I don't have the Genlock, but I know from some experiments I did myself with external sync, that after loading Kickstart, the Amiga will look if there is any signal on the H and V sync inputs, and if it finds anything, even if not really syncpulses, it will enable external synchronisation. So from this moment on the Amiga needs correct sync pulses from your Genlock to bring up an image. As your Genlock is broken, it will supply a wrong signal, probably only a DC voltge, and your screen stays dark.
