Hey all, long time browser first time poster.
I have recently purchased a WWH2O. I knew it had battery damage when I bought it so iv replaced the CPU board with a brand new board from pinball basement and also installed a color led dmd. Other than that its all original and shoots great only problem is it will randomly crash and crash hard! Everything goes black when this happens and the speakers pop (scarribg the living out of me most times) Good news is if you turn the power off for 15sec and back on it comes back to life good as new. I should note it will do this while playing it and also while its just sitting there turned on, has never blown a fuse and while playing it I can hold both flippers down for as long as I want and this doesn't seem to crash it (I read a thread that can be a common prob ♂️) Iv stopped playing it in fear that one of these times its just not gonna come back and its so random I have no idea where to start troubleshooting. Any help would be greatly appreciated.
