TIL a dead capacitor can look perfectly fine

Spent 3 hours chasing a no-power issue on a Samsung TV last Wednesday, checked every fuse and voltage rail twice. Finally pulled the power board and tested a capacitor that looked brand new no bulging or leaking, but it read 0 capacitance on my meter. Anyone else ever get burned by a component that looked good but was totally dead?

Honestly, found a dead resistor looking totally fine once, drove me nuts for days.

Yeah, those hidden failures are the worst... multimeter saved my sanity there.

Multimeter's the first thing I grab now. Saves pulling half the board apart for nothing.
