Without knowing what exactly doesn't work anymore, it's a bit difficult to point you in the right direction.

There really isn't that much technology behind it, but quite a few O-Rings. My guess would be one of these being stuck/broken or something similar.

Attached is the Schematics for the A.P.A., maybe that helps already.

I am not sure how it comes apart....perhaps one needs to carefully pry the button covers off. From the schematic/parts list posted above, it looks like the o-rings are standard sizes. A quick internet search for parts indicates that Scubagaskets.com has some replacement parts for the APA:

It would be good to know what the issue was with you APA inflator and whether you managed to get that issue resolved.

I don't want to hijack this thread, albeit it appears to have been dormant for a while, but I wanted to draw attention to this thread Tusa APA Failures - Potentially Dangerous? where some issues with the Tusa APA are also being discussed.
