One way of finding out if an RC is actually transmitting a signal is to
hold it close to a radio with a ferrite rod aerial, and tuned to a quiet
spot on the long wave. If the RC is transmitting, you will hear a
'burpity-burp' noise when you press the a button.

How does that detect a failure of an infrared transmitter?
