    Hi, this is my first time posting to this group. I've done several
    searches looking for any instructions or tips on how to replace the LCD
    on a Minolta Maxxum 7000 and did not have any luck. What I have found
    is that this camera is pretty much disposable, the LCD has a known
    shelf life of about 10years and that repair costs (if you can find
    someone to repair it) will far exceed the camera's worth.

    I have found a few 7000 bodies on ebay for cheap that appear to have
    clear LCD's.

    Has anyone tried to replace the LCD themselves? Do-It yourself
    instructions or guidance would be what I'm looking for.

    Thanks in advance for your help.

  2. On LCD replacement in general: it depends on the how and what of
    replacing.

    The LCD glass is held to a circuit board with a metal clip and
    connections between the LCD and the circuit board are made with
    'zebra strip'. Popping the clip off and then trying to get a
    new LCD, zebra strip and circuit board to line-up again so the
    LCD works is nigh impossible without a factory fixture [or
    reasonable facsimile] for aligning all the parts as they
    are reassembled. With lots of patience and lots of luck
    it can be done, and sometimes even most of the LCD segments
    still work after all is done.

    The thing to do is replace the LCD and the circuit board at the
    same time.

    However ... Cameras, since space is tight, use flexible
    circuit boards made from plastic sheet - about the
    thickness used on report covers - with copper foil traces. One
    or more large flex circuits run all over the inside of the
    camera and have all the switches, displays, ICs and electronic
    components soldered to them. Replacing the whole of the flex
    circuit will be a massive PITA and will require surface-mount
    solder re-work equipment [figure in the $1,000's for the tools].
    Replacing just the LCD with out the proper factory fixture
    will be a very hit or miss affair.

    Sorry to say, I can't be encouraging in this matter. However,
    if you like fiddling and don't mind the possibility of tossing
    the whole shebang in the trash, give it a go. Pop of the LCD
    clip and give it your best shot.

    As to how to get inside the camera ... I can't be much help.
