Shutter button needs a smacking

[philfx]

Hi have the RZ Pro2 with a auto winder. I had a dual cable to it, and I was trying to get the winder to wind automatically ,

and looks like I need to set in M mode or?, but either way, I ended up ruining my shutter release. Now it wont release

unless I tap and push it.

 

Any shop in the Los Angeles area that works on the RZ, or is this something that can be easily fixed if I am able to order

parts from

Mamiya?

 

thanks!
