Had a customer bring in a 1980s arcade cabinet with a weird screen flicker.

It was a Ms. Pac-Man machine from 1982. The guy said, "My kid's birthday is tomorrow, and this was my game as a kid." I spent hours checking the usual stuff, but the issue was a single bad capacitor on the monitor chassis I almost missed. Got it fixed just before closing. Anyone have a good trick for quickly spotting those old, bulging caps before you pull the whole board?

Wait, you found just one bad cap? That's all it took to kill a whole machine?

Have you ever seen a single fuse take out a whole house?

That "single bad capacitor" thing shows how one tiny flaw can bring down a whole system.

But come on, how often does that really happen? I've seen plenty of old electronics with a bulging cap that still kinda work. It's not always a total failure. Sometimes it just makes the screen flicker or the sound buzz. People act like one bad part is an instant brick, but it's usually more of a slow decline.
