Neff B1641 oven replacement lamps dont come on?

No there are not any internal fuses for the lamps, its very unusual for there to be any fault on the lighting switchgear, if you have a pcb type control instead of rotary knobs then it could be the faulty lamp short circuited in its brass threaded section and blew the pcb, I have had that once before. Before any drastic measures make sure the bulbs are screwed right home to make good contact. Cheers
