Re: The Hall of Shame - Badcaps Photo Montage
Here are some pics of SAM YOUNG capacitors. (Different angles)
You can see 2 of the 1500uf 10v are buldged at the top and the bottom seals are blown out.Attached Filesif you find these attachements useful please consider making a small donation to the site

Re: The Hall of Shame - Badcaps Photo Montage
JetWay N2PAP Ultra board and it's Vcore Evercon caps:
They should be considered as bad caps and added to the list...
The machine has problem starting up (sometimes more that six tries to sucesfull boot-up was need) and also the max. clock was about 2100Mhz for 1.650Vcore and about 2300Mhz semi-stable (but so was the board in general) for 1.575Vcore in Mobile AXP...
Definitively a "neat board" to own. My stepbro want to trash it, but I think I could save it with recapping and let it fold for me

Re: The Hall of Shame - Badcaps Photo Montage
Just thought I'd post a couple of pics of bad caps I've seen - feel free to use them in the first post (photo montage).
Note that the GSC pic was taken after I'd scraped most of the electrolyte off the top of the caps - but you can still see the bulge and residue where it was! The Tayeh pic is a bit blurred on the caps themselves, but it's meant to show the electrolyte oozing out of the bottom.Attached Filesif you find these attachements useful please consider making a small donation to the site

YXB series? How old is that? Looks like a 1997 date code on that Takamisawa relay.PeteS in CA

Re: The Hall of Shame - Badcaps Photo Montage
What the hell... replacement work okay, kc8adu???
I mean - any cap can blow out when you, for example, overvolt it with AC current or when is used on bad designed mainboard that overstress it with excessive riple spikes (my DFI LP B as prime example how to kill Chemi-con KZG ones...) - so, some details will be lovely - probably in separate thread

Re: The Hall of Shame - Badcaps Photo Montage
A blown Ruby is not unusual for me. We have Optiplex GX270 systems & I've seen probably 7 or 8 Rubycon caps that have either been bulging or leaking. It's always in the same place, right between the RAM sockets and the AGP slot.Comment

Re: The Hall of Shame - Badcaps Photo Montage
that is in a ge-fanuc plc psu.
think easy bake oven.the nichicons were toast too.i service a similar unit in a mitek cyber saw that was only 2 years old when its caps spilled their guts.the saw operators have been known to keep a pizza warm in the plc rack till lunchtime!Comment

Re: The Hall of Shame - Badcaps Photo Montage
Are you sure the caps are in the right way round? Rubycon should almost NEVER fail; when they do it usually means they are connected up wrong or the board is providing severe ripple current.Originally posted by scarfman
The stencil (and therefore the caps) could be backwards on the motherboard - it's not unknown!You know there's something wrong when you open your PC and it has vented Rubycons...Comment

Re: The Hall of Shame - Badcaps Photo Montage
In such bad designs I would suggest bridge the caps with 100nF SMD ceramic caps - it won't fix the design flaw, but it does help the lifetime - at least partly

Re: The Hall of Shame - Badcaps Photo Montage
If they are, then Dell's vendor would have installed them that way. My theory was that there's two small chips next to this cap (I'm assuming are voltage regulators) that are extremely hot to the touch, enough that they discolor the board over time; I think they are baking those Rubycons.Originally posted by Tom41Comment

Re: The Hall of Shame - Badcaps Photo Montage
if they were connected wrong they would have blown shortly after installation.Comment

Re: The Hall of Shame - Badcaps Photo Montage
I've heard people say that capacitor failure of socket7 motherboards was rare due to the low power consumption of the processors from that era, well I'd just like to share some badcaps from 2 particular SS7 boards I've owned
First picture are 3 GSC caps from a Gigabyte GA-5AA (ALi V chipset)
Second picture, is a failed (leaking) Tayeh form an Epox EP-MVP3C2 (VIA MVP3 chipset)
Sorry for the resolution, the pictures are old and were taken with a webcam

who lives in same town-
I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.
For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).
https://www.badcaps.net/filedata/fetch?id=3591771
https://www.badcaps.net/filedata/fetch?id=3591772
It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

Introducing... the POS-124Z which really is a POS:
Yep it's a POS allright.
I tried powering it up. It's a KILLER - not fried, but sure will fry things! I got 21V out of it unloaded according to my DMM!
I tried 21W load (car lamp) - got 16V, which is really pushing that lamp.
Then I tried a 50W load (car headlight) - got 13.2V. Not too bad but this is with the heavy load...except the circuit breaker kept tripping.
So I had to take a peek:
EIEW. Looks like a Darlington emitter follower + Zener device. Heatsinking?... -
While our PSU hall of shame thread is fun I thought It'd be fun to have a ripple hall of shame thread too
I'll go first out, it's an industrial PSU that offers +15v -15v -5v +5v rails.
However it has been mounted on a frame with DC/DC converters for producing +12v and -12v as well.
The caps for this have gone a bit high ESR
The measured ripple is around 1700mV, or 1.7v!
After recapping the ripple is gone, also note that the scale on the scope is 50mV/div instead of 500mV per div in this shot
-And that's how you know you have a qualifying... -
Hi any suggestion would really help.
I have Hp Envy X360 13 which is AMD.
Model : 13-ar0005AU
motherboard No : 18740-1.
Problem : can't turn on.
After inspecting the motherboard, I discovered that one of the hall sensors was broken. Can't find the schematic for this board, so not sure about this SMD device number.
Does anyone know the serial number of this LID Switch? -
I have here a Magnum IA.100 which belongs to my parents.
The unit powers on & when the relay kicks in, you get a pop from the speakers (this might sound weird but is usual behavior for this amp). However, you get nothing coming through it from any of the inputs & no pops and crackls from any of the controls.
Because of the sound from the speaker when the amp turns on I have assumed that the output section probably works but I could be wrong & I'm not sure how to test that side of things further.
