Not exactly a repair tutorial but rather more of a tune up for the shutter.
As many have experienced the XA series shutter button can become unresponsive.
I retired my xa2 last year as a result of shutter button issues.
Recently I picked up a couple of XA2 cameras for a few bucks and wanted to dig into the issue.
It was easy to fix. I'm sorry I did not take better images for a tutorial.
I was not expecting to post a thread but now that things worked out well… I thought I would share my experience and the iPhone documentation images.
1 Open the self timer lever and Remove the bottom plate (5 screws).
2 Carefully remove the clamshell cover watching not to loose the stop bearing.
3 Remove the rewind knob and top plate. Carefully pull the top plate off.
4 Remove the three screws holding the shutter button assembly together and in place.
5 Clean all contacts with white vinegar and gently pull the 4 contacts of the shutter button outward to re-spring some new tension.
6 Re-assmble. Test the door repeatedly before putting the bottom plate back on. It took me a few tries to get the bearing in the right place.
In the end I found it easiest to put the bearing into one of the stop slots in the clamshell cover and reassemble the camera upside down. Once the door slides smoothly all is good to go.
Here you can see the bottom cover is off as is the top clamshell. The little "barrel" shaped bearing is clear to see. The screw parallel to the bearing does not need to be removed.
Here the top of the camera is removed. Next is to disassemble the shutter button unit (brown board).
Here is the assembly opened up. Clean all the contacts on the underside of the brown board.
Here is the bottom of the red shutter "button". Clean and ready to re-assembly. I gently pulled the tips of those 4 tabs to put a bit more spring in them. Now with new tension the shutter is responsive and feather light as it was when new.
