Hi @randyphilipps,

Welcome to the HP Support Community. 

I'd like to help!

To provide you with an accurate solution, I'll need a few more details:

Have you recently made any software or hardware changes on the PC before the issue started?

Did this happen after a power surge or power outage?

In the meantime, let's try these steps here:

Perform a Hard reset on the PC: 

Completely resetting the computer can resolve many issues that cause a blank screen. Follow these steps to perform a hard reset:

Turn off the computer.

Disconnect all peripheral devices and remove all USB devices and media cards.

Disconnect the AC power adapter.

Press and hold the power button for at least 15 seconds.

Reconnect the AC power adapter.

Turn on the computer.

If the blank screen issue is resolved, you are done.

If the screen is still blank, continue with the next step to listen for computer beeps and look at the lights.

If this doesn't help, It seems like the LCD may have an issue, I recommend you check with an external/alternate monitor connected to your device,

If there's no display on the other monitor (or you don't have another monitor) as well, check if it works on BIOS (by tapping F10 during restart) and then on safe mode to reinstall the graphics card drivers, however, If the other monitor works or has a display, it would confirm an LCD failure and I suggest you Contact HP to have it either repaired/replaced:

Hope this helps! Keep me posted for further assistance.
