fine vertical lines throughout display

[VS_Laptop]

Hi,

I am having this issue of vertical lines throughout the screen, even when I use the BIOS settings screen, this issue is existing since 4-5 months.

I have factory reset the laptop multiple times, and upgraded the BIOS too, but the lines still persist.

I have upgraded and downgraded the graphics drivers for both the - intel graphics card and nvidia graphics card, but the lines are still visible.

I ahve contacted HP support in India - online and I visited the service centre too, but they were unable to help me resolve this issue!

My laptop is a HP Pavilion DV5-t, 15.6 inch touch screen laptop.

Can you please suggest, if the display is to be replaced? If so, how much would it cost in the US? Can I purchase the display unit in India, as I travel frequently to India?

It may be either display panel issue or display cable connector issue. This is confirming with the symptoms.

Cheapest replacement is cable, costliest is panel replacement and touchscreen means mor shelling out more money for the panel.

If you can provide exact product number, full model name, I could help you with finding the part (s)

Hi,

Thank you for the quick reply!

Product Name: HP Pavilion Notebook

[personal information removed]

Product Number: L9S44AV

I think, changing the cable is the first solution to try, can you provide the part # of the cable? Can you also let me know of a reliable source online or physical store to purchase this part - in India/USA?

Best Regards,
