    2 fuji ga645zi: lcd problem and shutter not firing

    I have two fuji GA645zi that have started to show problems.
    My third camera is still ok but showing problems as well(light not working).
    I would like to fix them or have them fixed by someone (I am in Europe)

    camera 1
    The problem is the flex cable at the hinge that is getting cut.
    I have lost almost all digits and the camera is not working as it should. The ribbon is cut and the camera can't understand if the door is opened or closed because the contacts switch at the back of the door are cut.
    I can't find a cable with the right pitch 0.9mm to bypass the ribbon. I have some experience in repairing but as far as I am aware FUJI does not sell spare parts.

    camera 2
    The shutter is not firing. The camera focuses the first time the battery are inserted and fires but the leaf shutter does not open.
    What could it be?How could I fix it?

    Can these be fixed for a reasonable amount of money?
    Any ideas or advises on how to fix them?
    I have a third one that is working ok but don't know for how long.
    Any help, suggestion is appreciated.

    p.s For someone out there openin a camera is not a game!!Always discharge the capacitor that can be fatal or don't attempt to open, it's not a game!!

    What about jumping the broken section?
    Using ~30 gauge wire or if you can find a flexible circuit with the correct number of lands. Maybe from a P&S.
    Jumping these things can be a bit tedious but is certainly possible.
    Using an X-Acto knife or razor blade scrape the plastic away and solder or try using conductive glue.
    I said it was tedious didn't I? Especially the scraping part.
    Heavily sedated for your protection.

    2 fuji ga645zi: lcd problem and shutter not firing

    I have one of these and a GA645. Frank Marshman, who works on these (he fixed an LCD issue on my GA645), says the big weakness in the GA645zi is that ribbon cable and the poor design of it being worn over time by simply opening and closing the camera back door. He says there's no replacement parts and once that goes the camera is shot.

    Indeed the edge where the ribbon cable goes is quite sharp and this is an issue I've been reading here for a while.
    Thanks anyone for advises, I just remembered I sent a mail to Frank Marshman in the past about this issue and indeed there are no replacements.
    I'll try to bridge the gap somehow but the pitch there is too tiny to solder for my skills.
    I'll ask him about the stuck shutter camera but sending to usa and getting it back would probably cost me too much.

    I've seen there are companies in Usa creating PCB circuits from CAD pinouts (the same ribbons used in cellphones) but have no idea how much that would cost.

    It's a pity to leave home such a good camera (we just met LOL) for hiking that has the power to slow me down from a digital shoot shoot shoot overdose
    (omd-em5+ manual glass is rather amazing in these regard though)

    @giaphoto Any success with this camera mate? i am an electronic technician by trade and have tools and equipment to fix these sort of problems.
    I have just bought a faulty GA645Zi, i did no research first and thought i could deal with the problem of no LCD but i think i am sharing the same problem of the camera thinking the back door is open as it does not auto wind on the next frame, though if i turn the wheel it advances the next frame. (it was sold advertising that the you have to manually wind on the next frame.)

    I am wondering if you have opened the camera up at all to inspect and taken any photos? the batteries are now dead in this camera and i am reluctant to open her up tonight as i want to do more testing first.

    I think we can beat this camera, there are far to many people just tossing them away. And i will be travelling the world for the next 6 months and really want this camera to be my everyday worker.

    I watch with keen interest. My zi simply has a fading rear LCD, so much so that I dare not use any other ISO film than 100, because I just won't know whether I've set it or not...

    My LCD went finally went completely about 2 years ago. I had bought a well used ZI in 2003 and the LCD starting having problems after just a year or two. If you turn the dial counterclockwise a few turns you end up at max ISO of 1600, then each click clockwise is 1250, 1000, 800, 640, 500, 400, 320, 250, 200, 160, 125, 100, 80, 64, 50, 40, 32, 25, auto. Also EV comp is reset when the camera is turned off so that can be set by single clicks when powered up. A little inconvenient, but it's given an extended life to the camera. It has served me well. Last year I picked up a 690II, no LCD, no batteries and big beautiful negatives, though it takes up a lot more room in a backpack.

    They are certainly wonderful cameras and great fun while they last, but the cost of convenience is a lot of potential failure points. Some can be recovered from, others cannot.

    Little update,

    I disassembled the camera enough to be able to inspect the ribbon cable.

    Unfortunately the way fuji had decided to route this ribbon forces a couple sharp bends on a not so flexible cable. Causing a lot of stress on this very important cable, especially when the film door completely open.

    I would recommend anyone with a working GA645Zi to try and avoid allowing the door to open all the way. Maybe try to load film resting the camera between your legs allowing the door to only open 90 degrees (or something like this). This will surely postpone cracking the ribbon and extending the life of your camera.

    Below is a photo of the damage done to my ribbon, it is completely split in two.


    I will be doing some research for techniques in repairing/ joining this sort of ribbon but i don't believe it is going to work as extra length on this ribbon is key.
    To make the camera usable I am planning on identifying which contacts on the ribbon are connected to the door switch, and do what i can to connect the door switch back into the computer. So at least the camera will not think that the door is always open and can auto advance the film through the camera.

    I have two weeks left in the country, I doubt I will be taking this camera on holidays with me....
