Lethal Enforcers Reboot Loop After Inserting Credit

Hello,

I'm new to the site, but have been a long time game collector and recently got into restoring arcade cabinets. I picked up a Lethal Enforcers cabinet that I'm not really sure what's wrong with it.

At first, when I turned it on it said "Verify Bad. Please power on the machine while holding the test button". I found the test button behind the coin door, and got it to boot into the game. The I tried putting a quarter in, and the machine restarted. So then I tried it with the player 2 coin op, and same thing...the machine rebooted.

I thought it might be the coin ops, so I found out how to get into the screen where I can change it to free play (by pressing the test button once the game loaded). In there, you can change all the settings and everything, so I went through all the diagnostics, and the coin ops, light guns and the buttons all test out, and don't restart the machine while in the test screens. So I exit to the main screen, press the Player 1 button to start the game and it tries to start (says part of the word "Player One" and reboots the machine again. :(

I'm sure you can imagine my confusion. Since the guns, and all the buttons and coin ops work in the diagnostics screen, why would it reboot the machine when I insert a credit? Something else worth mentioning is that once it does this once, it gets stuck in a boot loop where it'll get to the very first opening screen and then reboot again. It'll eventually get past that if I hold the test button while powering it on a few time and then it'll show the game demo for any amount of time.

Any thoughts that might help me out and restore this cabinet? Thanks!! :D

If everything works okay in test but not in game mode i would start looking at a bad coin meter or switch wiring job that would cause it to reset. Some people put lights on the buttons and they get wired to the swich by accident.
Start by disconnecting one switch wire at a time and coin up and seeing if that narrows it down.
Also go back in test and clear all records and high scores to see if a A.C. surge may have caused internal garbage to be recorded and screwing up your game. Along shot but i have seen it a dozen times on games.

I have tried unplugging the guns/button panel from the rest of the machine and that let it go into the demo screen again, but as soon as I triggered the coin ops, it rebooted again.

I also tried unplugging all the wires going to the coin op and the lights there (no wires running to the door at all. Again, got to the demo screen and when pressing the player 1 start button, it rerbooted the machine.

I wasn't able to find out where/how to clear the high scores from the game from within the test screens, so I wasn't able to test that part out yet.

On a side note, does anyone know what buttons I would need to buy (and where to buy them) to replace the player 1/player 2 start buttons on this cabinet? One of the connectors on the button looks loose, and although I don't think that's the cause of the problem, I'd like to get it replaced.
 
i would stick a multi meter on that thing at see if you are getting a power drop. order your buttons/joysticks from twisted quarter

you could also have a board problem
 
Does the machine pass all the ROM/RAM checks?

If not, you may have a bad ROM or RAM.

Another thing to check... Is the Hybrid IC over by the sound chip OK? If the caps leak too badly they will damage that hybrid and the result can be a game that reboots or otherwise won't start properly. Missing sound outputs is one clue that the hybrid is going bad.
