flexible pcb repair

Hi,
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,

Sean

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:
