Check the fuse on the power supply, also if your handy with a soldering iron, reflow the flipper board. I have a Laser Cue and went through the same problem! Reflowing the flipper board fixed my problem!

Check for voltage on the flipper input on the board, it's the far right connector in your picture. 2 wht-grn wires and 2 wht-orn wires, should read 48vac according to my schematics. If it does, then check your output, far left in your picture, should be 50v, report back your findings. And if I am missing anything, people feel free to point it out!
Pull the fuse out when checking. Did you have any voltage on the input? Don't go cutting anything just yet! If you have voltage at the input and no voltage at the output pins then you have a problem on the flipper board. Is this what you have found out?
Yes, that way we will rule out the flipper board or confirm the flipper board is the problem! Another thing to check is the flipper relay on the MPU, hold your finger on it and see if you feel it click when you boot up the game! Another question is how do you batteries look? Any corrosion? Any damage to the MPU Board? I ask, because these are all things that I dealt with on my Laser Cue. Don't worry, we will get it figured out!
Quoted from cody_chunn:Disconnect J4 and probe the connector pins inside the housing.
I can't make out the AC voltage that's supposed to be there, but you should see whatever VAC is printed there. Do you?
It's listed as 48Vrms on my schematics.
