Vertical lines on my laptop screen, repairable or done?

back up anything important now, while you can still see the screen. these lines tend to spread, and once half the panel is unreadable even getting your files off gets awkward (an external monitor sorts that, but still). also check the warranty before paying anyone. some manufacturers treat lines like these as a known panel fault.

Plug it into a TV or monitor first. If the external screen is clean, the graphics side is fine and it's the panel or the cable running up through the hinge. Then open and close the lid slowly while watching the lines. If they flicker, move or vanish at certain angles, that's the cable, which is the cheaper fix. If they stay put no matter what, the panel's usually gone. Lines that are also there on the boot logo, before Windows loads, point to hardware too. A panel swap is often worth doing on a laptop that's otherwise fine. The part number is on a sticker on the back of the panel, so get a quote for that exact one.
