BenMalone08, a couple of pieces of information will help:
1. What make/model is the TV that you are referring to?
2. When you say "monitor out", is this a yellow colored jack, a coaxial/digital jack, or a white and a red colored jack? Are there any other jacks labeled "Audio Out" not being used?
3. Where are the connections from your TV going to on the receiver? Are they labeled "Audio In" or "Monitor In"?
4. Are you trying send a 5.1 audio signal or just stereo (2 speakers) signal to your receiver?
5. Not trying to be rude - Is your receiver set to the right input? My parents have done this before...
Hope we can help.
