"two purple lines 2 inches apart down the left hand side of my laptop. "

When you attach an external monitor you will likely find that the lines are not there.

This would mean that the Display needs to be replaced to resolve this.

If by chance the external monitor does show the lines, then the mainboard needs to be replaced.  The video chip on this model is part of the mainboard - it is not removeable.

What is an external monitor?

Plug a desktop monitor into the system - that will tell you whether it's the screen or the mainboard that needs to be replaced.

Hi,  I have plugged in an external monitor and there are no purple lines.  What do I do now?  Thanks for your help.

Replace the notebook's display panel with a new one.  You'll need to remove the old one to find the part number, which will be on a label on the back of the panel.
