Issue with Blue Screen on TDS 2024C Scope

I have a TDS 2024C scope that on power on the screen is blue and then it goes blank. Do I have a bad screen or bad board?

I would assume there is a board problem, or loose cable or, the screen being blue then blank gives some indication the screen is working some.
