Re: The Hall of Shame - Badcaps Photo Montage
The video on my wife's VAIO PCV-W20 goes black about 30 seconds after it comes on. I think it might have something to do with these.

Re: The Hall of Shame - Badcaps Photo Montage
I'd say it's a sure bet.
It helps more people if you state the make and series of the caps.
[Google can't see what's in the pictures when it searches.]
The date code (if there is one) would be nice too if those are HN or HM.

Re: The Hall of Shame - Badcaps Photo Montage
As above ...recap.... or if you like sent out to be recapped
Dont know with your computer but as a general statement
sometimes the psu can be in the same or similar state too.
and cause similar problems (as well).
(just be aware of that point, thats all)
Regardless that MB "defiantly needs recapping" to start with
Yeah like KC8 said you can post photos here, in fact its more preferred as it keeps the post together.
So on that note
here is Willawakes fine post on how to do it
Inserting Images in your post
you can either leave them sitting at the bottom
(I think it possibly better that way then people can click to look)
or use the "IMG" tags to inline it at size in text
(this way means it load up full so if you upload a big photo file it takes time)

Re: The Hall of Shame - Badcaps Photo Montage
I'm such a complete noob, I have no idea what these mean, really. Here's what's printed on the shrinkwrap: nichicon; 6.3v 3300mF; HM(M); 105.C; H0245Originally posted by kc8adu
This thing is basically a laptop (in a desktop all-in-one format) so I don't think I'm going to be trying to disassemble it enough to recap considering the aforementioned noob-ness.
By popular request, I'm including the pics as attachments to this post. I had to crop them down to meet the size requirements of the forum but they should have all the relevant detail.Attached FilesComment

Re: The Hall of Shame - Badcaps Photo Montage
HM(M) - HM Series (Are Nichicon Brand)
H0245 -> year 2002, week 45
Good chance those are bad.
There was a manufacturing foul up with some of 2002, 2003, 2004 production for Nichicon HM and HN Series'.Mann-Made Global Warming.

Re: The Hall of Shame - Badcaps Photo Montage
Lelon crap on AOpen AK77 Pro (Socket A)
as the board does still POST its worth a recap after cleaning it up..
after the recap its going to be used as an Office/Internet PC with an Athlon Thunderbird 1GHz.
a friend asked me if i have something around 1GHz for his mum (her Pentium 3 died because of a water pipe damage.. they had to leave the house and her PIII was still running when the water got too high
sad...)

Re: The Hall of Shame - Badcaps Photo Montage
I was told these are sachon FZ series. The board is a Mach Speed Viper 939GT4-STD-G. Jetway makes the same model board (Machspeed is owned by Jetway).

Re: The Hall of Shame - Badcaps Photo Montage
Jetway still like to use Sacon nowadays.
I saw some other brands MB OEM from Jetway also come with
many Sacon 6V3 1000μF near different slots.
Besides, I saw many Asrock MBs come with OST 6V3 1000μF in those positions.
I just prefer OST to Sacon though JP caps are my favorites.******************************************Comment

I figure this is the best place as any to make my first post. Plus, include a couple of pictures of why I am here. The attached are shots from my Asus A7N8X v1.04. Yep, I have one of those. It started giving me trouble just a few days ago.

Go ahead ... laugh it up at my expense. It couldn't come at a worse time. I'm getting ready to replace another system and was planning to put all my money into that build. Now it's just a matter of comparing the cost of replacement with a re-cap. I should hear from TopCat soon.
Time could be an issue.
I use the bad board for a sideline business too.

Re: The Hall of Shame - Badcaps Photo Montage
i dont really care.. its just my socket A test boardOriginally posted by kc8adu
i just wondered.. did asus replace the Nichicon HMs with Rubycon MBZ in Rev. 2.0 ?
just found out that my board is a Rev. 2.0 one..
BTW: the print on the board itself (between the PCI slots)
says "A7N8X Rev. 2.0" but the BIOS says "A7N8X-X" !? WTF?

Re: The Hall of Shame - Badcaps Photo Montage
No problem ... I knew what you meant. Of course, I discovered the issue when I was doing a vaccuum and blow out of the board. Now I have a nice clean ... dead board. HA!! I think I may start a thread on the results of my project over in the mobo section.Originally posted by Scenic
That's what I may do. Is that a HAM call? It's gotta be ... I see you are from OH. 73s from ke5clj.Originally posted by kc8aduLast edited by LoTechJoe; 04-20-2008, 03:57 PM.Joe

GLoria GAE 1500uf 6.3v and one of two Nichicon HM(M) 2200uf 6.3v (H0143) from SMC EZ-Switch 1016DT. The Nichicons were on the power board. Replaced with Rubycon ZL (for the Gloria) and MBZ (for the Nichi) since they were the matching values on hand.
One of three Sanyo 1500uf 6.3v WX (S.E.13) from a Socket A motherboard. I can't remember which one. Did not repair it, just pulled the Rubycons and pitched it.Attached FilesComment

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

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? -
Back in 2020 i bought a (2nd hand) compact ATX psu to replace my current one. My PC case only fits very short ATX power supplies so i didn't really have the choice of buying a decent 80Plus unit. The current unit is a modded YoungYear unit that i made a thread about a while ago:
A "nice" YoungYear unit? - Badcaps
The "new" unit is a KDM-M6480 480W psu, the 480W number is a typical KDM bullshit claim of course, but the 24A rating on the 12V rail seemed reasonable and the "Active PFC" claim gave me a bit of hope that this was going to be decent-ish....
