Yashica GX not firing

[rubenchopapafrita]

Hi guys,

 

Got a GX in today, and apart from some dirt everything was working fine until the shutter button has stopped firing. It was firing correctly at the beginning, but right now it doesn't click and obviously the film lever doesn't work as well.

 

I'm guessing is not the usual sticky shutter blades problem as it was indeed opening before this happened. I noticed that the firing button had some issues, not clicking if the film lever wasn't back to its first position correctly.

 

Anyone with some insight? Couldn't find anything related on the web.

 

Thanks for your help!
