Welcome to HP Forums and Thanks for the post.
I understand that you are facing a display issue on your All-in-one computer.
Not to worry, I will be glad to assist you.
Have you tried any troubleshooting steps on our own?
Request you boot the computer to BIOS by tapping F10 repeatedly during startup.
If the issue persists, in BIOS, please contact our phone support for the service options available.
If the issue does not persist in BIOS, restart your computer and refer to this HP Article and try the steps suggested.
Let me know how it goes.
