Welcome to the HP Support Community!

I reviewed your post and I understand that you are facing issues with the display on the computer.

Don’t worry, I assure you I will try my best to get this sorted.

I recommend you boot to BIOS by tapping the F10 key on startup and check whether you are able to duplicate the issue in the BIOS screen.

If the issue persists in BIOS as well then it is a hardware issue and I recommend you contact support to check the available service options for your computer. You can also test using an external monitor.

If the issue doesn’t occur in the BIOS screen. Then update the graphics driver and BIOS from the below link and check if it helps.

@arunsingh121,

It may be an issue with the display cable or the display itself. You need to get it checked physically to diagnose what part is gone bad.

I recommend you contact support and they will assist you in this regard.

Here is how you can get in touch with support.

1)Click on this link – www.hp.com/contacthp/

3)Enter the serial number of your device or select let HP detect your product option.

4)Select the country from the drop-down.

5)You should see the HP phone support number or Chat option listed.

Cheers!
