Vertical lines on laptop screen

[Duncan16]

I have received a Laptop with vertical lines on the screen for repairs. I attempted to re-seat the screen cable on the main board and now the screen is black/dead. My next step is to plug in an external monitor to rule out a main board issue. Any other suggestions please as I need to quote my client. 

Regards,

Duncan

Yes, connect an external monitor and check if that works.

If not, that should be a hardware issue.
