Hello,

I have a Gottlieb Wipeout that has a problem on a entire switch strobe.
When i turn on the machine, sometimes the switchs all works regulary.
After 5-10 minutes the switch strobe A stops to work, so the switchs A2 (Left outside R.O), A3 (R. outside R.O.), A4 (Sky-Lift R.O.), A5 (Never ever spot target "L") all don't work anymore.
In the Switch matrixix test menu, there isn't advice of the problem: the switchs appear all good, but if i activate them with finger there is no "feedback" on the display.
I have checked the diode board and the resistor board with multimeter, but resistors and diode on them results all good.
How can i solve the problem on this evil switch strobe A?
I have spent about 20 days for find the prolem, but till now no success. I'm going crazy. :'(
Please, can you help me guys?

Thanks a lot.
