    But does the cap C5 still show the correct capacitance? Does it show leakage resistance?
    <<<<0>>>>
    The (C100) 68u, 400v cap is 3.6 Ohms on a scale of 20k Ohms

    and the (C5) 0.047u, 630v cap is reading 17.16 Ohms

    THANKS

        BTW 3.6 readings on 20K scale is not = to 3.6 Ohm, 20k scale cannot show 0.0 Ohms resolution, 3.6 on 20K scale = 3600 Ohms.
        Are you reading leakage resistance of C5 off the board? How about CAPACITANCE reading?
        How about the checking of the MOSFET on the heatsink that I told you to check?
        How much experience do you have on testing component, electronics troubleshooting, and meter readings?

          my metre cannot measure capacitance for cap C5

          Bridge rectifier (DS1) - show reading as show in attachment, looks ok to me.
          Let me know your views ?

          Please help me identify DS1 from RS -
          https://uk.rs-online.com/web/c/semic...ons=4294883856


          D9 not available
          MOSFET on the heatsink:
          <G to S> shows 0.81(charged up)
          <D to S> Drops from a negative value to Zero

          Please help me identify this Mosfet from RS-https://uk.rs-online.com/web/c/semiconductors/discrete-semiconductors/mosfets/?searchTerm=mosfet

            this looks like a superior part

            the 3pin part with a Mitsubishi logo looks like a fast diode, not a mosfet

                You also need to find out why R18 is damaged.
