X) Remove cables and re-attach case and four screws. 
 
Y) test again boot process and with NikonScan 
 
Z) test again a week later and / or burn-in for 48 hours  
 

Appendix A:

  

(to remove the black mechanism assy from the metallic-colored case structural assy) 
 
This additional disassembly may be required to remove the top light source module to clean front 
surface mirrors, both on top and bottom where the lens and sensor module is. 
 
i) remove the four screws on top module, place in vial #5 
 
ii) remove tiny black screw on front corner of structural assy, place in vial #6. Note the indexing of 
the top plate with other screw heads 
 
iii) remove three screws on bottom that attach the black mechanism to base of the structural assy, 
place in vial #6  
 
The whole black mechanism will slide out. This will facilitate cleaning access to especially dirty 
mirrors and lens 
 
iv) reverse procedure for re-assembly. The light source assembly is in elongated sliding slots. 
Fasten in the mid-position.
