Liquid Damage - Display Working / No Backlight
I have recently obtained an Early 2013 MBP 15-inch Retina, 2.4 / 8GB / 256 SSD. The person that donated the laptop informed me that she spilled some liquid into the machine and that it no longer works. Come to find out the machine boots and runs fine, display works through thunderbolt -> HDMI or HDMI port and LCD, however, there is no backlight.
I checked the fuse labeled "P" below the right fan with a multimeter and I do have continuity. The liquid sensor is tripped under what I believe is the LVDS connector.
Can anyone provide next steps for troubleshooting this bad boy?
EDIT: Board is 820-3332-A
Is this a good question?
