I doubt the bridge is bad. Even if one or more diodes would be open (rare), there would still be some voltage output, but lower than expected. Before replacing the bridge, which could easily do more damage than good, do a few voltage checks. It's an extremely simple circuit. Check AC volts coming into the board at J102, one probe on pin 1 or 2, other probe on pin 3 or 4. Expect 15-20vac give or take. If that is not there no need to fool with the board, probably the coin door interlock switch would be bad or wire disconnected. If AC volts are there follow the path to the AC pins on the bridge, and make sure AC is there. If ac there, make sure ground to the bridge is connected and see if 20v is coming out of the bridge. If so, but not at the test point, find the open on the board. These things usually crop up when guys replace the capacitors and or bridge and damage the board. For sure don't replace the bridge without doing some checks first.
