I keep my PC without the side panel on my desk, two feet from my face...The capacitors do seem to be swelling and bulging on my Epox 8RDA+, and they might blow any time soon. If a capacitor decides to blow, is there a chance it could splash hot acidic electrolytic fluid onto my face and scar me for life? Gosh, I feel like an Indian woman...

Ummm... First I'd recap it (or have it recapped), and then put the side back on. If the caps are bulged, they've already dried out, so you won't have to worry about electolyte. It won't really harm you anyway if you wash it off in a reasonable amount of time... If your skin in sensative, I guess it could cause a rash or irritate your skin. Your eyes would be the main concern having your face near it... (I'm trying to type this without laughing, but I'm sure a few have wondered about this)... If you question the functionality of a device, I certainly wouldn't have it close to your face. While the likelyhood of a cap exploding or projecting anything is extremely unlikely, it could happen... If you install an electrolytic with the polarity backwards, it will vent (unless it's a bipolar)....
Here's a way to eliminate any fear of this: POWER DOWN THE SYSTEM BEFORE REMOVING THE COVER!!!! A cap without power will not vent or explode, PERIOD! If you're experimenting or working with an electronic device, always use safety goggles!<--- Badcaps.net Founder

Actually, most of the caps have already leaked the electrolytic fluid from the top...the motherboard is still running fine...although I should really get those caps replaced. I have a (slightly inferior) backup motherboard so I'm not in dire threat of having my computing eliminated or anything.
I'm actually trying to save up to buy brand new top of the line components to replace ALL my hardware, sans the mouse and my l337 fUNC mousepad. Ya know...I'm a little paranoid, I don't really want the hardware from my current rig kinda like..."spreading their diseases (if any)" onto the newer hardware, so I plan to upgrade all at once. Even this god-forsaken 10 year old Viewsonic monitor. And this Microsoft keyboard. I read somewhere that "90% of computer problems exist between the monitor and the chair," so the Microsoft keyboard is to blame. Damn Microsoft.
Also, I learned from the doctor today that I have acid reflux disease, which is very linked to my nerves. I read on this site that when capacitors blow, they might sound like firecrackers. I celebrate the 4th of July every year with highly illegal and explosive fireworks, so I can tell you that firecrackers are loud, and that my rockets are responsible for some of Florida's "accidental" wildfires...
Now, if one of those things blow, it could startle me enough to make me vomit and spew the acidic contents from the ghetto of my stomach onto my precious PC components, thus melting them down into the primordial goo in which they rose from. I don't believe they are functional that way.
Oh well, I guess an extreme person like me that likes side-panels removed from PC's has to endure a certain danger level...it's part of the job. By the way, I'm afraid of bees and wasps.Comment

Hi, I have some 32 bits computer motherboards that need repair, as they fail to
power on.
Here are some examples :
(N.B. "capacitors" indicated here are electrolytic capacitors located in the onboard
switching supply area).
(N.B. #2 : I could not find a 3300 microF aluminum-polymer with a higher voltage
than 6.3 V.)
1 - Motherboard #1 : this is an Asrock K7VT2 (socket A) that still works well. To put it on test
I replaced capacitors with aluminum-polymer.
3300 microF/6.3 V. x 4 replaced by 3300 microF/6.3 V. (KYOCERA... -
hey all, iv got my favourite battery charger here which iv had for many years probably 15 years now or maybe even more. it still works good but thought id open it up to clean the dust out of it, lots of dust inside but now its clean and noticed 4 capacitors inside it and wondered if i should replace them.
it has inside:
2 x 47uf 16v caps 105c branded as Su'scon (lol sounds sus to me)
2 x 470uf 16v LZ105c branded as G.Luxon
not heard of these brands are they any good?
iv attached photos of the charger and the board inside for an idea on the type of... -
I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow
This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board
After all of... -
I have a 2007-era Panasonic VHS combo that is full of of Elna RJG capacitors. I am trying to test the capacitors to diagnose the machine and then select replacement capacitors but I can not find any datasheets for them. I did find a Elna catalogue from 2007-2008 but there is no mention of this capacitor series. Where these specially made for Panasonic and so not made available to the public? Any ideas what to find out what the ESR values should be without the datasheets? They are all between 10V and 50V and 47uF and 1800uF. None are leaking or bulged but I know that they need to be tested to be... -
I picked up a 70" Samsung UN70TU7000WXZA. The original owner said they were watching it when the power surged and knocked it out. I pulled the back off the TV and disconnected the main board from the power board, and the LED backlight came on, which I was told meant the power board was good. When everything is plugged in the standby light will not come on, looking at the main board BN94-17775A with a thermal imaging gun I can see one of the chips labeled 3202 is 251 degrees F just sitting idle. I found a replacement board, BN94-16115X; this board has the same symptoms, except it is a different...
