    17ips20-r9 23253538

    Hi,

    Please can someone confirm the two components part numbers on this board, since the Vestal schematic doesn't seem to match the components actually used.

    The OHM for Resistor R129 (connected to FAN7529 CS pin) and U300 IC?

    Thanks

    What is the value of R129 that IS used on your board? the schematic lists 100Ω. U300 lists FAN6300

      They often don't match what's on the board.

      SG6742HR is U300 in some revisions of that board.

        For U300, check which pin is ground. if pin #1 is ground, it is likely a SG6742HR, If pin #4 is ground it could be a FAN6300

          Can we see good clear straight shots of the whole top and bottom side of the board?

            The problem being is the pictures I have (before R123 blew) are not clear enough (typical as I can read quite a few others) and as we know Vestal schematics rarely match real life

            Thanks

              Hi, the ground pin is as per the schematics (pin 4)
              Thanks
