A single horizontal line appear on my laptop screen

HP Recommended
HP Laptop 15-da1xxx
Microsoft Windows 10 (64-bit)

A single horizontal line appears on my laptop screen. What happened is that I put it on Sleep mode and after turning it on, I noticed the horizontal line. After countless restart, it is still there. I tried connecting it to an external monitor via HDMI and it does not show the line. I also tried accessing the BIOS and the line is there. My graphic card driver is also updated but the line is still on the screen. I tried print screen but the line is not visible on the image. As far as I remember, the laptop screen did not receive any shock or hit by any object because I put it in a safe place. Please help me. Thank you so much.

The fact that the line does not show in an external monitor rules out problems with the video chip because that would drive both the screen and the monitor.  This means your screen is failing and needs to be replaced.


We are not able, or permitted, to provide any repair estimates or equipment prices.

For this information, you would need to contact an HP Repair or Service Center.

Since you live outside the U.S., here is a link to HP Service Centers, by Country/Region:

If that link does not provide you sufficient information, then use the main HP link:

I've found those links to be unreliable if you're using Win10 and the new Edge Browser; so if you are, you need to use something else, like FireFox.

Good Luck
