I have a Di622 Nissin Flash, the base is broken. The part that slides into the hot-shoe. Would like a quote on the fix.

Hello, after breaking mine this morning I was able to fix the flash so It can fire from the hotshoe.

Any automatic TTL features will still not work however atleast you will be able too fire in auto, and manual modes.

I simply opened the flash by taking off the hotshoe, and then swiveling the flash head 90 degrees to expose the four screws there. You need only remove the two screws from the front side of the unit.

Open the battery door and gently pull away the front case (Be careful there are several delicate ribbon cables that you do not want to snap. From here you can either unscrew all the ribon cables to free yourself room to solder or try and dodge them.

You should now be able to see the rear side of the PC sync socket. There is a blue wire that joins the outer edge of the socket - this is ground. Solder onto this point and join onto the top left circle of the PCB board of the hotshoe. (Opposite corner from where the ribbon cable attatches) There are copper circles exposed on the pcb for easy soldering.

Next, return to the rear of the PC sync socket and note the orange wire coming from the centre pin. Solder a wire to this point, and then down to the hotshoe PCB and to the circle that joins to the centre pin of the hotshoe. (Trace the circuit paths)

Sorry I did this about 30mins ago and I'm remembering this out of my head.

Goodluck

This part, the 'hot shoe assembly' is much stronger than it looks and holds all the weight of the flash mounted to the camera in those 2 little slots.
Yes, you'll need to replace it.
Are you comfortable with electronics and small components. There are small springs and pins/ball bearings/contacts in there when the cover is removed and wires may have to be soldered in place (I can't remember if there is a plug for those wires inside).
Try here to buy the part you need or contact Sony service (I'm assuming you're in the USA):
