I’ve Scoured the internet for a teardown video \ guide and haven’t been able to turn anything up. (maybe one of the senior members can?)
anyway, odds are you’ll need to do the tear down your self. id suggest if you do.
take your time, take pictures on your phone every step you take so you can reassemble, take your time. be careful when removing pieces. ( cameras are very fragile and things can break easy) if you find your self getting frustrated, go take a break and come back.
if you don’t feel confident enough you may need to send it out for a repair.
also if you don’t have a soldering iron you’ll likely need one to replace the pin that was broken. also you’ll need to find a replacement pin which also might prove to be difficult.
good luck!
