NBA JAM Sound Fuse?

I don't see a fuse for the sound in the manual. You should check all of the connectors on the sound board and verify the pot in the coin door.

TY OZ for the respond. Put in my wrestlefest board in and played fine with sound.

Trying too figure out why 1069 system all of a suddan went Mute!

Jammaboards.com has yet too respond and other sites for this are deader then a door nail!

I might need too find replacement parts for the system anyone know where i can find some?
 
make sure you got -5 v some boards neeed -5 to make sound....

also maks sure you dont have a blown speaker or intermitent speaker as that could cause you to blow audio stuff on the boards...
 
If you have static that goes up and down but no game sounds, then it is the -5v. NBA Jam is one of the games that needs -5volts at the jamma connector for the sound to work. I found this out trying to use Yatons 6 in 1 switchers. The -5v was not hooked up and the sound didn't work on some games.
good luck

The problem is'nt the NBA JAM BOARD! It's my 1069 system i'm not getting any sound out of the games.

The little finger board is not responding too anything. But the system boots fine plays fine but theres no sound .
