    Re: Need help identifying Ceramic Capacitor

    So can you force the lights to come on? What is that trip pot for?
    What DC V do get on the two lytics caps on the right side of the board (right side of the red cap)?

      The component looks a bit like a tantalum cap but it has the letters VAR1 next to it. The component is also next to the main power wires. This indicates it's a varistor. Searching for
      varistor vf05

      shows that it's supposed to be high resistance when not powered.

        Thank you Elektrolite, Very Interesting. It has no resistance when not powered. Just double checked it with another meter. Is there an equivalent one on fleabay? Maybe one that resists a little more current so it wont happen again?

          Is it possible to test small ceramic disc capacitor with analogue meter?
          by chth96
          I read EBOOK of Testing Electronic Component and found that

          "In order to test the small blue resin coated ceramic disk capacitor which has 104 50v specification,it is possible to test this small ceramic capacitor by making use of analogue meter.
          Set to times 10Kohm that has 12v output from the probe to check disorder of ceramic capacitor.
          It is not uncommon that testing result of digital capacitance meter is okay,But It show shorted reading when you check it with analogue meter."

          Is it really possible to test small ceramic disc capacitor with analogue...

          RTX 3080 FE Identifying capacitor
          by Prolog
          Hi people, I hope this is the correct spot to post this, I'm new to the forum.

          I have an RTX 3080 Founders Edition which has a burnt up capacitor (it was in parallel with another capacitor which appears damaged too), so I am hoping to be able to identify the capacitor values and order replacements.

          I hope these photos make it clear which component I am referring to:
          (yes, the soldering is a bit botched from removing the blown one, I know)

          I have found the board schematic (attached), but there does not seem to be a boardview available. I have never...

          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....
