Does anyone have the quantities and dimensions on these for an original S3?
I'll ignore the rest since you were replying to 2 posts and the rest appeared to be directed to Dan.It seems, so far, to be just the caps which have one lead grounded and the other lead connected to either the 12V or 5V output which have developed problems.
As for replacing caps because of what brand they are, CapXon is widely known as CrapXon, but the Series 2 Dual Tuner power supply uses them and I haven't heard of any of that particular model having problems so far, so brand alone is only a possible indicator.
Also, counterfeit versions of reputable brands are being produced.
3Y is the company that made the power supply for TiVo.Who or what is 3Y?
Thanks for the feedback. I've fixed the C402 as that was an obvious cut and paste mistake. I was going by the numbers that I had jotted on an index cards for the rest and I just checked my spreadsheet and found that I had C501, C503 and C504 listed as being together and had not updated C50? there either (I think it had the white "glue" over it on the board).Thanks Scott. I just happened to be doing this same thing right now and figured I'd search and see if anyone already did, though I was already in process so I did it more for sanity check. Here's some updates for you: You listed 401 twice - the one next to it is 402. and 50? is 503. And where you listed 503 is really 504. At least this is how it is on my Rev A2 board.
Those were the 2 that were bulging slightly on 1 of my S3 OLED's and you are correct that they do not have to be leaking to be bad and cause power supply issues.On original inspection I thought all my caps looked okay, but after the 250GB drive didn't work and reading through this thread I took a closer look and the tops of C401 and C402 are slightly domed but not leaking. Guess I'll be replacing some caps
Keith,So I'm fairly sure this is affecting me as well. My Series3 (2006, OLED display) went into a reboot loop this morning - it would take the kickstart codes but not actually start the kickstart routines. I unplugged it for the day. This evening, I just get ticking from the power supply when plugged in, and the fan doesn't power on. (I have the case off, so I'm sure of where the ticking is from). By feel, 3 of my capacitors have a bulged top - C401, C402(? I can't see the label, but it's immediately adjacent to C401), and C701. From the sounds of it, I need to get a Torx T8 (I have a 10, and several larger sizes, but not an 8), and I could probably stand a beefier soldering iron if I wanted to try replacing the caps myself - for that matter, where are people buying caps?
That appears to match what's in my TiVo HD. Note that I've only replaced the capacitors in one of my S3 OLED's but while I was upgrading the hard drive in our TiVo HD, I wrote down the capacitor information for future reference.The cap is number C31. Model ST7002-BW0G by AC Bel.
That would be great since then we'd have all 3 of the S3 power supplies documented.Okay, that's the one made by the same outfit that made the 648 supply.
I've got one sitting out on the bench at the moment, so I'll check some old posts to see if anyone's already compiled a list for that model and if not I'll sit down with the bright light and magnifier and figure out which ones are on the +5V and +12V outputs and post that ('cause those are the ones likeliest to be bad if any are), but it might take a day or three.
I posted a list for the Acbel S3 HD power supply 2 pages back in this thread.Do you happen to remember, and can you provide the link, to where the 652 cap list that's already been posted is?
If not, don't worry about it, I'll find it myself.
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).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?
That looks like it would match what you need based on Digikey's information. The EEU-FR series specifications include Ultra-low ESR.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
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).P10224-nd
