Cookmaster101 DF broken clock and fan oven?

Electrical power to the convection oven and grill but no clock readout. I know the fan oven needs the clock set to the correct time to function, so consider it is the broken clock that's dragging down the fan oven too! Read Steve's post about the internal fuse, but on inspection found there is no fuse fitted in line from the power supply on this model.........help
