Damaged display cable, Is it worth swapping it or trading in device?
So, my display on my MacBook would randomly go to black and and I believe the problem comes from a damaged flex cable. How can I replace it?

Before jumping to the wrong conclusion, how about fully diagnosing the problem first.
I would start off using a flashlight shining it into the display. You'll need to hold the flash light on the glass at a sharp angle to hopefully see the faint image of your desktop and icons. Do you?
Using an external monitor are you able to see the desktop and icon's when the internal display goes out?

Yes, I see a faint image of the screen when lighting a flashlight to the screen
That would mean the backlight circuit has issues. You'll need to get the schematics & board layout drawings to troubleshoot this as its more likely a component issue on the logic board.
Thanks Dan, but at that point, I’m better off trading it in.

Does the screen randomly go to a lit up black screen? There is a common CPU issue on these where it will usually do that and restart, sometimes showing some pixel width slightly diagonal lines going down the screen.
To replace the LCD cable (not guaranteed to fix your issue), follow the below guide. Step 28 shows the LCD cable (unscrew the PCB and it unplugs from the other side), you can ignore a lot of the steps before this (removing the audio board, etc) since you don't have to remove the whole assembly.

No, the screen does not go to a randomly lit black screen
