No signal from the talkback mic or minijack:

Ensure all cables are connected, direct monitoring is on, and instrument is selected. Turn the individual channel knob for the microphone/minijack up until you see the volume meter around it react to sound.

Odd sound in lab from talkback mic/minijack

This is usually a direct monitoring setting issue. Could also be that instrument was not selected. 

No sound from lab

Make sure preamp is on. Sound can also be simultaneously monitored using the headphones of the videomixer as the ceiling mics are coming in on the Line audio channel. Check volume of the control room speakers.
