PinLED Power Board
As I mentioned in my previous post, to check the power board, I put in a new one from PinLED.
Since this new power board has been in the pinball machine, however, I’ve noticed that at switch on and switch off, that the display shows a random pattern on the DMD, but very brightly, as if with this power board a spike is getting through to the display board. I’m not sure this can be healthy form my display board, so I’m going to enquire at PinLED what is actually going on.
