After spilled peppermint liquor the backlight from display doesnt work

I hope that you cleaned and dried the MacBook for at least 72hrs before applying power.

Cleaning the logic board top and bottom (soft brush, contact cleaner &99% iso-alcohol) MAY still revive some of the functionality if there's no obvious burn or scorch marks on the logic board.

Otherwise you'll have to

1. live with it as is you can add a usb port expander (self-powered is best but a PIA with a laptop)
2. replace the logic board
3. part out the machine

Remember to return and mark accepted the answer that best solves your problem.

Good luck,
