So I got this QL19 with a faulty light meter. All the mechanical parts works fine and I popped the upper cap open and gave it a brief clean. Afterwards I figured I'd pop in a new battery just in case its not too dead. Then suddenly the light meter comes back to life! I set the camera to different ISO and exposure time settings and it all seemed fine. Then I pulled the trigger and the meter popped right back to the side and stopped working. I gave it a hard shake and it somehow started working once more, and then stopped working again.
It feels like something's loosen with the grounding but I couldn't find the wield point of that. Anyone had similar problem before? Any ideas? Thanks.
