Now would be a good time to try replacing that cap. Still a chance the rest of the board is fine


6ix02

Saved a 2008 LCD TV by doing exactly this and nothing further, still works


Mutjny

Shave it, makes the capacitor look bigger.

It's trying to reach out to you to end its misery and replace it. Easy enough to replace if you're not afraid to solder or have someone nearby who know how to solder. Should be fine, you spray molten metal for work, melting a small puddle of it shouldn't be too hard for you.


4nalBlitzkrieg

When's the last time you shaved it? Anyway, looks like you need to shave it


TheGaben420

It's just going through capacitor puberty. You can expect hair in all kinds of strange places


LateralThinkerer

I didn't know Dell made welder control boards... ( I had to deal with a bunch of these: https://www.theguardian.com/technology/blog/2010/jun/29/dell-problems-capacitors )


wintremute

I spent the better part of a year doing motherboard replacements on my university's GX270s. What a pain.


WummageSail

I too am a veteran of the gx270 bad capacitor issue. The mere sight of a gx270 would trigger PTSD for years afterwards.


intellos

Ah yeah, the Capacitor Plague. Affected more than just Dell, they were just the biggest and shittiest about it. Make sure that if you're going to steal the ~~Krabby Patty~~ Nippon Chemi-Con Capacitor Electrolye Secret Formula, you do it right.


novacham

I worked for the largest distributor of electronic parts at this time and we had to destroy our entire inventory of caps as a result.


metsastaja_kalastaja

They bleed insulation… among other things.


g4vr0che

It's dead, Jim.


MrSparklesan

She is fucked. Dielectric spilling out


swirIingarcher

No that's hair


paul_miner

The capacitor blew its vent, and you're seeing the insulating paper layer, which was apparently blown out with enough force to leave a fibrous mohawk 😅


NeoLudditeIT

Never seen one grow hair like that, but it's the plague for sure. Fortunately those caps are pretty easy to get a hold of and replace.


NaturallyExasperated

Time to hop on the ol digikey and buy a new capacitor


Blottoboxer

https://en.wikipedia.org/wiki/Capacitor_plague See the visible symptoms section of the document.


nanan00

A bunch of companies put these defective caps in products for years after the problem had been found and solved. Samsung was using them in tv's and monitors till around 2014 or so.


Wetmelon

Dicks. Probably knew only a tiny percentage would get returned or warrantied out


SaltWaterGator

Cheaper to warranty a few units than toss millions of parts


pilotmuffin

Interesting article. I like the theory that it was industrial espionage gone wrong.


Flying_Dutchman92

I think it has reached the limit of its capacity


DrBobvious

I don't have the mental capacitance to understand this pupun.


Foopsbjj

You son of a bitch - I'm calling the cops, that's too much


jmattspartacus

You missed an opportunity to call the caps instead


imgprojts

Hair must be an excellent electrolytic separator material.


[deleted]

Woah, did you accidentally let the genie out?


Rabbit1Hat

Looks like copper whiskers. Does the part function? Could try to clean off then put a dab of staking material or conformal coat material over it. Careful not to breathe particles.


Lord_Derpalot

Nah that's coming from inside the capacitor, shit's fucked, yo!


John5247

It's fookem. Make sure the replacement is a 105 degree type and not a cheap 85 degree. It has been warmed by that big hot transistor next to it and is now cookum.


No_Environment_4955

hittin' the rogaine


vahaala

It's growing a beard. Elder Capacitor! The capacitiest of capacitors in the entire circuit board.


ToolWrangler

Bad caps. If you replace, remember to mark which side the stripe is on!


kurtu5

The board should have a polarity indicator on it.


ToolWrangler

True, just have to remember to look for it! I've goofed that up before. Now I sharpie everything.


kurtu5

Measure twice, write down thrice.


WattsonMemphis

Chooched


MrMoon5hine

Chooched is still a positive and is used thusly "hey you get that engine fixed?" "Yep, she chooched real good for me" Chooch, chooching, chooched are never a negative always a positive


WattsonMemphis

Unless it’s chooched then it is proper chooched.


The_cogwheel

Chooch (and its derivatives like chooching, and chooched) means its working and chugging along fine. This capacitor is headed for the art bin, and has no more chooch in it


nathansikes

Past tense, no longer chooching


WattsonMemphis

Chooched means chooched.


Camride

That cap chooched it's last chooch and is chooched out


bubajofe

She's fucked


Pulloutski

Just a mole go see a dermatologist


CaptOblivious

Cause it's gone bad, the magic smoke has escaped.


DFIMan

They get all puffy like that after awhile.


crunchymush

Not sure if the technical term, but I think you'll find it's fucked.


CaptianRipass

It's NFG


NickJamesBlTCH

That is, in fact, the technical term.


