The purpose of this guide is to replace the eyepiece (plastic rectangular piece around the viewfinder) of a Nikon Coolpix P90 if it is loose, broken, or lost.
In steps 1-2, 5, and 8, a Phillips #000 Precision Screwdriver is used to unscrew and remove all of the screws mentioned.
In steps 3-4, 6-7, and 9, there are three data connection ribbons which need to be carefully removed before the repair can continue. Failure to remove these ribbons properly will result in them becoming damaged or ripped, thereby permanently damaging your camera. So, please be careful and go slowly during this repair.
