My Panasonic Dimension 4 combi oven nnct867m has no power?

My Panasonic Dimension 4, nnct867m, combi oven suddenly lost all power. I pressed the Stop/cancel button after using the oven and it lost all power.
I have checked the external fuse and tried a different socket, still no power.
I have also had the internal fuses checked ie; F1 16A clear fuse and F2 10A ceramic fuse, both are working fine.
I checked the live input (internally), this has power but there is no power to the control panel or to the front display.
IS THERE ANYTHING ELSE, I, AS A 'LAY PERSON' COULD CHECK? Or do i now send it for recycling and buy a new one? Any help/advice would be greatfully appreciated.
