Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• When was the last time it worked fine?
• Does this happen while moving the lid of the screen?
• How often does this happen?

I have a few troubleshooting steps we could try to fix the issue:  ​​​​​​​

I recommend you attempt to access the BIOS screen by tapping on F10 while the computer is restarting, 

If the issue persists in the BIOS screen which is outside windows, it would confirm a hardware failure and you will need to Contact HP to replace or repair the LCD, 
 

However, if it doesn't show up in the BIOS, it would confirm a software issue and we'll need to reinstall or update the display drivers using the Official HP Website: www.hp.com/drivers

Also, perform a BIOS update following steps from this article: https://support.hp.com/in-en/document/c00042629

Keep me posted for further assistance,
