    Am currenltly looking at this cp110 chassis. Arrived with mains fuse
    blown due to power supply chopper transistor shorted (cause: dry
    joints) .
    Replaced it, plus the mains filter cap which looked to be in a bad
    way. checked resistors of 100R and 120R near chopper - known common
    causes of failure - to be sure. powered set up - OK.

    Now it can come in and out of standby, channels change in the display,
    speaker plops at on-off,I could have sworn I heard the vertical scan
    operating too, but there is no audio or EHT. I checked the 2 wickman
    fuses on the power supply secondary - OK. Also, the set appears to
    have been recapped fairly recently. I changed the 100uF cap on the
    overvolts panel but no joy. Any suggestions here before I dig out the
    schematic? TIA.
