I have a Gottlieb System 3 Cactus Jack's that plays no music, sound effects, or voices. The sound board and aux sound board both have flashing LEDs. There is no double squelch when the game is powered on. My voltages all test good. Fuses all test fine. The only other issue with the game is that the solenoid test does not work, but the solenoids function properly during gameplay. The sound test does not work. Pressing the reset switch, SW2, on the sound board does not appear to do anything.

Before I start replacing chips and boards, I wanted to see if anyone had any tests or less intrusive options to try. Thanks!
