Title: cei poker problem Post by: billzel on December 16, 2009, 06:19:26 PM i have a cei poker machine with 904 board , the 5 hold buttons fail to respond, can anyone help
Title: Re: cei poker problem Post by: dormi on December 22, 2009, 04:02:36 PM There is a common wire for the hold buttons. Common switch wire "C" connects to board at P101 pin 19 through panel 4 pin 1 (J204). If OK game board IC CA3183 switch common is probably bad.

I have a working CEI poker machine, but if something happens to a board, a reference would be handy.
