Welcome to HP Forums,

This is a great place to get support, find answers and tips,

Thank you for posting your query, I'll be more than glad to help you out 🙂

As I understand, the screen goes blank, 

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?

Are you connecting your PC to an external monitor?

What is the On-screen message that shows on the display? 

Have you connected the HDMI cable to an HDMI out or HDMI in port?

Have you checked with a USB Type-C cable to the USB Type-C Thunderbolt port on the computer?

While you respond to that, you could try these steps from the link: Click here

Reset the display

On-screen message shows on the display

Inspect the video cable and video connectors for damage

Check cable connections

Connect the computer to another display

Reset and update the BIOS

Change the display resolution

Disable the power settings in BIOS

Let me know how that pans out

I hope you have a good day ahead,

Have the same problem. Nothing to do with connecting any HDMI cables at all; don't have anything connected by HDMI cable. The problem arrises when trying to boot up the system; an error message appears on screen "Check HDMI-IN cable". Appears that the system is looking for a boot disc that it thinks is connected via HDMI. There is no external bot disc! It's just failing to boot from the internal drive. Solution please.
