Black screen on boot, no backlight BIOS reports “unknown panel”

Texte:

I’m having a problem with the screen, it never turns on, the last time it was on it went blank whitewhite(which is also what it does when I try to run the lcd built-in-self-test), then never came on again, the bios says “unknown panel” I’ve replaced the screen cable but it still doesn’t turn on, and the bios still says “unknown panel”, could the panel have failed?
