SymptomPossible causeRemedy
The AV Receiver shuts down immediately after being turned on?The amp protection system has been activated.Contact your Onkyo dealer.
There’s no sound coming from the speakers?The AV Receiver is muted and the MUTING indicator is on.Unmeet the AV Receiver (page 39).
The AV Receiver is not connected properly.Make sure that all audio connecting plugs are pushed in all the way. And make sure that the inputs and outputs of all components are connected properly (page 20).
If your turntable doesn’t have a built-in photo preamp, you must connect one between your turntable and the AV Receiver.
If your turntable uses an MC cartridge, you must use a compatible phone preamp.
The speaker cables are not connected properly.Make sure that the polarity of the speaker cables is correct and that the bare wires are in contact with metal part of each speaker terminal (page 17).
The wrong input source is selected.Select the correct input source (page 34).
A pair of headphones are connected.Disconnect the headphones (page 39).
The input signal format is set to PCM or DTS.Set the input signal format to Auto (page 47).
The volume is set at minimum.Turn up the volume (page 34).
The speakers are configured incorrectly.Specify which speakers are connected (page 32), the speaker distances (page 48) and adjust the individual speaker levels (page 49).
The source component is not outputting digital audio.Check the digital audio output setting on the connected device. On some games consoles, such as those that support DVD, the default setting is off.
A compatible digital audio format is not selected on the source component.With some DVD-Video discs, you need to select an audio output format from a menu.
The center speaker is not working or is very quiet?The Stereo, Direct, Pure Audio, or Orchestra listening mode is selected.The center speaker is not used with these modes (page 42).
The level of the center speaker is set at minimum.Check the volume of the center speaker (page 49).

Only the center speaker is working?You’re listening to a mono sound source (e.g., TV or AM broadcast) and the PL II/PL Ix Movie or PL II/PL Ix Music listening mode is selected, so the sound is concentrated in the center speaker.Select another listening mode (page 42).
The surround speakers are not working?Selected listening mode doesn’t use surround speakers.When the Stereo, Direct, or Pure Audio listening mode is selected, the surround speakers produce no sound (page 42).
Surround speaker output depends on the source material, and some material may not use the surround speakers much.

The Surround setting is set to None in the Speaker Configuration.Check the Surround setting in the Speaker Configuration (page 32).
The surround back speakers produce no sound?The level of the surround back speaker is set at minimum.Check the volume of the surround back speaker (page 49).
The Surround Back setting is set to None in the Speaker Configuration.Check the Surround Back setting in the Speaker Configuration (page 32).
The selected listening mode doesn’t use the surround back speakers.Select another listening mode. See page 42 for information on listening modes.
Surround speaker output depends on the source material, and some material may not use the surround speakers much.If you’re playing a Dolby Digital EX or DTS-ES source, make sure that the Dolby Digital/DTS setting is set to On (page 44).
A low-frequency noise or hum can be heard?The audio connecting cables at the rear of the AV Receiver are too close to the power cord.Untangle the audio cables and position them as far away as possible from the power cord.

There’s no picture on the TV?The Pure Audio listening mode is selected.When this mode is selected, the display and the internal video circuits are all turned off and no video signals are output.
The TV’s input selector is set incorrectly.Select the correct input on the TV (i.e., the input to which the AV Receiver is connected).
The video input and output are different formats.The AV Receiver doesn’t convert between video formats. It works as a video signal switcher. Composite video input signals are output only by composite video outputs. S-Video input signals are output only by S-Video outputs. And component video input signals are output only by component video outputs.
The buttons on the AV Receiver work OK but those on the remote controller don’t?The wrong remote controller mode is selected.Select the correct mode (page 10).
The batteries are installed incorrectly.Check the batteries and correct as necessary (page 9).
You’re not pointing the remote controller at the AV Receiver’s remote sensor.Point the remote controller at the AV Receiver’s remote sensor (page 9).
Can’t use the remote controller with other AV components?You’ve connected a MiniDisc recorder or CD recorder to the AV Receiver but haven’t changed the TAPE/MD/CDR display.Press and hold the [TAPE] input selector button until MD or CDR, as appropriate, appears on the display.
The wrong remote control code has been entered.If more than one code is listed, try each one (page 50).
With some AV components, certain buttons may not work as expected and some may not work at all.
You’re pointing the remote controller at the wrong AV component.To control a component connected via ri, point the remote controller at the AV Receiver. To control a component that’s not connected via ri, point the remote controller at that component (page 50)
You’ve made an ri connection but not an analog audio connection (RCA).To use Rl, you must make an Rl connection and an analog audio connection (RCA) between the component and AV Receiver, even if they are connected digitally (page 30).
Reception is noisy, intermittent, and the FM STEREO indicator flashes?You’re too far away from the transmitter. Or, your FM antenna is in the wrong position or pointing in the wrong direction. Or, the station’s signal strength is poor.Use the [TUNING MODE] button to select Manual Tuning mode, and tune the station in mono (page 36).
Adjust the position, height, and direction of your FM antenna.
Install an outdoor FM antenna, preferably one with many elements. Installing an outdoor antenna is a specialist job, so contact your nearest dealer for advice (page 19).
Reception is hindered by a crackling noise?Interference is being caused by fluorescent lights being turned on or off or by passing cars.Install an outdoor antenna as far away as possible from nearby roads.
Adjust the position or direction of your outdoor antenna.
Move your antenna as far away as possible from fluorescent lights.
AM reception is hindered by a buzzing noise, especially at night or with weak signals?Interference caused by electrical equipment, including fluorescent lights.Relocate your AM antenna.

Move the AV Receiver as far away as possible from your TV.
The tuner presets no longer work?The power cord has not been connected to a wall outlet, or the power has been turned off for an extended period.Preset your favorite radio stations again (page 37). The power cord must be plugged into a wall outlet a few times each month in order to preserve the presets.
Sound can be heard from the speakers, but it cannot be recorded?From the VIDEO 1 OUT, you’re trying to record the signal being fed into the VIDEO 1 IN, or from the TAPE OUT, you’re trying to record the signal being fed into the TAPE IN.To prevent signal loops and damage to the AV Receiver, input signals are not fed through to outputs with the same name (e.g., TAPE IN/OUT or VIDEO 1 IN/OUT).
You’re playing Dolby Digital or DTS source material. You cannot record from an AV component that is connected digitally.Although you cannot record Dolby Digital or DTS surround channels, you can record the left and right channels by connecting the source AV component’s analog left and right outputs to a pair of analog inputs on the AV Receiver.
The wrong input source is selected on your recorder.Select the correct input source. See your recorder’s manual for more information.
