horizontal lines across my hp laptop screen

Thin horizontal lines started showing across the bottom third of my HP laptop display. They get worse when I move the hinge. An external monitor looks normal. Is this the cable or the panel itself?

If it changes when you move the hinge and an external monitor is clean, it's almost always the display cable. It runs through the hinge and wears over time. A dying panel usually doesn't care where the lid is. The cable is cheap, but you have to take the bezel off to get at it, so look up your exact model number before ordering.
