PIN2DMD and reverse connection of ribbon cable

[Ashram56]

Good morning,

 

One question: did you ever encounter a case where flipping the DMD connector orientation would result into a full pinball reset, and damaging the DMD controller board (WPC) ?

 

A friend of mine installed a PIN2DMD in a Dracula. At first he had no display (besides the PIN2DMD logo), so he thought he had plugged the ribbon cable the wrong orientation, and he flipped it. Instant pinball reset. He put back the original plasma, vertical lines, no signal

 

Test input on the PIN2DMD shows "Pin 11 close". Looks like there's a short on this signal.

 

Can this be caused by plugging the DMD cable the wrong orientation, or is this a coincidence ? (something else broke at the same time) 

 

Thanks

No

He replaced the DMD board and it works fine.

 

It was therefore just coincidence and bad luck that the controller board fried when he plugged in PIN2DMD.
