Can anyone suggest a methodical way to isolate where the problem is?

Find which wire on the connector is not making a connection. Power
off. Attach wire hooks or tack solder some wires to opposite sides of
the connector. Attach an ohmmeter. Now, wiggle things around until
you determine where things are intermittent.

A close photo of the connector area would be helpful if you want me to
make a guess(tm).

I couldn't find 67 - 74 on the main board schematic (Pg 18). That are
the row and column coordinates or maybe a large nearby component?


I think the problem may not be mechanical, as I've noticed that now the
keyboard is having issues triggering as well, which is not connected to
the same area.

I think I screwed something up swapping R66 on page 18 near the LCD, and
the processor is having trouble with read/writes or something.
