Yes - hopefully I have shared enough information that anyone with the necessary electronics skills could carry out this repair. The time consuming part is tracking back to pick-up points for the 64 continuity checks.

Also, the re-connection/replacement of the ribbon cable which links the button/LED board to the main board is quite a challenge.

I would put the repair time at somewhere in the range 2-4 hours.

As you say Mr F, options for the future as and when brand new APBs become scarce and when the second hand market has more APBs with dodgy ports than without.
