Hello, i've got a Dr Who in good shape, but since i move it in my basement, i created some issues.
First, i had reboots, which where fixed by fixing better the driver boards which was unscrewed.
Now the game is running perfectly and stable as long as you are not launching a game directly after cold boot.

If you do so, the plunger and the vertical eject coils are totally weak, the launcher doesn't even manage to throw the ball to the end of the alley.

If i boot the machine and wait some minutes, the game starts perfectly well without a glitch.

Any idea ?

Thanks to all

It still sounds like a bit of a connection issue especially earth related. It might well be worth going through the earth straps and connections to those wherever they occur across the backbone and playfield.

Best of luck.
