    Title correction: 'How to identify shorted capacitors, you desolder them and test if shorted.'
    I think you are missing the point to inject voltages.

    Some times the ceramic capacitor gives short to ground on the board and there's no problem in the board can you tell us about that case.
    Thanks

      Yes, some power rails are connected to a pch, cpu and graphics chip, those chips have low resistance to ground…

      They do go open. They can develop high "equivalent series resistance" ESR. They can develop leakage ranging from in specification to out of spec but undetectable malfunction all of the way to shorted. They can suffer a reduction in capacity usually accompanied by increase in ESR. Look into ideal component characteristics versus real components which all have resistance, capacitance and inductance. Good luck!

    How would we identify the value of a capacitor that's shorted so we can replace it with a new one ??? Any help would be greatly appreciated guys ☺️

      You kinda screwed. I don't think you can figure that out.
      You'll need a schematic or donor board.

      sometimes you can find example circuits of ic's in which you can tell the different capacitors used

    • @Swenser
      @Swenser ปีที่แล้ว +1

      Sometimes rows of caps are of same value so you can measure the one next to it with cap meter. You can guess by measuring other caps on board and seeing most common values. It's all just educated guesses though.

    • @nd0mble

      using capacitance meter or smd tester or if you dont have replace with the same size

  • @kuangalenga154
    @kuangalenga154 3 ปีที่แล้ว +3

    So you are saying that if the multimetre beeps when check for continuity then that means the capacitor is short, is that right?

    • @jbvtechnologies
      @jbvtechnologies  3 ปีที่แล้ว +3

      That depends, when checking it outside the board then big yes, yes …but when connected to the board you should be careful and check the power rail where the cap is connected

    "You can see that It's tracked" "You can see a big "track". What does "tracked" mean? Then you say, "bent, bent, bent" Where is it bent? I see solder blobs on the ends.
