Re: Candidate for worst blown capacitor in circuit?
no pics, but i had one that launched the can, shredded the insides, and took the bung/wires off the board. and that's just PCB mounted caps!
chassis mounted caps i've seen obliterate themselves, put a hole the wood cabinet, bend the metal they are mounted on, shatter the tubes around them, mangle the tuning cap and dent the main transformer.Last edited by goontron; 02-20-2015, 01:06 PM.Things I've fixed: anything from semis to crappy Chinese $2 radios, and now an IoT Dildo....

Excuse me while i do something dangerous
You must have a sad, sad boring life if you hate on people harmlessly enjoying life with an animal costume.
Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

Re: Candidate for worst blown capacitor in circuit?
What brand is that capacitor? The K vent suggests it might be Rubycon?--- begin sig file ---

Hello,
I am new to repairing computer electronics, so excuse any mistakes I make.
A friend of mine had a broken graphics card (MSI Radeon RX 5700 XT MECH OC) and gave it to me. It does not power on or show any signs of life.
I identified what looks like the remains of a blown capacitor at the bottom of the board (see picture).
I wanted to replace the capacitor, but I have two questions:- Does this repair have a chance of working? or is a blown capacitor a sign something else is wrong?
- How do I determine the rating/value of this capacitor? or something

Hi everyone,
I'm new to this, so I apologize for not providing enough details. Is there anything else I need to mention? I'm trying to learn more about electronic/board repairs and hopefully fix my own.
The only visible issue on my board is one capacitor, CP813, which appears to be labeled R 221k 2kV (possibly obsolete to B 221k 2kV now). My monitor hadn't shown any prior issues, although it is a few years old. Just before the capacitor popped, there was a high-pitched squeal for 2–3 seconds.
I don't see any other visible damage anywhere else on the board....3 Photos-

by expertreaderHi all, Acer Nitro 5 - GH51M LA-K862P Rev 1A motherboard. I went through all the troubleshooting steps but couldnt find a short on any coils. By chance, ended up finding a blown capacitor PCZ49 which is suppose to be 2.2uF. I can see plenty of 2.2uF in the same +5VALW line which will all parallel up anyway - do you guys think it is critical for this cap to be replaced or i can get away without one?...1 Photo

Capacitor detached from PCB – RTX 2070 Super Founders Edition
Description:
During maintenance on an RTX 2070 SUPER Founders Edition, I found a capacitor lying on my desk after reassembly.
I did not notice it detaching, so I am unsure of its original location on the PCB.
Procedure performed:
- Removed backplate
- Cleaned heatsink and PCB with isopropyl alcohol + soft ESD brush
- Reapplied thermal compound
- Reassembled card
Observed behavior after reassembly:
- GPU powers on and operates normally under...11 Photos -
by GentianI have a 5V 55A led Delta power supply with no output. I found this 7 pin IC 901 damaged as in the photo. All other elements look ok. I checked and every other surrounding componets diodes, resistors and capacitors look ok. I have 2 identical power supplies removed from a led wall which have the same defect with this ic burned but not a working one for reference. I founded by measurements that pin 7 goes to positive hot 450V 220uF electrolytic capacitor primary side. Pin 1, 2, 3, 4 connected together to pcb cooper trace. These four pins goes to negative side of 10uF 50V electrolytic capacitor...
