Title: Williams Flash Problems
Post by: Pinballrocks on July 30, 2021, 08:46:31 PM

 Hi all,
I have just had my Williams flash CPU boards repaired and they are all good now.
The machine boots up and i press the start button all is good as soon as I activate any of the flippers they drop and I lose all power.
I turn the machine off and restart and the same thing happens.


Any Ideas on where to look for the problem would be greatly appreciated???


Thanks Paul.

Check the 5 volts on the CPu make sure it’s 5v if that’s ok check the diodes on the flipper coils
