Hi, im working on a Saunier Duval Enviroplus f28e condensing

Customer Question

Hi, i'm working on a Saunier Duval Enviroplus f28e condensing boiler that is not showing any display at all. I've got power into the boiler and onto both the main board and the control board. The main board has supposedly been fixed by a micro electronics firm that said there was a fault upon it. but still getting no display from the display board. Any ideas which of the three boards may be at fault?
