PANASONIC TV (ALPHA CHASSIS, model TXC81URE) no EHT, etc

Currently looking at this TV which has only the channel indicator at power-on. nothing else comes on - no EHT, audio etc. no whines or other noise from inside.

-Line transistor checked Ok,

-D854 checked Ok

-I changed the 47uF 50v cap in the psu which looked stressed,

-checked R567 fusible in B+ line, measured good.

- using a dummy load 60watt bulb in place of the line transistor gives nothing at all, no voltage at collector.

I'm sure this is something simple I have overlooked, and will keep looking...meanwhile any ideas gratefully received. Ben
