2nd GLCD screen not working

I bought a GLCD screen when I bought my board. I didn’t hook up the screen when I put the board in but a few months later I hooked it up. I followed the instructions on line how to hook it up. I could never get the screen to light up. I contacted Cohesion and they sent me a second kit. I hooked it up following the instructions and this one’s doesn’t light up either. Is there something I need to do to get it to work?

The metal brackets you’re mounting it on are probably shorting something out - that’s the first thing I see

When I hooked up the new one it wasn’t attached to the brackets.

doublecheck the connection of the two ribbon cables and the orientation of the breakout board - it’s easy to install upside-down.
