Loewe Adventos 3981

[Turnip]

Hi Folks,

   Have one of these beasts for repair where Red and Green front Leds glow, Degauss buzzes, no rustle of EHT, then after 10 seconds set reverts to S/by with Red Led glowing.

   With a couple of bulbs in series after degauss posistor is hot, there is no charging pulse from the main cap. Guess P/S isn't starting - any ideas before I seek out a schematic ?   

    Thanks - Chris.
