Was the battery disconnected from the motherboard when the EDP (video) cables were being replaced?
Check if there's voltage on pin 1-3 of the EDP cable connector on the motherboard.
If there's no voltage check if motherboard fuse # FG3301 (3A_32V_ERBRD3R00X) is OK and not blown.
Here is a composite image showing the backlight power supply circuit that may help.
