Q:

'True bypass' pedal doesn't allow signal to pass through when turned off

I've never really messed with guitar pedals so I'm a little confused. I just got the Hall of Fame Reverb pedal of TC and it says true bypass on it. When the pedal is off, I don't hear anything from the amp. Does this mean if that pedals is gonna be in line with others, it has to be on the whole time? 

A:

There must be something wrong with the pedal. The indication 'true bypass' means that when the pedal is connected with the guitar and amp and is turned off, the signal will pass directly to the amp.

With a true bypass pedal, when the pedal is in bypass mode (off), the guitar signal is routed directly to the guitar amplifier without any of the interference, loading, or buffering effects that are often caused by the pedals that are in-between.

If you have it turned off, you should hear your guitar cleanly. If you do not, there must be something wrong with the pedal.
Just make sure that everything else works correctly:

The cables
The guitar
The amp
The pedal (when it's turned on)
If you have multiple pedals, make sure all of the cables are connected correctly and are all the way in.

If all of these work correctly, then something in the pedal is not working as it should. Take it to a technician or to the store if it has warranty.
