Gy-HD100EMonitor tech problem
 

I have replaced the LCD assembly in the flip out monitor on my GY HD110E.
The original worked fine but had a damaged black area which obscured part of the picture
This replacement doesnt seem to power up but the Viewfinder eyepiece momitor works fine.
The spring connector at CN901 broke. Not sure how it reassembled.
Does anyone know the connectivity and function on the Back-light PCB (M BL ASS"Y CK280200A1) for the flip out LCD monitor of connector CN901.
Does this earth to the swivle mount for the whole LCD monitor OR tie the PCB to the back-light assembly and the LCD or do something else
