Harrisburg, PA
Quoted from phil-lee:Machine boots and plays great. Only it won't advance to ball 2.
When the ball drops, game over flashes and another ball ejects.
Did I tell you the displays went crazy? Flashing wrong high score, segments missing, player 2 stays 00000 all the time.
High score also flashes at end of ball.
Boards have no alkali damage,but are original.
Wanting to play rather than repair right now(save the boards for later) could I just order replacement Alltek? Which boards do you feel I need?
Reading the Pinwiki now, but hoped someone may have had a similar problem and could help.
Cleaned the connectors on the MPU and Driver board, no change.
Check for a bent diode or torn fishpaper on the coin door. A switch shorted to ground on a Bally -35 will do all sorts of odd things like mess with the displays and lights. One way to test this is to start a game, and then remove the coin door connection all together. Just be careful as there is 48VDC on the plug for the coin lockout relay.
