I have experienced a switch matrix problem. I thought it was that.
But now, it is so strange to me, that I initiate a new thread.
When I switch on the machine, I receive a message "warning, miniplayfield ..." the same kind of stuff that you get when you open the coin door. The history of the problem shows that the whole row 2 seems to be short in test, and it is not due to the boards.
So, I switch on the game, "test report", "Warning minipf" cannot start a game.
After 1 minute, everything goes back to normal. The minipf makes its self test, the "Free play" message is displayed, I can start a game, and everything goes perfect.
I am wondering what it happening !@?&(!
Does someone have an idea ?
Thanks in advance.
