I have recently purchased a wwf royal rumble pinball machine and I am having issues getting the dmd to display a picture.
I have switched out the dmd with another and still no picture. The dmd rom board seems to be heating up quite significantly also (when I touch it, it almost burns my finger).
I have checked ribbons and this hasn’t made any difference.
Does this seem to be a rom issue? Could it be related to earthing or something similar? When I did press down on the rom board I have got some pixels to display which I believe could indicate the dmd is ok?
Any help would be appreciated.
