Pretty much what it says in the title, I replaced the logic board using the instruction guide and everything went as planned, but upon powering on, I see the blinking question mark folder.

In your case the logic boards static PRAM data is looking for the drive it had before or if it’s a new logic board it’s not set.
Here you need to first leverage the startup disk control Option (⌥) from your keyboard to then manually select the drive, then after it has booted up go to your systems preferences to set the startup disk so it’s set.
Reference: Mac startup key combinations
