Any hope for reviving a 7s Meter?

[gdi]

I am considering opening the top of my 7s to see if I can diagnose a meter problem. Any experience on the liklihood it would be fixable?

The needle does move slightly as I tilt the camera, so it isn't stuck. I'm thinking that if I am lucky it will be a connection problem...

All I can offer is that it will definitely help to have a 7s repair manual. The 7s isn't particularly hard to disassemble, but a repair manual does help showing what goes where.
