Neff U1442 oven failure?

The light bulb blew on the main oven and I replaced it with the correct bulb yesterday. Today when cooking the oven tripped out, the bulb had blown and now although the fan runs the cooking light does not come on and no heat in main oven .The top oven works as normal.
Is this likely to be a control panel fault? Are there any fuses internal perhaps?
Any help gratefully received.
Thanks,
Roy
