Hello all,
I'm new to the world of pinball. I just acquired a Space Shuttle that I am trying to get operational.
When I turn it on I don't get any sound. When I do the tests from the back of the coin door still no sound.
when I push the test switch on the cpu board I get sound and the speech callouts. I sent the cpu out for
repair because when the game was switched on it would start in audit mode, the usa in top left was not working
and I could not get the multi ball to release. All of those issues are fixed. I can't seem to figure out my sound issue.
any help is appreciated.

Yes both volume knobs are turned up.
