Broken screen (LED does not light up) help

Question

ok..
so i have a macbook 13.3 white.. im pretty good with computers/etc..
So i turn on my macbook and the screen is dark.. but surely the macbook is on.. you can see the screen under bright light shined on the screen.
But the screen does not light up.
So i checked- my brightness settings.. then set power settings to normal.. set it to sleep and woke it up. NOPE.
I bought a new screen and installed it properly. NOPE same thing.
I bought a new power 'inverter'.. NOPE same thing
I bought a LVDS cord (chord connecting screen to the logicboard). NO same thing!
So at this point im real close to throwing it as far as i could from the side of the Golden Gate Bridge =/. but i refuse to.
I KNOW THERE IS A SOLUTION AND SOMEONE OUT THERE TO KNOW!
please help, and thank you much.

Definitely follow this advice. Makes life much easier. As for the code itself, first be aware that you can't just "sh" it. It runs using arguments, so you'd run something like
# ./enlighten increase keyboard
Though I wrote that script for zsh, I believe it should be compatible with bash without issue. Below is a much simpler version of the script which will only increase or decrease the keyboard backlights:
#!/bin/bash
#<- Configuration ->
kbd=/sys/class/leds/toshiba::illumination/brightness
kstep=15
self="$(basename $0)"
#<- Error Handling ->
E_HELP=44
E_PERMS=45
#<- Function Declarations ->
permissions () {
if [ "$UID" != 0 ]; then
echo "$self must be run with root privileges"
exit "$E_PERMS"
fi
usage () {
echo "Usage: $self [-h|--help] <increase|decrease>"
exit "$E_HELP"
update-kbd () {
permissions
sudo tee "$kbd" <<< "$new"
exit 0
#<- Run Contents ->
case "$1" in
-h|--help)
usage
increase)
current="$(<"$kbd")"
new="$(( current + kstep ))"
update-kbd
decrease)
current="$(<"$kbd")"
new="$(( current - kstep ))"
update-kbd
usage
esac
Assuming you have the correct file being pointed to, you should be able to just run (assuming you keep it named "enlighten")
# ./enlighten increase
Let me know how that works for you.
All the best,

Ok so i copied that script, and tried to run "./enlighten increase" but it said i needed to be sudo, so i did it with sudo, and it said "sudo: ./enlighten: command not found"
Then i just did 'sh enlighten increase" And this time it gave me:
enlighten: line 29: `update-kbd': not a valid identifier
I have no idea what that would mean.
When i google "`update-kbd': not a valid identifier" all it comes up with is my topic lmfao. Not much help there.
