    AVM-27D5 dead, at turn on, the degaussing relay just keeps clicking.
    All standby voltages are ok, & nothings blown. Unload the 24 volts
    SMPS secondary, then hook it up, & the set works.
    Anyone see this, or have a service manual! Dani.

    weird problems like this can be down to faulty capacitors on the psu
    secondary - try changing them. -B

    If there aren't any open thermistors or varistors in tte primay AC
    power supply Then
    most likely the 24 V secibdary has a leaky filter capacitor or bad
    zener diode regulator, or
    possibly a transistor series regualtor,or optoisolator
