25V 470uF? Any help would be appreciated! This was in an Adam A7X speaker. I replaced with a different uF and voltage closest to the values I thought because it is all I had in stock. It restored the speaker to working condition but it is certainly not what I needed to do as it is putting out less volume than its sister speaker which presumably no issues.
Trouble reading this blown capacitor

I'm sure whatever you replaced it with is fine, you likely have other problems than just this cap, for a cap to blow like this is usually reversed polarity or too high a voltage or it internally shorted.Last edited by R_J; Today, 06:07 PM.Comment

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 -
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 Fuzzy FixHowdy all I have a 90uF Capacitor 200/275 VRMS and measured the ESR . Reading says 00.3 Ohms and about 1/2 a second later 00,0 and says low ESR (Really No Kidding).
I have checked it on the multimeter and reading is 94.7uF well within soec as ir has a 25% tolerance on it.
Can anyone advise me is this capacitor likely to fail in the near future or still good to use.1 Photo-

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
