I have a similar issue with a board from an IPOD Classic 6. The brown clip that holds the display ribbon in place is broken. Is it at all possible to replace it with a clasp from another board? What are the other alternatives to such a repair?
@krams you can try to replace the clasp from a broken board, but make sure you do this very carefully. The clasp has a tendency of cracking in the middle. The display cable requires the clasp in order to force the cable down and make proper contact. The other way to do it is finding a broken logic board and desolder the connector and resoldering it onto your board. Not easy and requires micro-soldering tools and skills. The only other way is to replace the complete board.
