Question Purple lines - screen issue

[Golgof]

Hello,
I want to buy a secondhand notebook and now I found one, but there's a problem with screen. It does a big purple lines. When you press a place upon the keyboard the lines dissapear. The seller thinks it could be a cable to monitor. What do you think? Any suggestions?
It's Dell Latitude E7240.

If pressure on the keyboard (and motherboard underneath) fixes the issue, then the issue is almost guaranteed to be the cable itself, or the connection between the cable & the motherboard.

Relatively speaking, an easy fix - but time consuming.

Haswell-era laptop... with an i5-4300U? What kind of money are you talking about here?

Ok, thank you. No, it has i7-4600U with 4GB RAM and 256GB SSD and because of the issue it costs only 160$, what's really nice!
