I have a Nikon Coolpix P7000 with the dreaded lens cover problem. (i.e. the cover did not fully open causing shadows in the corners of the pictures.) I have purchased a new lens assembly and stared to remove the old lens, however on disassembly, I have gotten as far as the main board but I cannot see how to remove the optical viewer assembly. I am also wondering how I remove the front cover, and if that is a step I need to take.
