in the

way, remove it.

Remove the 4 small self tapping board screws (2 at bottom, 1 on metal shield, 1 on edge of board

under fold in top ribbon cable).

Lift the board out complete with side switch panel.

Take great care with the LCD. This may be fixed in some sets but may also hang down by its

ribbon cable on others. Either way, it is easily damaged and will probably attract any dust in the

area.

Again, it is a good idea to remove the adjacent ribbon cable, although this can be quite tricky due

to a strap being soldered across it. Note that the ribbon cables are not interchangeable.

If the solder pads are damaged, remove the old socket and clean up the existing solder pads. Any

damaged tracks will have to be bridged with very fine wire. Each solder pad goes to an adjacent

small ‘plate through hole’ on the board. These are visible on both sides of the board once the

display frame is released from the board (4 fragile clips on board edge).

Depending on the amount of track damage, remove the resist from both sides of the through

plated hole and solder the fine wire though this.

Glue the new socket in place. It will automatically locate correctly on two small lugs. Solder the

pads (or new wire) to the socket.

Re-fitting the board is easy enough. Make sure the display locates correctly and remember to

solder the speaker wires.

Re-fit the ribbon cables at both ends.

Make sure the accessory door is located correctly.

Now the tricky bit, This is the way I do it;

Offer the two case halves together holding the rear case in the left hand holding the earphone

rubber out of the way with the index finger.

Hold the front case with the right hand keeping the power and option socket rubbers out of the

way with third and little fingers.

Push the case halves together making sure that the battery contacts slide into their groves in the

top case and remain in their seat in the bottom case. This can be seen through the gap between

the case halves until they are mated together. At the same time, check that the accessory door

hinge has located correctly.

Re-fit all the case screws and test your work.
