Lectronamo
Stern Electronics, 1978I have a Lectronamo that plays 100%, but recently the score displays began to flicker when a sound is played.
When the sound completes, the displays are clear again.
This happens on bootup when it beeps (after the MPU startup beeps) and during a game.
Where do I start?
I'll check the sound board caps next.
The same issue occurred before and after a new power rectifier board was installed.
Quoted from c0wb0y:I'll check the sound board caps next.
The same issue occurred before and after a new power rectifier board was installed.
Rectifier board doesn't have the caps on it, they're on the solenoid driver board.
Disconnect the sound board completely (power and ribbon cables). See if the same thing with the displays happen.
What mpu board do you have installed in the game? What displays?
