No worries. In case this is your first display replacement, few quick tips…

1. Helps to skim video teardowns like this
2. Take photos of internals of electronics when you open them up so you can reference them later after reassembly.
3. Keep track of screws. Trick: unscrew but leave them loose in the holes of the case tray with pieces of tape over each of them. Then you can remove tray without concern.
4. Bare display edges are especially fragile and often have coatings that scratch easy. Trick: leave protective film on, just put a few pieces of folded tape on edges so you can pull off after install.
5. Your display connects to the mainboard with two connectors wrapped in gaphers tape the right side:
6. Display ribbon terminal (tall one far left) is more fragile than camera/lid sensors (wide one far right). Trick: use guitar pick or credit card to lift clamp right to left, never knife
7. Ribbon itself often has physical tabs or printed white/color blocks indicating seat depth. This makes it far easier to verify its secure before closing case.

Good luck!
