Needle not moving on Toyota 4001 machine?

I inherited a Toyota 4001 machine. The main problem is that the needle doesn't move up & down.
I haven't used any sewing machine in 25 years but it would be very handy for several things I need to do now so would welcome advice.
It also blew the lightbulb and tripped the fuse in the house and now the motor isn't whirring any more (though I think this might just be a case of needing a new fuse in the power plug or foot controller).
