7: Additional information Troubleshooting Incorrect operations are often mistaken for trouble and malfunctions. If you think that there is something wrong with this component, check the points below. Take a look at the other components and electrical appliances being used, because sometimes the problem may lie there. If the trouble isn't sorted out even after going through the checks below, ask your nearest Onkyo authorized independent service company to carry out repair work. • If the unit does not operate normally due to external effects such as static electricity disconnect the power plug from the outlet and insert again to return to normal operating conditions. General  The power does not turn on. # Disconnect the power plug from the outlet, and insert again.  The receiver suddenly switches off. # When the Auto Power Down function is working, the power will automatically turn off if the receiver has not operated for several hours. Check the setting for the Auto Power Down function (see The Auto Power Down menu on page 29). # Make sure there are no loose strands of speaker wire touching the rear panel. This could cause the receiver to shut off automatically. # After about a minute (you won't be able to switch the unit on during this time), switch the receiver back on. If the message persists, call a Onkyo authorized independent service company. # If there is very little low frequency information in the source material, change your speaker settings to Front: SMALL / Subwoofer: YES, or Front: LARGE / Subwoofer: PLUS (page 27).  The input of this unit switches from one to another. (When the ARC function is ON) # The CEC (Consumer Electronic Control) function may activate when the ARC function is turned ON, causing the input to switch from one to another. Since this unit does not guarantee synchronized operation based on the CEC function, turn OFF the HDMI CONTROL setting on the connected player. Refer to the relevant device's instruction manual for details. If this does not work, turn OFF the ARC function. If this is the case, listen to the TV audio after connecting this unit and the TV with an audio cable.  OVERHEAT shows in the display and the power turns off. # The temperature within the unit has exceeded the allowable value. Try moving the unit for better ventilation. # Lower the volume level.  TEMP shows in the display and the volume level drops. # The temperature within the unit has exceeded the allowable value. Try moving the unit for better ventilation. # Lower the volume level.  No sound is output when an input function is selected. # Use VOL +/- to turn up the volume. # Press on the remote control to turn muting off. # Set the AUDIO SEL to H (HDMI), C1/O1 (digital) or A (analog) according to the type of connections made (page 18). # Make sure the component is connected correctly (see Connecting your equipment on page 8). # Check the audio output settings of the source component. # Refer to the instruction manual supplied with the source component.  No image is output when an input function is selected. # Make sure the component is connected correctly (see Connecting your equipment on page 8). # Use the same type of video cables for the source component and TV to connect to this receiver (see About video outputs connection on page 11). # The video input selected on the TV monitor is incorrect. Refer to the instruction manual supplied with the TV.  No sound from subwoofer. # Make sure the subwoofer is switched on. # If the subwoofer has a volume knob, make sure it's turned up. # The Dolby Digital or DTS source you are listening to may not have an LFE channel. # Switch the subwoofer setting in Speaker Setting on page 27 to YES or PLUS.  No sound from surround or center speakers. # Connect the speakers properly (page 9). # Refer to Speaker Setting on page 27 to check the speaker settings. # Refer to Channel Level on page 28 to check the speaker levels.  No sound from a specific speaker. # Make sure the speaker cable is connected correctly. (Ensure that the connection terminal is correct, that the speaker wire is firmly inserted, and that no speaker wire is touching the rear panel.)  Considerable noise in radio broadcasts. # Connect the antenna (page 14) and adjust the position for best reception. # Route any loose cables away from the antenna terminals and wires. # Fully extend the FM wire antenna, position for best reception, and secure to a wall (or connect an outdoor FM antenna). # Connect an additional internal or external AM antenna (page 14). # Turn off equipment causing interference or move it away from the receiver (or move antennas farther away from equipment causing noise).  Broadcast stations cannot be selected automatically. # Connect an outdoor antenna (page 14).  Noise during playback of a cassette deck. # Move the cassette deck away from your receiver, until the noise disappears.  No sound is output or a noise is output when software with DTS is played back. # Make sure the player's settings are correct and/or the DTS signal out is on. Refer to the instruction manual supplied with the DVD player.  There seems to be a time lag between the speakers and the output of the subwoofer. # See Automatically setting up for surround sound (AccuEQ Room Calibration) on page 16 to set up your system again using AccuEQ Room Cal. (this will automatically compensate for a delay in the subwoofer output).  After using the AccuEQ Room Cal. setup, the speaker size setting (LARGE or SMALL) is incorrect. # Low-frequency noise could have been caused by an air conditioner or motor. Switch off all appliances in the room and rerun the AccuEQ Room Cal. setup.  Can't operate the remote control. # Replace the batteries (page 7). # Operate within 7 m (23 ft.), 30º of the remote sensor (page 7). # Remove the obstacle or operate from another position. # Avoid exposing the remote sensor on the front panel to direct light. 2 4 31 31
