Yep, just look at my pic at the start

don?
found in a deer made allied 250.lots of dr- numbers inside.

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.

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

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.

just for topcat...
a blown ruby!

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

I've seen a blown ruby on very rare occasions.... 21-gun salute for the dead ruby!!

**trodas** · 06-10-2006, 05:26 AM

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

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.

**kc8adu** · 06-12-2006, 06:35 PM

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!

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.
The stencil (and therefore the caps) could be backwards on the motherboard - it's not unknown!

**trodas** · 06-13-2006, 03:32 AM

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

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.

**willawake** · 06-13-2006, 08:01 AM

if they were connected wrong they would have blown shortly after installation.

like my 5 minute fm!
btw i emailed matsushita industrial and they confirmed my suspicion.one in 50k might get sleeved wrong and sneak past qc

Then we are lucky if it screw itself in 5min...! Imagine that is start poorly dying like Teapos and random lockups and stuff come...!

5 min death is MUCH better

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
