Quoted from PinballManiac40:
If your DMD draws too much current, this 0.5 amp fuse will blow out.
There is a 8 pin connector on the DMD that you would need to remove to see if the 0.5 amp fuse blows out. The 2 pin red/black connector on the DMD controller board is only 5 volts going to that board.
Did you have an original DE power supply in the game? If so, what was it doing?
no i had a rottendog but i changed to xpin
my JP had somethimes in bussy dmd secuences when using 2 right flippers, i had some flickering in dmd images
it looked like a power problem so i changed to xpin powersupply.
but even with all dmd cables unhooked, when i power up imedeatly the 0.5 fuse blows on xpin
and now when placing back in rottendog dmd only gives some static
but there's no blowing 0.5 fuse on rottendog powersupply.
with both bords pinball plays
but with xpin everything seems a little more powerfull/snappy (t-rex,flippers,slings,bumpers etc.)
this is my dmd now
