Leica LTM Help with self timer APDOO

[rrunnertexas]

Is there a thread about how to repair the APDOO self timer that someone can share?

I have a IIIf and used the self timer a few times and it worked great. Then for some unknown reason, it stopped working - the plunger does not "plunge" anymore. The timer does work though the cycle, just not tripping the shutter.

Thanks in advance for the help.
