Default [Q] Screen problems with LG Optimus

Model: Optimus G LS970

So I did a little googling, and apparently it is or was a widespread problem.(?)

The problem is the screen doesn't recognize any touch input at all after booting.

People reported that rebooting the device fixes this, but it doesnt work for my particular device.
It boots fine, but no touch capability. It hasn't had any water damage, maybe slight damage from being dropped, but nothing major. The glass isnt even chipped.

My question is this, Assuming that a factory reset/update (via Odin) fails to fix it, will replacing the digitizer fix the issue?
Haven't really tampered with anything yet, dont want to invest in a digitizer if it wont work.

Any info is appreciated, thank you!
