Default 1986 Digital dash problems

My 1986 corvette is having digital dash problems, it was spotty when I bought it but then after driving for a while it started working perfectly(I am assuming it has to do with the ground). I had to leave it to sit for a couple of weeks so I disconnected the battery. when I reconnected the battery the dash lit up but it flashes and does this. Is it a ground problem? Where is it grounded to? How do i fix it?

Push lightly on the upper left corner of the speedo.
behind the face was where the bad solder joint was on my 86.
it should work while you push

It looks like it's continuously trying to boot up. I would check the pin connectors between boards inside the display, for overheating and bad connection. Also could be a power supply problem on the board. Batee.com would be able to fix you up if you sent it to them, but have a look at a few of their videos to see if you can get a hint from any of them.
