Flashing Black Screen

[johnieceadkins]

Hello, My laptop has started to flash black when I turn it on and it doesn't stop until I restart the system. Its becoming a constant annoyance so I'm hoping someone can help me with this issue as I've already tried the system check on my laptop and everything passed somehow. I have updated to the newest update because it started the issue and it didn't fix.  Also I have a HP Pavillion if that's needed! Thank you in advance!

Hi @johnieceadkins,

Welcome to the HP Support Community. 

I'd be happy to help you! 

I understand that you are facing issues with a black screen. 

I reviewed your brilliant troubleshooting and extensive research done here.

First off, we need to isolate the issue to correctly to being hardware or software-related.

For better clarity and to assist you better, I would require more information regarding this.

• Did straight out of the box or after a software or Windows update? Do you remember?
• Did you connect it to an external screen such as a TV using an HDMI cable?

Please check in the bios if it flashes black to isolate the issue further. Steps to go to bios:

• Then please go to the bios page and load bios defaults.
• To do this, please keep tapping the Esc key gently several times as soon as you power on the computer.
• It takes you to the startup menu.
• Then press the F10 key to go the bios.

Then check if it flashes in the bios. If it does then the issue is hardware-related and the unit has to be serviced or returned. If it does not then please try these steps:

• Right-Click on start button> click device manager> expand display adapters>then select the display drivers that are listed and right-click on it and uninstall the drivers.
• Check the box that states delete the software for this device.

Then restart the computer and update the bios chipset and graphic drivers from this link: http://hp.com/drivers please select the country and type the product# of the unit.  Then follow the on-screen instructions. This should do the trick for you if the issue is not software-related. Please keep me posted. I will keep a watch for your reply.

Try updating the Bios. CLICK HERE. If not done already to F.45 Rev.A

If the display blanks in the bios, this is a hardware issue and it needs service. 

Keep me posted for further assistance.
