Auto pilot Glare shield display Lights (FCU) won't turn On

[Al Russell 0]

On cold and dark start up my Auto Pilot Display (FCU) lights won't turn on.. When I attempt to turn on Pitch Trim switches on OHP they immediately turn off.

Because the pitch trim switches won't stay on, the FCU displays won't come on...

Any ideas what I may be doing wrong..

Thanks
