Hey there @waseemzabi, 

First and foremost, I want to welcome you to the HP Support Forums! Here at the forums, you have many community members that will help you toward a solution with the display blinking. 

Please look at the Image on the screen flickers link and let me know if that is what you are seeing. 

Have you tried performing a hard reset?

Are you using the AC power adapter that came with the computer?

When you turn on the Notebook, does the power LED stay lit? Or does it shut off?

Did you receive any error messages?

Do you have any beep codes or blinking LED lights? 

Have you done a BIOS reset?

Please remove any and all USB devices. Disconnect all non-essential devices, as these could cause some issues.

Please make sure that the AC adapter cable is not plugged into a power strip, surge protector, or secondary power source. It should be directly into a wall outlet. 

Please let me know the detailed answers/results of the troubleshooting provided above. If this reply resolves your issue, please share the good news! Let others know this reply was helpful by clicking the Accept as Solution button at the bottom of this post.

Hey, 

Thank you for getting back to me so quickly. 

Was the Image on the screen flickers link the same as what you are seeing?

Do  you hear the fan running constantly?

Can you see anything on your screen?

Please try the following steps:

• BIOS reset
• Performing a hard reset
• Connecting the notebook to an external monitor

Do you see an image that is not flickering on the external monitor?

Looking forward to your reply.
