I have Asrock H61M-VG3, which, for some reason, doesn't have VIDSCLK(800mV instead of 1.05v), which should go to PWM controller, also pin on pwm controoler which is getting VIDSCLK, seems corroded(Voltage measured from resistor which then goes to PWM controller)
Any ideas why this could happen?

Re: Project: COMMANDO
upd: tried contact cleaners, sadly, it only cleans, but isn't removing corrosion from solder(some solder became BLACK from corrosion), so, I think that only resoldering components will helpLeave a comment:

Re: Project: COMMANDO
Jeez, I've forgot that I have contact cleaner spray! Thanks!
About caps, some of them have the white stuff from inside on the outside, and i don't think how it supposed to be...
Sadly in my country I don't have a reliable source of any caps, exepct for JB and epcos, but no polys(Belarus btw lmao). I'll try to find some good ones.
Also, the caps which have their contact ripped, it happend only for 2 caps, and idk how, looks like these are stuck in solder for some reason... Other caps went out easily...Leave a comment:

Re: Post help identifying capacitors here
I think you're correct !
There are also AV5K caps as I can see on images from google

Re: Post help identifying capacitors here
Can you give full name of the videocard ?
I recal EAX brand from mid 2000's, it was something about audio stuff, i think games used it.
Maybe some custom audio caps for the EAX ?
upd: looks like Chinsan(Elite), but they have little bit diffrent markings...Last edited by xnRS; 12-01-2022, 12:20 AM.Leave a comment:

Re: Post help identifying capacitors here
It might be a Rubycon, look closer, and if you see a K vent, then it's Ruby
The print format looks pretty close...Leave a comment:

Re: Project: COMMANDO
Water from the sink won't make board even more corroded cuz' of salt in it ?
I'll give it a try then, thx
I hope SMD components will survive this one...

Re: Project: COMMANDO
So, first clean up after 2 years
Removed radiator for easier access, plastic on pins was so hard, that they flew out from radiator
I've brushed the board, but didn't make the picture of clean board.
Then, I've started to remove bad caps from the most damaged part of the board, 3 of them left their leads, as they are for some reason stuck in solder
As you can see - board is heavily corroded, and there is even some rust on parts
And now to the most disgusting...Leave a comment:

Project: COMMANDO
Little backstory:
It all started 2 years ago, when I bought this motherboard in very... very sad condition.
Seller said that it was installed in a PC, which was stored in a Balcony, which was very humid, and motherboard became... well rusty.
So, even in this condition it was, in fact, working. But it didn't had ethernet, either PCI-E or PCI wasn't working(I forgot what isn't working, as I tested it 2 years ago) and I think it was all the problems it had. I've tried to do something with it back then, but it was pointless, as I didn't had any soldering... -
Re: Post help identifying capacitors here
Big capacitors brands are sometimes making caps for vendors, for example - Panasonic FL and FJ, NCC W for seasonic, NCC PSF Black polys and Nichicon/Fujitsu FPCAP FP10K and FP12K...Leave a comment:

Re: Fake polymers?
Also Rubycon did the same

Re: Fake polymers?
SEPC caps with C3 index, 4SEPC560MX+C3 for example
Also I barely could find C3 caps on mouser, only this 2 caps

Re: Fake polymers?
ohhhh, ok then
Then it makes another question - why panasonic, for example, makes some SEPC caps with short leads ?...Leave a comment:

Re: Fake polymers?
whoops, looked at datasheet - there in fact were AX 3300 25, my bad, also found them on LCSC [url]https://www.lcsc.com/product-detail/_SUN-Elec-Industries-25ME3300AX_C242046.html[/url]
So, I guess not counterfeit, again, my bad
BUT, look at little caps with X vents, for example sellers which are selling WG series caps with X ventsRe: Fake polymers?<br /> <br /> <b...046.html[/url]...Last edited by xnRS; 11-27-2022, 08:36 AM.Leave a comment:

Re: Fake polymers?
As I think, it's AX series rip off, but AX never had 3300uf 25v caps, also there are 1800uf 6.3v ripoffs of WG series, i have them at home lol, they came with ChongX(Copy of ChengX and Chang caps xD) 1000uf 6.3v caps...Leave a comment:

Re: Fake polymers?
But why it should be avoided? Just interested. As I understand short leads are caps made for factory, and it's much easier then trying to guess Length of leads to cut...Leave a comment:
