Nokia 3500 Classic LCD screen
Tools required for disassembly: Torx 6 screwdriver
First remove the battery cover, battery and sim card. Next remove the two screws
you see

Run your fingernail all the way around the join of the front cover
to unclip it.

Your phone will now look like below. Now remove the four screws you
can see.

Remove the main board from the housing.

The LCD is held in place by a metal frame which is held to the PCB
with clips around its edge. Unclip the frame but be aware that the LCD
is still connected by a ribbon in the top right corner. The LCD is held
in the frame by one clip on each side. Release these clips.

You should now have the metal frame removed and the LCD will still
be attached to the circuit board of the phone.

Turn the circuit board over. A small metal box surrounds the ribbon
you need to unplug to release the LCD screen. This box can unclipped
with a fingernail.

Your phone should now look like below. The ribbon you need to detach
attaches like a plug and socket. Simply lift it up to unplug it.

You should now have the LCD screen removed and you can replace it
with your new LCD. Reverse the whole procedure for reassembly. If you've found this disassembly guide useful, please support formymobile.co.uk and order the tools and parts you need from our site. We ship worldwide!
