Whirlpool ACM 802/NE Induction Hob fault (Help needed)

[mals]

Hi all. I wonder in anyone can help me I have a Whirlpool ACM 802/NE Induction Hob that completely stopped working the other day. I tried the child lock reset but no joy. No display at all. I disconnected it from the mains supply and removed the rear panel. I have changed the two 25amp fuses and reconnected to the mains and tried to switch it on to see if there was any life.

After a few seconds the display was flashing 1 1 1 1

then n n n n n n
