Press the start button and eject the ball to reset the game.
I have Johnny mnemonic.

I replaced the power/driver board with a new one.
But still reset.
Power at the test points is sufficient.

I noticed that closing the coin door tightly would cause an anomaly.
All lights go out and a diagonal line appears on the screen.

What is wrong?

The slam tilt switch was repaired but reset.

Is it sometimes a problem that the start button doesn't light up?
When you enter the menu and come back, it emits light.

Occasionally a game, but resets when not hitting a bumper.
What should I repair?
