    Edirol FA-101 blown Elna capacitor

    The Edirol FA-101 is a multi-channel firewire audio interface. It features 2 microphone inputs, 8 balanced inputs and outputs, optical digital input and output and MIDI among other things.

    It had a blown Elna 10V 1000uF RJF series cap in the power supply sections. See attached picture.

    The capacitor was causing awful squeel sounds in audio streams along with repetitive clicks. To be fair, this unit has been powered almost continuously for the past 3 years and has never given any other issues. Replacing the cap with a 16V 1000uF Samxon capacitor fixed the problem.

      What series was the Samxon replacement capacitor? Hopefully not a GF series, which is unreliable.
      My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

          I actually replaced it with a KM series (which is general purpose - not low ESR) just to make sure there was nothing else stuffed in the unit. I have some 1000uF 16V Rubycon MCZ caps on order now to replace the Samxon.

          Thanks for alerting me to the GF series though, I was unaware it was bad.

          Cheers!

              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....

              How can I test non-polarized capacitor?
              by chth96
              I desoldered samwha NF capacitor(50v 5.6uf) from PCB circuit of 29inch CRT TV which have symptoms of no display after I heard sound of inrush of current to TV whenever I switch on this television.
              I measured ESR value of this non-polarized capacitor(samwha NF capacitor 50v 5.6uf) by means of MESR-100 ESR meter and It displayed 0.3 ohm

              And When I measured its capacitance with digital multimeter and LCR-T4 Mega328 meter, It displayed 10uf from DMM and 8uf from LCR-T4 meter.
              I found catalogue of samwha capacitor(samwha-catalogue_3.pdf file), which is attached to this thread,...

              Is it no harm to replace with capacitor without ripple current rating?
              by chth96
              When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.


              Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
              But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.
              Rubycon YK DataSheet (b...

              Should I replace polymer capacitor?
              by chth96
              a few days ago I finally purchased mser-100 v2 and I tested its abillity of measuring ESR value.
              I found that It shows pretty accurate ESR value for electrolytic capacitor,But When I measure polymer capacitor of dreamcast game console,I found that one third of polymer capacitor's ESR value is more than twice the value of ESR meter table.(for example, I measured one polymer capacitor of 6.3v 100uf, It showed ESR value of 7.68)
              Although my dreamcast now turns 20 years old but it still works. I occasionally have played game with it.
              Is this ESR value of polymer capacitor correct?...
