Lethal weapon 3 pinball machine is fully working but the dmd is locked on the version and stay like that I can get into test but I can't see anything because of the dmd does not change battery holder has been replaced and new battery install , I was going to order a new ribbon cable to see if that would change .
Could the dmd be bad ? Or the mpu board ?
Any ideas when really help I really don't want to drag it out the person basement ,