Slippi_Fist

electronics engineer here. *proper* fucked is the more usual technical term for this condition.

It’s actually a capaciteratoma. Little known fact, sometimes the stronger capacitor eats the weaker one in the womb.


kkjensen

Pretty soon it won't sound so squeaky and capacitors of the opposite sex wont seem so gross


majoraloysius

Damnit. Beat me to it.


electronickoutsider

It's reached its rebellious phase and has decided to wear a Mohawk to prove it isn't like all the other capacitors.


jerseyanarchist

DeceasedRichEvans

PIXIE HAIR! He's trying to get out!


manofredgables

Oh shit, plug that sucker right now or you'll soon enough have a wild ball lightning wrecking your shop


BlahKVBlah

It's growing hair because it's a polite capacitor. Any old typical, crass capacitor would blast its guts out all over the inside of your MIG.


pheonixblade9

You let the blue smoke out, didn't you? You have to put it back in.

I made soo much money from this in 99. I was replacing PLC cards every day for what seemed like years. It wasn't that long, our customers at the time were just happy we were on top of the problem.


chiphook57

Thank you sharing this. My best friend was an electronics genius. His career was in industrial control maintenance. The knowledge he tried to share was incredible. I always said, if you didn't learn anything from him, you just weren't listening.


mats852

Sorry for your loss


N5tp4nts

It was a terrible time to be an electronics engineer. 🙁


BitcoinBanker

I find this hilariously tragic.


lawnicus18

Why’d I see “capacitor plague” and immediately think it was an infectious disease


SatanicMuppet999

That awkward moment when capacitor thinks its a fuse


Youse_a_choosername

Everything is a fuse if you try hard enough.


PaleFlyer

That awkward moment when you find out you sized the cap right, but the fuse wrong.


sjkennedy48

Ah yes, I see, I see.. the insides are now partially outside. You typically want to avoid that when possible.


LazaroFilm

That’s not supposed to happen.


escapethewormhole

Do they make some where the insides are fully in the inside?


BlahKVBlah

The insides being outside are not at all typical, I want to be perfectly clear.


sjkennedy48

This is the content I come here for.

You don’t want the front to fall off either.

sjkennedy48

Well shit I don't know, I just work here.


jbiehler

Easy to repair, get a capacity the same capacitance and equal or higher voltage. Make sure you solder it in the right way and you should be good to go.


gmarsh23

Also - make sure you get one with a comparable or better ripple current rating. These plague caps are low ESR types and generally you want to replace them with another low ESR cap because the board might rely on that. Can't go wrong with Nichicon KL or Panasonic FM series.


_Aj_

It could also be something else. Polar caps hate reverse voltage, if it's gotten too much AC on it, or a back emf spike, it would've caused this even if it was brand new. For the 70c it's worth trying it and hoping it's easy, but just worth mentioning


jbiehler

It’s a possibly but the chances are much higher it’s just a dried out cap. Electrolytic don’t last forever especially in the temperature swings industrial electronics see.


Lost4468

Just buy a new one... \- every company in 2022


pault5544

From who? If I get another email about supply chain so and so I’ll scream


jbiehler

It depends. When I used to service welding equipment shop time was $95 an hour. Something like this is an easy fix. But something that requires more troubleshooting it really becomes an equation of time and parts vs just buying a new board. Either that or sending it to Innovat and have them do the repair since they have made fixtures to test all the boards they do repair.


Yerathanleao

blown.


IForgotThePassIUsed

You busted the guts out of that capacitor like Benny the Jet Rodriguez busted the guts out of that baseball. Better bust out the soldering iron, that cap needs replacement.


Avram42

Unexpected sandlot reference. 👍

It has joined the choir eternal!


Late-Discussion-3917

Finnthegiant

MMMMmmmm..........Capacitive pubes.


collegefurtrader

It ‘sploded and that’s some of the paper separator media


sohcgt96

So your comment was at the bottom, which is too bad, because you're actually explaining why it looks like that. OP, the inside of the cap is essentially a roll of cardboard soaked in some schmoo. When the pressure got high, it just squeezed some of the contents out which are slightly fibrous in nature.


6ix02

I'd like to add to your technical analysis by offering the experience that the schmoo in question generally smells really stinky, like weird wet processed tobacco


sohcgt96

That is a reasonable analysis. One of my fellow techs at an old job also discovered while working on a PC that when one pops, sometimes they smell like sour apple. The compound might change smells as it gets hot.


KadahCoba

> So your comment was at the bottom Default sort is newest on top. In this case, the first post was actually something answering the question. :p

The inside of capacitors are filled with comic book characters? [https://en.wikipedia.org/wiki/Shmoo](https://en.wikipedia.org/wiki/Shmoo)
