AHT knows what it knows... so you have a video controller hardware issue. On laptops these are not DIY replace/repairable. If you have Applecare use it... if not you're looking at a DIY replacement of the logic board (advanced DIY).

Its the screen, it looks as if it had an excessive amount of pressure put on it.
Hope this helps,
