HP Chromebook 14 runs but screen stays black, no video.

HP Chromebook 14  runs but screen stays black, no video.

Summary: After a complete "System Recovery" effort it worked ok for awhile but reverted back to the original symptom of a BLANK BLACK SCREEN.

To see any video at all, I connected a 2nd monitor, via the Chromebook HDMI connectioin. The 2nd monitor showed plain Lt blue video, including some keyboard stroke status for controls like mute, vol level etc when they are touched.   After trying lots of simple web advice (to get video on chromebook screen) nothing worked.  

I manually induced and successfully performed a complete "factory OS reset" or "System Recovery" (Chrome OS).  After all that I still did not get "normal video" on the Chromebook video screen, but the 2nd monitor now displayed the standard pretty factory desktop scene; yet no prompt for completing the System Recovery.

Finally: I shut everything down and quit for the night. Next morning when the unit was powered up everything worked normally for the Chromebook; normal video and  prompt menu ones sees after the OS reset.  BUT, it was not long before it reverted back to the original symptom of a black screen, I'm back at square 1.  Thank you for any suggestions.

Hey @jimichrome,

I see that you are having an issue with the display screen on your Chromebook 14. I can help you with that.

This document outlines how to troubleshoot power on issues with your Chromebook. I know it's not quite the issue you are experiencing, but you can go through Steps 1, 2, and 3 to see if you can get restore full functionality on the Chromebook's display. When you finish Step 3, you can omit Step 4 as there is no reason to perform a System Recovery, when you know the display screen is the issue. Instead, contact HP Support directly by clicking on this link and filling out the form at the bottom.

Please let me know the results of following the document. If you can get the display to function, please click on Accept Solution. If you appreciate my help, please click on the thumbs up icon. Both icons are below this post.

Thank you for responding.  I can tell that my HP chromebook 14 powers up ok, but the screen remains blank and that's the problem I can't fix.  I hooked up a 2nd monitor to the HDMI connector and 2nd monitor displays normal video.

You are going to need to contact HP Support directly for this issue, using the link I provided above, as it sounds like the Chromebook may need to be serviced.

Thanks, but I've already contacted HP support "directly" and after trying the simple approaches to my problem I received a repair quote of $380,   approx.  $100 more than a new replacement. Thx for your help.
