    I tried a two-way splitter and got the same results (things look great with unencrypted QAM and bad with cablecards).

    I'm not sure what to do next. I'm long out of warranty, but I guess I could call TiVo and see if they can offer me a deal to upgrade...

    Thanks for your suggestions!

    You've got a 5 year old machine.

    It's having "strange" symptoms.

    I would be very unsurprised to learn that you needed to replace one or more capacitors in the power supply.

    It could be about time to replace the hard drive as well, but anything wrong with the current one would be much, much more unlikely, as in nearly impossible, to cause your specific strange symptoms, whereas a marginal power supply might be able to manage okay until you add the extra load of the cable card(s).

    If you plan to replace that S3 with another TiVo, then sell it to me cheap, but, if you want to try to save it, search my comments for the word "capacitor" and you'll find a lot, on which I've already spent time writing, about the "capacitor disease" problem and what to do to see if that's your problem and how to fix it.

    Thanks for making that suggestion! I checked out the power supply this morning, and sure enough, there were three bulging capacitors. I considered repairing them myself, but since there are (at least) three that are failing, I thought I might as well replace the whole power supply. I'd like to keep this TiVo running as long as possible.

    I know that weaKnees sells new power supplies for the Series 3. Are there any other places that sell them? (I know I could get them used on eBay or craigslist, but I'd rather get a new one.)

    Caps are cheap... If you can solder.. id recommend you change them and see if that solves the problem before investing in a new power supply.

    Okay, sell me the power supply cheap and I'll fix it.:)

    Apparently DVRUpgrade also sells power supplies, but apparently they and weaknees are really the same people now.

    9th Tee doesn't seem to have any, and I'm not sure if they even mess with anything newer than Series 2s.

    You could look for a (non-lifetime) S3 on eBay that might be cheaper than a new PS. Then swap that PS in. Unfortunately, it would be another old PS and might get, or already have, capacitor disease. The different TiVo models have different PS'es, so be sure you get the same model you have.

    Replacing the caps, even if you have to pay to have it done, is probably a better way to go.

    If you do replace the caps, educate yourself about the need for low-ESR caps so you get the right kind of replacements or make sure that whoever does the repair for you understands what's needed.

    Thank you everyone for your advice and opinions - lots of good points were raised. After weighing all of the options, I decided to buy a new power supply for my Series 3 off of eBay. It was less shipped than one from weaKnees, and I get to keep my old one (I figured I could sell it to someone who might want to repair it and keep it or resell it). I don't have a ton of time these days, so I wanted the ease of swapping the power supply out. Time or money... sometimes you have to pick which one is more important to you...

    unitron, I love the quote in your signature, btw! Classic line from the original trilogy. :)

    You understand it refers to what TiVo did to lifetime S1 subscribers in the UK, right?

    Once you've confirmed that the new power supply fixes your problem, let me know what you want for the old one.

    No, I didn't know that. I'll have to look up what happened.

    I'll contact you after I get the new one installed and test it out.

    The (S1 and not the new Virgin Media TiVo) UK forum is here

    http://www.tivocommunity.com/tivo-vb/forumdisplay.php?f=14

    and the threads about it started early this year, but some of them are still active, so the date of the most recent comments isn't necessarily the best way to find them.

    Yes, you could swap the hard drive and the power supply from a second S3 and see if that resolves the issue.

    The audio/video issues were resolved after I installed the new power supply. Thanks everyone for your input and advice! :up:

    Any chance you have a list of which ones to order (complete set) and where's the best place to get them from?

    You probably don't need a complete set.

    Usually it'll be one or maybe 2 on one of the output voltages.

    What model TiVo do you have and have you had the power supply out and actually found the ones with a slight, or greater, bulge, or leakage?

    Have you gone to Wikipedia and read their page on "capacitor plague" to learn how to spot the problem visually?

    The tops should be absolutely, positively flat.

    Do you have any soldering experience and equipment?

    As to where to get them, where are you geographically?

    I order caps from MCM Electronics.

    The only problem with MCM, at least as of a couple of years ago, is shipping fees start a little high and go up with purchase price, which is okay if you're buying a lot of heavy stuff, but otherwise a bit off-putting.

    But they are good people to deal with otherwise.

    I am having the same problem as AVSman. I found a bulging capacitor in the power supply and had it replaced. Reconnected the TiVo Series 3 and it still is pixelating, freezing, stuttering and then automatically rebooting itself. Any other suggestions? Should I try to replace the entire power supply instead of just the one capacitor I thought was bad?

    Did whoever did the replacing test the power supply in the TiVo?

    Longer than 5 minutes?

    No, he tested the capacitors in the power supply and said they were all ok. Then, the power supply was put back in the TiVo and started up. It didn't appear to solve any of the existing issues. I'm trying to buy a used TiVo so I can replace the entire power supply and hope that works.
