Hi Bailey,
Before you bail out and head for the repair depot first try connecting some headphones to the Receiver, select Phono, switching on the Main Zone - On/Off (Button K on page 4 of the manual) and slowly turn up the volume while playing a record. If you hear music, you'r part way there. If you don't hear anything, connect an AM or FM antenna and try it as the source.
With minimal or even no output, on the Speakers Connected Indicator on the front display (bottom right corner of the display - see page 5) you should see L & R connected if those are the only two speakers connected correctly on the rear of the receiver. (See page 5 for speaker connections.)
Note the "negative" for each speaker goes to the corresponding negative post which is on the bottom row. The "positive" in each pair goes to the corresponding upper post. Check both ends of the speaker cables for good connection. I don't know how many times folks have connected both wires from a speaker to the positive posts for a speaker pair on the back of a receiver, and connected the negative posts to the other speaker output pair, and say the Receiver is faulty.
I hope this is helpful.
