If your machine is still covered by AppleCare simply call them and arrange a repair. Costs will vary based on location and vendor and the issue.
BTW there was no screen shot.

Thank for the reply - not covered under AppleCare or warranty - didn't include the screen shot just mentioned as an additional fact that it probably not a loose cable etc.

A screen shot is 100% software. If memory serves me to get one its Shift Command F3. The use the forums tool for integrating into your post.
Have you run Apple Hardware Test in Extended mode? If not do it 3x back to back. If an error code appears take that with you on your visit to the Apple Store or AASP. Apple does not publish these codes only the store or AASP can accurately translate.
Good luck and By the way next time get Apple Care, small investment but huge return on issues like this.
