My Acer Chromebook Spin CP514-1H-R4HQ screen is almost completely dark. If I shine a flashlight on it, I can barely see enough to login. It does successfully connect to an external monitor with an HDMI cable. I have tried the brightness keys, but it does nothing. Moving the brightness bar in the settings menu does nothing. I have tried opening and closing the screen the full rotation, but it hasn't helped. I have tried resetting, but no luck with that either.

The chromebook is 2 months out of warranty. =(

I hope someone here has a suggestion for me. Thank you in advance!

    That sounds like the LED backlight has failed. Since you are out of warranty it's worthwhile to open it up and verify it's not just an issue with the eDP cable. There are ten screws that hold the bottom cover in place, remove them and pry the case halves apart gently. Disconnect the battery cable then disconnect and reconnect the EDP cable several times to try and wipe any corrosion off the connectors:

    Thank you. I will try that!

  • The voltage related to the backlight must be missing in these connectors:

    The correct thing to do would be to check these voltages using a multimeter and electrical diagram. I advise sending it in for repairs.
