Could try removing / reseating the ribbon cables . Sometimes works .

Is there any dots at all in the line coming on ? If not it could be a broken solder joint at the edge of the glass which can be repaired by a tricky resolder or use a conductive epoxy to re-join it . Usually the break in the pin is right at the edge of the glass .

Do you have another machine of the same era ? Could try changing out the DMD to another machine . If the problem stays on the DMD then the problem is somewhere on the display itself . If it lights up OK in another machine then the problem is on your driver board somewhere .
