    Yet Another AS15 Gamma Ref chip dies....

    This one The 'G' suffix version in a Technika 32" with a CMO panel.

    Symptom was a very bright well under-contrasted picture with little or no control of brightness with user-control--what colour there was seemed unaffected.

    The chip AS15-G was so hot I burned my finger on it! The gamma test-point voltages were all over the place, most being 0 instead of a 'staircase style' asending values.

    A replacement cured the fault completely.
