LG50 PC1- where is 5v standby derived from?? Can't Post

Ac only connected. line fuse ok. No red led when ac is switched on.
Set is dead with no 5v standby voltage on ac-d pin of connector P800 on YPSU-J012B board. I've tried to trace origin of this back but got lost on the circuit board. Does anybody know where this voltage is derived from? If you haven't worked on this model other models may be similar so I'd welcome any thoughts and advice.
