Screen flashing off and on rapidly

HP Recommended
Pavilion x360

Occasionally my screen would flash off and on; making the laptop unusable. During the periods when the screen flashes on, the display is very blurry. When the screen is turning black, I see little green lines going through the display. Tonight it happened again, and I feel like this time was worse. Last time the issue resolved itself, but today I had to restart the laptop to fix the issue. This only happened twice and both times it happened while I was in a zoom meeting (may or may not be a coincidence). Is this an internal issue with the laptop or a problem with the zoom application?

@ksimp10

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:

  • Did you make any changes on the settings of your PC prior to the issue?
  • When was the last time it worked fine?
  • Have you updated Graphics and Chipset drivers?
  • Have you checked the display on an external monitor?
  • Have you tried with different webcam apps?

While you respond to that, let's try these steps: 

Hard Reset: Follow steps from the link: https://hp.care/2GnkMa8. (Refer to the removable and sealed battery)
BIOS default:(do not skip any troubleshooting steps even if you feel steps are repeating)

  1. Turn off the computer and wait five seconds.
  2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
  3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
  4. Press F10 to Save and    Exit.
  5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
  6. Follow the prompts to restart your computer. 

Hope this helps! Keep me posted for further assistance.
