That's your game CPU not booting. Check the power supply to CPU connector, reseat eprom, is led 201 on the driver board flashing? This is not a dmd problem.

Down the rabbit hole.
You never needed the 12V for the displays and there initially was NO problem with your DMD, it was the CPU not booting. Now somehow the display or display driver board has been damaged so now you have 2 problems.
I would call in a tech to figure it out at this point. Best bet would be to test the DMD driver or the DMD in another game to see what else is now broken. Once you get the DMD booting to the test screen again, then you can try to figure out why the CPU wasn't booting.
