8 Open the lower cabinet cautiously.

9 NOTE!

Be careful not to damage the circuit board with the opening tool.

With the front opening tool, release catches that hols the main PBA in the case key front. Start like the picture show (1).

If necessary do the same thing on the other side (2). (make sure to avoid prying on the flex films)

NOTE! Sometimes it helps if you bend the frame a little side to side.

To remove the main PBA, lift the camera end of the circuit board away from the case key front as high as it will easily move.

With the PBA in the lifted position, wiggle the board back and forth while pulling the board away from the system connector.

NOTE! Don’t bend the circuit board to much upwards.

11 NOTE!

Always be careful with the “two main cables” (Harness) (1).

Open out the main PBA from the frame

NOTE! VERY IMPORTANT! Remember how the two main cables (Harness) are assembled “with a twist/crossover” to the main PBA

NOTE! Notice the two small “knobs” (2) on the UPPER side on the connector – they must be directed like the pictures shows when they are reassembled.

NOTE! Remove the two cables from their clips (3).

NOTE! Be careful not to damage the two cable connections when unplugging the connections using the dentist hook.

NOTE! Do not pull on the mass of cables that make up

the cable assembly.

At one of the cable/board connections, use the dentist hook to unplug the cable connection from the board. There are two locations that the connector must be alternately pulled at to free the cable from its mating board connector. The

location at the two parallel arrows, are the two pulling locations. The cable should be

pulled towards the end of the circuit board in which the system connector mounts.

Remove both connectors.

Case key rear and circuit board disassembled.

12 NOTE!

When reassembling the two main cables (harness) to the main PBA start like the picture shows.

The left cable (L) should go to the left connector on the PBA (See picture 13).

The right cable (R) should go to the right connector on the PBA (See picture 13).

13 Place the main PBA against the case key front

like the picture shows; start to connect the two cables to respectively left and right ZIF connector.

Take notice of the “crossover” (1).

14 NOTE!

1. Be careful not to damage the two main cables and the connectors with the tweezers.

2. Notice on the two small “knobs” (1) on the UPPER side on the connector – they must be directed like the pictures shows when they are reassembled.
