An old trick with audio RCA inputs is to hold an input cable by the shield with your thumb and third finger, then lightly touch the center pin with your index finger. Because your hand is grounded, the signal should be just a moderate amount of hum, but enough to tell if an amplifier circuit is working or dead.
