Installed inverter cable now boots up with white screen
My macbook had a problem with the backlight. I was only able to see the desktop with a flashlight. I followed the guide on ifixit replacing the inverter cable. I put everything back together, made sure everything was in the right spot and snug, and turned it on. Now I hear the chime when it boots up and it goes to a bright white screen. After 30 seconds or so it shows another white screen with blue vertical bars down the screen. At this point I'm able to use the keyboard sound buttons and screen brightness.
It all worked fine besides the backlight problem before I installed the new cable. Any idea what could have gone wrong?
This is what it looks like after it fully boots up:
I've also replaced the LCD screen with a brand new one before I replaced the inverter cable. I'm positive it wasn't the screen because it had the exact same problem as before..
