The Hall of Shame - Badcaps Photo Montage

Re: The Hall of Shame - Badcaps Photo Montage

Mentioned bad caps on irc to someone, and he got this photo...

More "TMS" caps, this time out of a HP system. he can't find any other brand on them either.

Willawake, want to add TMS to the photo montage?

aw that is just gross. they have expensive rubycon MBZ there as well.

do we have permission to use the pic? it is a great pic. what happened to the 2 removed fets? toast?

They probably died when the capacitors gave up the ghost. Either he took them off because they're DEAD, or they got so hot, they melted themselves off the board.

Re: The Hall of Shame - Badcaps Photo Montage

It looks like they were never there - just a manufacturing option.

Re: The Hall of Shame - Badcaps Photo Montage

I have the same motherboard that you guys have reported to have bad TMS caps! It is just not used currently and is in an anti-static bag right now. My looking on that motherboard I have, there are United Chemi-Con and Sam-Young caps where the TMS caps would go. In the back strangely there are three good G-Luxon general purpose caps on the motherboard I have in a bag. In the front of the board there are three Rubycon MBZ caps and the two good brands of caps I can see on my board in a bag is the Rubycon and United Chemi-Con caps. The Sam-Young caps on the the bad cap list but they haven't failed yet.

I don't think it had FETs there; not only do the pads look like nothing was soldered there, but he said the board still works great, he just put in the spare pile when he noticed the caps. (knowing it might not work great for much longer. heh.)

I'll ask him about photo permission next time I see him.

tms=too much shit?
btw the "missing" parts are for an optional phase not used on this model.

BTW, you can use my photo of the YEC in the Photo Montage if you like.

Re: The Hall of Shame - Badcaps Photo Montage

TMS caps are very bad. Instead of the usual yellow/orange stuff we see come out of other caps we see TMS caps leak out chunks of dark brown stuff. Yuck.

Re: The Hall of Shame - Badcaps Photo Montage

Anyone have a capacitance meter? Some brands (i.e. Teapo) tend to fail with no physical signs... best way to document them would be a photo of the capacitor's rating next to a photo of the meter reading far lower than it should...

--Randy

Every bad cap I've had, except for shorted ones, tested fine for capacitance, including the Fuhjyyus from my Antec and the 1uF I replaced a few days ago for my TV (lower half of picture really stretched out). OTOH their ESRs were all high, again except for the shorted ones.

Re: The Hall of Shame - Badcaps Photo Montage

Many of my "torture" victims can be double or triple the rated Z, but the capacitance is still in-spec (though much reduced from the initial C - +/-20% is a really loose standard).

Re: The Hall of Shame - Badcaps Photo Montage

Heres a failed Fulltec (bulged), Jee (bulged), and a CS (bulged with junk coming out the top) capacitor from a group that I pulled from an older rebadged Leadman LP-8800D that I was recapping "for fun". Ironically, the only cap that was still good (or at least looked good) in the O/P section was a 1000uF Fujiyyu, so you know if the Fujiyyu surived these must be bad.

Re: The Hall of Shame - Badcaps Photo Montage

Here are some GL caps from an older Biostar slot A motherboard:







These four were clustered around two MOSFET heatsinks that get very hot. Out of the 12 total caps on the board, these were the only 4 failed. Board was still working fine, but for longevitys sake, I replaced those 4.

Re: The Hall of Shame - Badcaps Photo Montage

Time for my submission. Two bad Chemi-con KZG 1500uF 16V caps from DFI LP B mobo (tought the rest looking quite OK, so maybe the one is just faulty and drag down the other one with it?) - pics can moderator took from my thread about it there: https://www.badcaps.net/forum/showth...?t=1345&page=2 (likely the 4th one or so - your pick - or the second one? )




Now my Epox 8RDA+ caps - one example cap, two pictures:


Cap type 2200uF 10V GCS (re) 105°CT31A

Friend old dead (burned mosfets because caps lost their capacity) ECS K7S5A mobo:

Cap type 2200uF 6.3V G-LUXON LZ 105°C 1117 (M)

Enjoy!

Re: The Hall of Shame - Badcaps Photo Montage

In the first three pictures, why are the failed caps in PCI slots?

The ECS K7S5A motherboard has been known here to catastrophically fail when the caps go bad in the MOSFET area, killing the MOSFETs.

[trodas]

Re: The Hall of Shame - Badcaps Photo Montage

Well, because I obviously desoldered them from the mobo
You want me to solder them back in order to take a photo?

Re: The Hall of Shame - Badcaps Photo Montage

While UCC KZG series caps are not suitable for trodas's system, they are not bad caps in the common usage of Badcaps Forums, as I understand it anyway.

[trodas]

Re: The Hall of Shame - Badcaps Photo Montage

I do believe that one of the cap (the burned-looking one) was faulty and dragged down the other too by excessive overheaing and losing capacity - therefore stressing the other one over the limits to the breaking point...

At least that is what I think happend.

Still, they did go and ain't quietly, after all

until we see more reports of fails they are considered ok. Guys, please continue the discussion on trodas' thread.
