Check the LVDS connector from Screen to Logic board. Push it in if it's out. If not, then worth getting a new LVDS connector cable, try that out before thinking about replacing the screen.

Take a flashlight pressed against the screen at a sharp angle are you able to see a faint image of your desktop and its icons? If you do then the issue is the backlight logic not the LVDS cable or the GPU board.

Being able to access your system remotely is a good sign as that tells us the main logic board is good
