Dec 18, 2013 10:31 PM in response to Vivek21by mende1,It is probably a display or display connector issue. To check this, take a screenshot of the display by pressing Command, Shift and 3 keys. Then, open the screenshot created in Desktop, and see if the line appears. If not, it is a display issue.
If you have not got a MacBook Pro with Retina display, you can repair this yourself. You just need to look for the display connector of your MacBook Pro model in the Internet and install it, and if this does not work, you have to replace the whole display.
However, if you do not know a lot about computers or your Mac is in warranty, you should take the Mac to an Apple Store or reseller to get it repaired
