Hey everyone!

I have problem with my TZ game. Basically, when I use the plunger and shoot the ball into the scoop, after it pops out of the slot machine scoop if I press both flipper buttons it causes the game to reset (GI goes off, DMD goes off, then it goes back to "Testing...").

I have two LED light mods that light up the scoops that I made myself. I noticed that they can sometimes make a short (the metal wires from the resistor or LED can sometimes touch the metal elements of the playfield, so I covered them with insulating tape). Could this be the reason the game shuts off? I'm guessing something else is up since flippers aren't really related to GI lighting.

That's highly possible since I got the game with one that snapped off so I soldered it back on (with 18AWG wire lol I know shut up... ). It's not even a proper PCB bridge rectifier. I got a few replacement KBPC3502W ordered.

Check your voltages, but low by the sounds of it?

Have that bridge repaired; that sounds awful. And check your 5V. That's what makes games reset. Could be low for a variety of reasons. Don't shotgun this; slow and steady and figure out where your voltage is dropping. Follow the power from the AC input and trace it to the MPU.

Replaced that shitty BR for a PCB KBPC3502W, works like a charm now.

I use kahr's little board until I get around to replacing the BR2 & C5. Works like a charm.
