My WCS started having what I've now learned is a very common reset problem (booted up, starts, first touch of a flipper resets the game).
I bought a soldering iron, watched enough youtube videos to figure it out and got to work. I am developing only the vaguest understanding of how all this crap works by the best way I know how - breaking things, then figuring it out.
So I replaced the two bridge rectifiers and the four capacitors around it. Didn't work (same reset issue as before). Then I replaced the little C4 capacitor (spec'd in the manual as 100mfd 10v) with a 100mfd 16v and it worked... but reset randomly halfway into the tenth game. This pissed me off a lot after what felt like an epic personal victory.
After rewatching a series of excellent videos on pinballhelp.com, I replaced that C4 again with a 470mfd 25v (per instructions). Now it resets before even getting out of the test screen.
And now my question: have I screwed it up worse? Should I just go back to the original C4?
I've begun to really enjoy the soldering. Not so much with the desoldering.
