Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, for test purposes; have you tried connecting the MacBook Pro to an external monitor?
Offhand, it would appear to be a screen problem and using an external monitor would serve as a test and to confirm.
Perhaps the video HERE may shed insight.
Please post back how you would want to approach this and/or should additional information be needed.
And as posted above, a likely internal hardware issue; i.e. a failed screen.
Are you then considering a DIY (do-it-yourself) repair approach?
The symptoms described are rather specific hence the likely suspect is likewise specific and rather than provide false hope, the above test was proposed.
Still, hopefully an alternate approach can be provided by other members of the site.
The question would be re-opened as I would rather opt out.
Good luck with the MacBook Pro.
The question has been placed back in the 'pool' hence viewable by all other members of the site.
My participation is strictly limited to technical, repair and/or installation issues.
