Ok, back to removal and repair. The next thing to do is disconnect three connections. First is the
ribbon cable at bottom left, it disconnects from the side that is attached to the larger “green” board.
Next is the two power connections, one at the top of the board and the other at the switch at the rear
of the chassis.
I like to reconnect things the same way they were originally connected so I used a felt tip pen to mark
a letter “T” on the top wire connection to the switch. (Left picture)The power plug already had a white
dot on one side so I made a mental note of it. (Right picture)
Note, the ribbon cable connector is keyed and will only go back on one way.
Use care disconnecting these three, a gentle rocking back and forth while pulling will allow the
connections to come off easily. Do not pull the wires, grasp the connectors.
