Hey there belinda201,

It sounds like you have an vertical line of pixels not functioning correctly on your MacBook Pro. I recommend these troubleshooting steps to isolate the issue to either hardware or software, from the article named:

Apple computers: Troubleshooting issues with video on internal or external displays

Reset the system

You can reset the Mac's parameter RAM and SMC.

Reset the resolution

Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:

1. Start up in Safe Mode.
2. From the Apple () menu, choose System Preferences.
3. Choose Displaysfrom the View menu to open the preferences pane.
4. Select any resolution and refresh rate that your display supports.
5. Restart your computer.

Thank you for using Apple Support Communities.

Regards,

Sterling
