Black screen : LVDS cable replacement?

Hello, I own an early 2013 MacBook Pro Retina 15-inch. Last week I used a rotary tool to remove two stripped T8 screws so that I could tighten my loose hinge. While proceeding with the tool, I accidentally hit the LVDS cable which was close. You can see the extend of damage here:

Since, I have a complete black screen with no backlight. The computer is starting, I hear the startup sound but nothing is showing. Could replace the LVDS cable fix this problem? Or could it be something else?

There is also this strange thing, when I plug the charger into the mac, it automatically starts with the start up sound, I don't have to push the power button. I didn’t have this issue before.

Could it be a logic board problem or could it be the LCD display itself ? It would be a nonsense to replace the LCD display of a seven-year-old computer even though it’s software still runs perfectly.

Thank you in advance.

You do have a bit of a dilemma!

Clearly the cable is damaged and if you tried using it you could have damaged things within the logic board. So you’ll need to make the effort to replace the display cable. You should be able to replace the cable from the bottom its tricky, but doable!
