These are all special solenoids that are acting up. Since they work in test consistently and not in game play suggests that the switch ground wire connection is flaky. This ground wire starts at the power supply 3J6 pin 14. So the header pin on the back of the power supply could be cracked. Or the white wire could be coming out of the IDC connector. If both of these are good then it could be a poor connection at the molex connector that connects to the playfield. You didn't say if the upper playfield red flashers work during a game, these are also a special solenoid. If they don't stop working when the other 5 stop, then there is a break in the ground wire under the playfield.

When this happens, tap on the volume pot to see if the sound come back.

F-1 Displays. F-2 Solenoids. F-3 Controlled lamps. F-4 Solenoids. F-5 Input to BR1. F-6 Input to BR1. Flipper power supply fuse for all 3 flippers. Single fuse located by itself lower right of the backbox is for both hide out coils and kickback coil. Single fuse located upper center of the backbox is for the beacon and light.

Most likely you have a shorted transistor which will turn this on any time the power is on. If you have a logic probe I can help you troubleshoot this.
