I suspect all the wiring will be very similar to that in a notebook or netbook - that is have plugs on the ends of some sort. I am also assuming most of the 'works' is on the e-ink side with the LCD side being very similar to a netbook screen with camera plus the added buttons and touch circuits.

If that is in fact the case it should be quite simple to repair, just as I've replaced the fractured board to screen cable on my notebook - about a half hour job including the fact I didn't know how it came apart.

It should be possible for you to get a quote for repairs from some independent repair shop.
