Acer Chromebook cb5-571 screen stays black how to fix

Larsson2014

Hi,
I have an Acer Chromebook 15 cb5-571 and recently I used it until it was at 0%. Now when I hit the power button the blue light at the bottom goes on but the screen stays black. I have tried multiple ways to fix it but none of them work. I even replaced the battery.
Thanks in advance and happy holidays!

Have you tried to press the screen brightness up key? Jack E/NJ

I have pressed the brightness up key JackE. I also checked if the brightness down key was stuck, which it was not.

OK, next, have you tried to HDMI out to a TV to see if the graphics adapter is still alive? Jack E/NJ

I have the same problem as corolady and Larson2014. I have power. tried everything.

OK. Let me repeat. Try to HDMI out to a TV set to see if the graphics adapter is still alive. If no TV screen, then the graphics adapter and mainboard are probably fried. Jack E/NJ
