Multiple vertical color lines on the left side of the display

[tensor]

My laptop screen is showing multiple color lines vertically on the left half of the display but right half of the display always works fine. Theses lines are inconsistent sometimes it disappears on moving the laptop screen or twisting the display. I connected my system to external display but issue doesn't exist on the external display. is this cable problem or display?

@tensor & @sruthivs64 Welcome to HP Community!

I understand that you are getting the vertical lines on the left screen of the display.

What is the product number of your computer? (Ensure you don't share any personal information such as serial, phone number, email ID, etc..). 

If you haven't, Please try an alternate monitor to understand if this is either a hardware or a software failure, 

if the issue does not appear on the alternate monitor, you may need to replace the display assembly on your computer, 

if the issue appears on the alternate monitor/TV as well, re-install the graphics card drivers & update it from the official HP Website: Click here 

  

If you don’t have an alternate monitor, I recommend checking if the issue appears on the BIOS screen (restart the computer and tap on F10 to access BIOS) 

If the issue does not appear in BIOS, reinstall the graphics card drivers & update BIOS using the above link, 
If it does, you may need to replace the LCD/Repair the computer: 

  

If the issue occurred after an accident (such as dropping it on the floor, liquid spilled on it, etc.) there could be a hardware failure and in such cases, you may need to get the computer repaired via HP (there could be a charge involved if the PC isn't covered by the accidental damage protection plan) 

  

Reply with the result of the above-mentioned steps, for further assistance.

I do have the same question

I connected my Laptop to external monitor and there were no issues while using with external monitor.

So I think it is the problem within my laptop display 😞

How much it cost to replace the display of this Laptop or is this a problem in LCD Cable?

If the external display works fine then it would be an issue with the laptop .
