Cue Ball Wizard
Gottlieb, 1992I have a System 3 gottlieb Cue ball wizard with an issue regarding the Strobe row 411.The 8 switches on the row work in switch test mode and all solenoids fire as well in solenoid test.I have checked for continuaty from the driver board to the diode board and all is ok.But in game play all switches are not registering to fire the solenoids and the pop bumper lamps on the 411 strobe are not working.Any help would be great.
Strobes are shared between the switches and lamps in Sys3 games. What this means is that if you have a problem with the lamp matrix (short/bad wiring/bad diode/bad LED), switches will not work properly during the game.
The problem is that in test mode, the lamp matrix is not active so it is possible that all switches test out properly in switch test but then don't function properly in game play.
To diagnose this issue, you must run the individual lamp test and check for any sort of ghosting in lamps other than the one in test. If you have it, you have to chase down the lamp problem and correct it. If you don't you will have problems with switches registering in game.

Just a follow up.After not having any luck tracking down a shorted bulb socket i pulled the driver board out and sent it away for testing.The board checked out ok on the bench test using a gottlieb diagnostic machine.The guy who did the board repair also has a cue ball wizard.It showed the same issue when he installed it in his cbw.Turns out it was bad transistor for strobe 411 after all which tested fine but was faulty no less.
