A 3K9 1/4 watt resistor measures short cct.
Usual question:
Was it the last part de-soldered from the board?
It wasn't just the last, it was the last that could possibly BE desoldered from the faulty node.
I save these little miracles for some future gremlin exploit. Wonder, now, if that day will ever come . . . .

Shorted MLCC (multi-layer ceramic capacitors) are more fun. If overheated, they tend to short circuit. If unevenly heated, they crack and become either an open, short or intermittent circuit. If DC is applied, they become a varactor. If I yell at the PCB, it becomes a microphone.
I don't believe in miracles, but I won't complain when a miracle solves my problem.
In my limited experience, SMD resistors can either become a short or an open circuit, depending on the phase of the moon (waxing or waning).
