Here's the latest. Just a reminder to anyone reading this, myself, beau and per all have similar issues with our games as the MPF flat out died.
We took the MPF off (super easy to do btw) and disconnected the PCB underneath. Under examination there are some scratches on the board that go across several tracers. The tracers are also cut VERY close to the edges of the board. So close that we had to use magnification to see if the tracers were on the edge or not. It doesn't appear that any of them are but I've never seen tracers so close to the edges of a board before.
We then reconnected the MPF to the ribbon cable (aka flat cable) and then all the lights turned on and blinked and flashed as they should in attract mode, but they were obviously dimmer than they should be. Putting the MPF back on confirmed the dimness of the lights, which were less than 50% bright vs the rest of the main playfield.
We then connected just one switch into the PCB and went into test mode. The switch worked, but when pressed it also somehow activated three lights on the board to about 10-40% brightness each time the switch was pressed. We plugged many switches into different connections and each time the switch worked in test mode but the lights kept turning on.
We then plugged the 4-pronged opto plug in and FOUR lights came on at what appeared to be about 75% brightness. They came on right away. It was the same three lights and a fourth light that appeared to be the same exact lights I showed in pictures earlier. The opto did not appear to be working as we couldn't get it to test.
In all of these tests, no other lights in any other part of the game came on, just lights located in the MPF.
We then noticed everything on the PCB connected to a board called PD-LED1 aka "PCBA-0009-0004 MM167", so we took that board off and gave it a look but we didn't see anything out of the ordinary.
BTW, when I say "we", I mean myself and 1-2 techs I work with. I'm just a peon in the repair world, these other two guys are brilliant. One works in the tech industry and can even make electronic parts for games with supplies he has at his work. He's that knowledgeable.
I surmise the issue to be the PCB. Because the other two guys have experience and education beyond my capacity, they couldn't say with 100% accuracy that the PCB was the problem, but when pressed they both agreed that the likely culprit is the PCB.
So.... your move Dutch.
And keep in mind good guys at Dutch that this game is on location and it's been down for three weeks now. I've had people drive HOURS to come play this game only for them to find out it's broken. It doesn't make me look good.
