The tally sensor should illuminate the talent LED when hit with a flashlight, even before connecting the monitor, to verify the cable and sensor are functional.
The monitor contains active high and active low settings for tally polarity, located in a technical menu rather than the main tally menu.
Power must be supplied to the tally connector on the sled for the system to function properly.
Different rigs may have different power availability on their tally connections, requiring verification on each setup.
When the talent LED does not illuminate with flashlight exposure, the circuit is incomplete somewhere between the sensor and the indicator.

The discussion involves specific equipment from 2014 and may not apply to current models.
The exact location of the active high/low menu setting in the monitor was not definitively specified.
The root cause in this case was incomplete power delivery to one rig's tally connector, which may not apply to all setups.
