Nokia N73 LCD screen
Tools required for disassembly: Plastic shim such as a guitar plectrum or credit
card.
First remove the battery cover, battery, memory card and sim. Now
push your plastic shim into the join at the top of the phone to lift the
front cover out slightly. Then run the plastic shim along both sides of
the cover to unclip it at these points too

You should now have the front cover removed, like below.

The LCD screen is held in place by a metal frame which needs to be
unclipped around its edge for removal.

The LCD screen will now be loose and can be removed. It will be
attached to the phone by a ribbon which attaches like a plug and socket.
Simply lift it upwards to unplug it.

You can now lift away the LCD and replace with new. 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!
