Hi Chris..ok I have to ask...you didn't drill too far thru the damaged screw and hit something? Is the replacement screw you used too long or too short...is it touching a ribbon cable? I have to ask.
Next thing is to inspect the ribbon cables for nicks. Very easy to nick one or put a small tear in one. If this happens the usual repair procedure is to jumper the damaged traces...but we'll get to that later if needed.
Inspect all connectors and ribbon cables (with some
magnification glasses or
eye magnifier loup), inspect that they are all seating maybe even try some pressure with your finger on the cables to see if this gives and extra re-seat push while powering it up.
Test the door switch ...manually operate it. Sometimes these ribbons look seated but they are not...this I have experienced more than once.
Do get back on this.
