    Code Q62 is showing on my sm74-4 with cpc1.04, the middle cpc won’t work now, and the light above the cpc also isn’t working. Anyone have any idea what is wrong?

    Hi sir:

    Normally this happen with Q62 in Cpc 1.-04:

    Malfunctiony writing of an internal characteristic
    curve. Repeat procedure

    2) If the light does not Lit, check for a) loose or broken wires b) bulb o lamp or Led faulty c) measure if there are Voltage at terminals , see your schematic diagrams.
