During my repair, I removed the Rear Operation Unit and Main Printed Circuit Board (P.C.B). However, that requires disconnecting several ribbon cables. It has since been confirmed that this section is unnecessary and can be skipped .

Refer to section 8.3.2 Removal of the Rear Operation Unit of the Service Manual.

If necessary, remove the blue Main Operation Unit by removing its two retaining screws and connected ribbon cable. Note that the bottom of the MOU hooks into place and must be unhooked for removal.

Refer to section 8.3.3 Removal of the Main P.C.B. of the Service Manual.

Remove the ribbon cables connected to the Main Printed Circuit Board (P.C.B.) and its single silver retaining screw, then remove the P.C.B.
