    BeoCenter 9300 CDM12.4 laser current adjustment

    I am repairing a 9300, with the CDM12.4 laser.

    The Service Manual main part has adjustment procedures for the original CDM4 laser, but in the SM Supplement for the CDM12, there are circuit diagrams only, with no instructions for adjustment.

    Does anyone know which trimpots must be adjusted for what current, and at which points on the PCB is this adjustment made?

    This is a picture of the PCB after capacitor replacement.
