SOURCE: QFlash does not fire
You have a defective PC Cable.
Turn on flash and wait until ready.
With PC cable connected to flash only.
Short out center pin to outside of PC Cable, this should fire the flash.

there's a part in inside that triggers the light .. it might need to be fixed.
Please contact Nikon Tech Support to walk you through resetting the flash.
a. Have you tried that? it's in the Manual

If you know basic soldering, Open the old hot shoe from base
(4 screws).Note down the position of the wires.
Try to fire the flash with shorting two trigger wires,most ly it will fire.
If the springy contact is adjustable do it.If it is not repairable, you can get metal hot shoe from ebay easily.
Caution: metal hot shoe will short circuit 4 TTL contacts (on digital camera) ,so you need to put cello tape at bottom of hot shoe with only center hole.
Hope this solves.
