    Quoted from ELA:

    In case I go into the test mode (by the small red buttom in the door) and enter the display tests, all displays are working except the first one.

    1) If you swap display #1 with display 2, in display test does the problem follow the physical display or stay at the first display position?

    2) What do the displays show during game over? Do they cycle previous game scores and highest score to date?

    3) Does the MPU board have any battery corrosion? Can you post clear high resolution pictures of the MPU board?

    4) If you disconnect connector J2 and J3 from the MPU board, does it make any difference?

    5) Have you confirmed good continuity of the display enable signals from the MPU board J4 connector to each display?

    Hi, your first post was clear and I understood it.

    Ok, I just remembered, you must have all 3 balls in the trough outhole area for the game to complete initialisation on powerup. Otherwise the game will sit there with only the credit display showing and will not allow you to start a game (it thinks a ball is stuck on the playfield if it cannot count all three balls in the outhole area).
