    So my tmnt needed a rubber replaced, of course it was deep under the ramp so got it all replaced and booted up a game just to play, in middle of game machine just stopped responding, all lights on, no screen. Turn it off and wont boot back up. Wait a bit and it will come on, not kick a ball out and when you press the left and roght flipper it activates the auto kicker. Thought maybe i crossed a wire but looks like where i was messing with it isnt the case. Still new to pinball repair and have a very basic understanding of electronics but im lost :/

    You grounded something. I assume to pull the ramp you had the playfield raised or other...

    I have to assume you failed to turn the game OFF first before any maintenance.

    The video does not provide much information.

    "Start simple, be methodical, work forward."

    Check for any obvious wire shorts in the areas you worked on. Next step, test all fuses to identify suspect areas and narrow the problem. Then narrow to wiring and direct assemblies.

    The MPU is booting, and almost reaching game over sequence. Most likely driver board fusing.
