HELP! Yashica 35 gsn

[nickm]

Hello,

I've spent far too much of the past week trying to resurrect an ebayed gsn and i've hit a dead end. when the camera arrived, the electrics were dead. after a new battery and little resoldering from the negative terminal, the battery test light works.

BUT... still no meter. under/over lights don't work, and shutter is always 1/500. i've been told there must be a short somewhere. I attempted to take off the front, but one of the four screws under the skin is completely threaded. Does anyone have any advice on what I can do now? Thanks,

Nick

Sounds like the POD needs replacing..

I have also a bad GSN, which have a new POD, but shows yellow light all the time. So far the file yashica_shutter_trblsht.pdf indicate a faulty shutter.

Remedy = "exchange unit".

To bad, since the rest of the camera is in excellent shape. But I have a GTN that's working, so it's not a priority.

Good luck!

Does it have the critical 2mm thickness?? This is important..

the pad is of proper thickness. i also have one fully functional gsn and am thinking about putting this one up for parts or repair. oh well...

also, as a resource, this is a very good one:

update:

after taking apart the lens, i discovered one of the red wires had broken free from the battery-switch contact in the shutter (this is a gold flexible thing). after putting together an elaborate set up of wires, tape, and tinfoil, i compressed the shutter release part way, and using a toothpick to make contact in the shutter, i got an over/under lamp to go!

any advice on how to resolder this contact, there's not a lot of room around it and removing the battery-contact requires taking apart most of the shutter. for those familiar with the insides of these things, the lower red wire is the one disconnected.
