Quoted from joelw23:Flipper board and ppb tested fine in the other machine
It's an original DE flipper board.

I missed that. This is odd.
New ribbon cables and seems all boards and test good in another machine.
Can you borrow the DMD from your friend's game to test in your game?

dmd tested good in the other machine as well, so i don't think it pays to get his dmd to test in my machine...
Any other ideas?
transformer? cabinet wiring?
I checked the cabinet wiring and found a couple wires melted together, pulled them apart and elec. taped them, but it didn't fix the issue. it was the grey & grey/white wires for the 9v.
I know I would recap the power supply, more so for the reason of the smaller ones do like to leak and cause major damage to certain areas of the board.
I never seen what CN1 looks like on the power supply board. You mentioned you repinned the burnt connector of CN1. Normally, Both connections get damaged.
Slight burn as you can see on pin 12 from the discoloration on the CN1 connector on the power supply.
I am just not quite sure with all the board swapping you have been doing is pointing at a data issue or a voltage issue. I know I always tackle replacing damaged parts/connectors/old power supply capactiros and see where I end up at.
Probably won’t help but worth a try.
My DMD on turtles went weird i had to reset the chip in the board and it fixed the issue same thing with sound. I think the board has cold solder joints i need to reflow the connections.
Maybe your experiencing the same thing. Try to reflow the connections for the chips.

All boards were tested in another game.

With the check point roms?
Quoted from scott_freeman:I would look for AC leakage into DC circuit (bad rectifier)
thx I will look in to that.
Quoted from gutz:Did you replace the melted/damaged wires coming into the power supply?
Didn’t replace, just separated and electrical taped
Quoted from V8haha:With the check point roms?
Yes, checkpoint roms

Those wires need to be replaced, the wires are internally damaged if they got hot enough to melt the insulation. Double check that the correct fuse values and types are installed. Im guessing someone overfused the circuit and the wires melted.
