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.

On the this repair it is not necessary to replace the whole IC.  One option is to clip pins 6,7,and 8 on U49 and attach a NPN transistor such as a 2N4401,  base  to pin 6, collector to 7, and emitter to 8.

thanks for the info, i don't think i can do repairs on these old boards(no confidence). i have sent these boards out for repair by professionals. hopefully everything will work out well. again thanks for the response.  bill

Billzel, who do you use for board repairs?  I have a working CEI poker machine, but if something happens to a board, a reference would be handy.
