    Hopefully, this info helps someone with a Tivo HD. There is a lot of info on the OLED S3, but not much on the HD 652160.

    Wobly,

    Great info but can you edit your post and include the power supply vendor/part number and the TiVo part number as apparently there were 2 different power supplies used in the S3 HD. I posted the S3 HD part numbers from the one I have (page 4) but it sounds like you might have the earlier version.

    It seems I have the same power supply that has gone bad. I have a Series 3 HD. We had a power blip one morning, that afternoon we wanted to watch TV and no signal from Tivo. The Tivo had a blinking green light on the front. I unplugged it and tried to restart it but all I get is a blinking green light. The fan comes on but runs slow, the ethernet lights come on in the rear. I can feel the drive running but it seems slow to me. I called Tivo tech support and they say blinking green light indicates a power supply gone bad.

    I took it apart and all of the capacitors on the pwr supply look good to me. The pwr supply is 3Y part no 3BS0158312GP Rev 1, also has CP-1319R2 printed. The Tivo part no. on the board is SPWR-00011-000 Rev B0 .

    Should I just replace all the capacitors? Are there some common ones blown that I should only worry about? Has anyone fixed one of these boards? Unitron do you have a compiled parts list for this board?

    I have the same board and my symptoms were the flashing green light and the rear exhaust fan wouldn't turn at all. My ethernet lights turn on and my HDD turns on and seems to run fine (decent whine out of it indicating good spin).

    I replaced two bulging caps (both of the 1000uf 10v caps) but had no success so far. I also ordered a "working" power supply off of eBay but that gave me the EXACT same results I had before with the problems I described in the paragraph above. I am thinking it is not a power supply issue for me and would be interested to hear of other diagnoses. Hard drive? Mobo? What would make the exhaust fan not spin if the power supply is in good shape?

    I have a Premiere 4 arriving today but I'd like to get this one working again as it is lifetime. Does Tivo take them back for repair? Or is anyone interested in taking a look?

    Thanks for the response. Tivo offered to do an exchange for me for $79 and keep my existing service intact so I'm going to go that route.

    I had similar issues for a Series 3 (OLED) and it wound up not being the power supply at all. Rather, it was the hard drive. If bad, it can't hurt to replace some caps though. For you, I would pull the hard drive out and run some full extended tests on it (don't tell TiVo you did this). If the test come back OK, then its something else. If they fail, then time to look for a replacement hard drive.

    My unit's hard drive test came back with errors so I knew something was at least up with the hard drive. I then used WinMFS & replaced it with a fully working drive (Western Digital 500GB model) and all has worked great since.

    Did your exhaust fan not turn on either?
