Nokia 6131 LCD screen
Tools required for disassembly: Plastic tool such as a credit card or guitar plectrum.
Run you plastic tool all the way around the join of the cover on the
front of the phone to release it.

You should now have the cover removed. Next you need to disconnect
two ribbon connectors (circled). These attach like a plug and socket.
Simply lift each connector up, away from the circuit board, to unplug
it.

Another ribbon connector needs to be disconnected. Again, this is a
plug/socket type connection. The green circuit board will now be loose.

Your phone should now look like below. Lever the LCD out at the four
points circled below.

You should now have the LCD screen removed. 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!
