From the images, it seems unlikely this is a software issue, although to be sure, you may want to connect it to an external display first, to test it out.

If the external display gives you the correct output, then there is a hardware fault. The common culprits are the display cable connecting the display, and the display itself. In either case, if the laptop is still under warranty, you may be able to avail a waiver in parts.

If the unit is not under warranty, I'd suggest you go to a third party repair shop. You will be able to get service for a fraction of the cost. Although, if you are feeling particularly adventurous, just open it up yourself. Google is your friend!

Cheers!
