    Trouble reading this blown capacitor

    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.

      Thank you for confirmation. Unfortunately this will mean a specialty order but one that is necessary! Thanks again!

        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.

          well the voltage ends in 5, for safety i would call it 35v
          specially in audio.

            Look at the last picture 25V, but 35V would be fine as well

              Capacitor detached from PCB – RTX 2070 Super Founders Edition

              Title:
              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...

              Blown capacitor repair on MSI Radeon RX 5700 XT MECH OC
              by MeetingIncapable
              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
              ...

              Samsung C32HG70 - Blown Ceramic Capacitor (CP813)
              by NuclearSpartan
              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....

              0.00 ESR reading on a capacitor
              by Fuzzy Fix
              Howdy 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.

              Found a blown capacitor - is it necessary to replace?
              by expertreader
              Hi 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?...
