Boiler does not fire up - nothing showing on screen of Vaillant Eco Max Pro?

Boiler does not fire up - nothing showing on screen of Vaillant Eco Max Pro. What is wrong? Seems as though the electrics are not getting through to the screen. Checked fuse to socket - ok - socket appears to work - boiled kettle from it.
