My Problem

Power lock button didn't work any more.

My Fix

GREAT! Had to back up/undo the reassembly part way through for I forgot to install the position sensor. After that all went well.

My Advice

Wish y'all would put the reassembly steps in the guide step by step for better flow of the project.

This is a very tedious fix, should only be attempted by persons with patients and an eye to details.

Sorry no picture the IPhone is my only camera
