I just got a blazing 7's 5500 proslot. put in a battery & reset the game, it went into game mode. Its a 2 coin max game. it was only taking one coin then the rest would just fall through. Now it wont take ANY quarters, I even went as far as bending the rake on the coin comparator to make the coins fall through the optos. If I open the door & pull the door switch open (to make it think the door is closed) I can see the green LED as well as the orange one briefly flicker as the quarters drop through. Even swapped the opto board with a spare I had, same thing. The test button does give credits with the door open.
The dollar bill acceptor DOES WORK, I can close the door, insert a few dollar bills & it adds credits & lets me play. Im starting to think maybe a board problem?
thanks for any advice you can give, you guys have always got me through in the past!
