Default No center display

So, I may be coming into possession of a 91 6 spd convertible. From what I've been told, it has unbelievably low miles and hasn't been started in around 30 years. It has been in climate controlled storage up until 2017 and now sits in a 3 sided shed.

I recently got access to it check it out. I wanted to see how many miles it had on it, so I put a jump box on it to get the display up. Everything lit up, center display backlight came on but no characters. Also, decided I wanted to see if I could get any sign of life, so I turned the key to see if I could get anything. Nothing but the brake light lighting up on the dash.

My first thought is to check wiring. There wasn't a whole lot of rodent traces but they were there. After that, where should I be looking?

Oxidized electrical contacts/connections (including grounds). 30 years is a long time, even in a climate-controlled environment...

I drove over a bump yesterday and the center went out.

I smacked the dash and it came back.
