Just as the title says, I accidentally connected the 9V DC supply for the arduino into my display instead of the 5V supply I had. After correcting the setup and using the correct power configuration, the display will not show anything from the arduino. Does using the wrong supply even once fry the whole display?
EDIT: I was experiencing no problems with it until this morning when I made the mistake. It was working last night, so I'm almost positive this is the issue.

Yes, over voltage can damage sensitive components.
