Laptop screen not working

Idk if anyone on here has any ideas but my screen on my laptop fades to black when i turn it on as of today. any ideas what may be causing it or how to fix it??? thx

either replace the screen, or most likely the lcd inverter.

ok so it works when the ac plug is not plugged in but when i plug in screen fades to black???

Had that happen once before, just go into the bios and load the default settings, then save and restart the computer. that may do it. Seems my bios got “stuck” somehow" Possible power spike…
