    I am in a bit of a fiddle as I have a projector worth over $2500 and the
    flexible pcb connecting one of the lcd panels to the main board has broken
    (the gold fingers have been cut off - of course this is due to me opening
    the thing up in the first place so it's my stupidity) - The flexible PCB is
    still long enough to reach the connector but it needs gold fingers on it ..
    I know that technically it is possible to repair this but really specialised
    equipment is necessary.
    Is there a service anywhere in Perth where I can pay someone to fix this
    PCB!? .. I have no alternative as apparently the lcd panels cannot be
    replaced individually and to fix the unit will cost in excess of $2700 - not
    worth it! I hate to see a perfectly good 6month old projector goto waste
    because of one cable breakage..

    Thanks for any advice,

    Sun Industries in Osborne Park make flexible PCBs, maybe they could
    suggest a fix or repair it for you.

    The covering on the tracks can be removed if they are in the right place
    to fit in the connector. It's a separate laminated layer that you may
    be able to remove with care and a scalpel.

    Alternatively contact the service agent for the brand and get a new
    board fitted.

    Here's another method using 3M Scotch 9703 conductive tape:

    "Tape 9703 is an isotropic, electrically conductive, pressure
    sensitive adhesive (PSA) transfer tape. It is a permanently tacky
    system consisting of a PSA matrix with aligned conductive particles.
    These particles allow electrical conduction through the adhesive
    thickness ("Z-axis"), but not in the plane of the tape."

    More Z-axis conductive tapes:
