All of our repair wishes are coming true today! Each laser motor mounts to the Lighthouse emitter assembly via four T5 Torx screws, and connects to the motherboard with a single ZIF connector.

Nidec may not be a household name, but we've seen their DC motors before powering fans in the Xbox One Kinect, as well as the Mac Pro Late 2013. These particular motors read: B2044N01.

With the Lighthouse parts laid out for inspection, this teardown is adjourned.
