I realise suddenly realised a black vertical line on my xps 15 over the right side. It only appear on my laptop screen and not appear on my sedancary screen.
I try lcd diagnostic and EPSA pre-boot system assessment but it still the same.
Anyone can help?
The screen needs to be replaced - or rather, the entire display assembly. If you're under warranty, call Dell for repair.
If not, you'll need to order a screen assembly or have a local repair shop (or Dell) replace it.
