Yamaha produces A/V receivers for budget, mid-range and luxury stereo systems. All Yamaha receivers can produce 5.1 channel surround sound. Yamaha receivers can break down for a number of reasons. Most issues, however, can be identified and resolved by the user. Fixing the receivers yourself saves both time and money.

Skill level:


  1. 1

    Examine all cable connections moving into and out of the receiver. Look for any signs of wear on the cable ends. Scratches, dents or rust can all stop sound output. Replace any damaged cables and try playing audio through the speaker system.

  2. 2

    Look for loose wiring on the inside of the unit. Open up the back panel of the receiver with a screwdriver. Use a flashlight to examine the wiring inside. Any frayed or loose wiring can prevent sound output. You will need to replace any damaged wiring.

  3. 3

    Switch between audio modes on the receiver. Yamaha receivers have an S-Video, Component 1, Component 2, Component 3, DVD and CD modes. These audio modes all sit in the front of the receiver. Turn on the receiver and turn up the master volume knob. Listen for sound output out of each of them. You may have incorrectly wired the receiver if you did not hear audio from one mode. Refer to the Yamaha receiver owner's manual for wiring instructions.

  1. 1

    Turn off the Yamaha receiver and let it cool for several minutes. Yamaha receivers have a built-in electrical protection circuit. This circuit will automatically shut off the receiver if it detects a threat to the main circuit, like overheating or a power surge.

  2. 2

    Clean off the air vents in the back of the Yamaha receiver. The receiver collects dust and dirt over time. This dust can trap heat inside the unit and trigger the circuit protection system.

  3. 3

    Turn on the receiver and turn up the master volume knob. Play audio through the receiver and listen to the results. Repeat Steps 1 and 2 if the sound cuts out again.
