Laptop screen shows vertical lines
My Toshiba Satellite P55W-C has vertical lines appearing on the screen.
The lines are always visible after booting into Windows.
They do not change when I move the screen angle.
I have tried reinstalling graphics drivers but the problem remains.
Is this likely a faulty LCD panel, display cable, or GPU issue?
What should I check first?
