Laptop Questions? Ask a Laptop Technician for Answers ASAP!
Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.
Initially, have you tried manually adjusting the screen brightness?
And as a final attempt, have you tried the Fn key with the F6 key ?
Then it would be an internal hardware issue.
Are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter (and even perhaps a soldering iron)?
The most likely suspect would be the backlight inverter. Something like the part shown HERE.
I realize that the above information may perhaps be not what was expected. Unfortunately, there is no quick-n-easy fix and neither is there a workaround; sorry for having to be the bearer of bad news.
Still, good luck and thank you for the opportunity to share the information.
My participation is strictly limited to technical, repair and/or installation issues.
