Lulzbot mini converted to lcd and mini rambo upgrade no working


I purchased a 2nd hand mini and then purchased an LCD screen to control it independently.
The mini rambo didn’t have the outputs for the LCD screen so i purchased the updated mini rambo board and plugged it in as directed in the instructions.
I plugged it in and the LCD now flashes and clicks. I updates the firmware and restarted the printer but it is still doing the same thing.
I have swapped the p1 and p2 wires around but got nothing at all that way.

I’m a little tech savvy but not full nerd so basic tips would be great lol.

Any help would be great thank you.

I’m having similar issues as well, posting here to follow your results.
