How to replace Switch Assembly. This switch assembly fixed the issue. very easy fix. one screw and careful hands are all that are needed. The switch assembly is basically a giant sticker. Peel the bad one off, thread ribbon cables through slits, lign up on the frame and press into place. everything is functioning properly now.
