There are two slam switches on the game. One on the door and another by the tilt in the cabinet. If these are too sensitive the game will slam reboot. You should examine them and maybe disconnect them to insure they are not the problem.

Lets look in the backbox. Show us pictures of the rest of the boards. What does the LED on the MPU board do when you try and start the game? Check the fuses on the rectifier board too while your at it.

If all the coils die, including the flippers, but the game keeps playing otherwise, that could be a problem with the 5v jumper between pins 13-25 on the SD-J3 connector. When that goes bad or the pins gets loose your coils will quit. A wiggle of the connector will get the coils on and off.

Center target needs a .05 or .047 capacitor across it or it will not register quick hits.

It sounds like the kickout hole is somehow miswired and the game thinks it's the outhole.

None of these should be the fault of the new rectifier board.
