Others Troubleshooting First check the followings. Since the issue may be caused by other components that are connected, be sure to also check them while referring to their manuals. Further product operating procedures and FAQs (frequently asked questions) are available from the Onkyo web site. Tip Before requesting repairs If the integrated amplifier is no longer working or functioning, any issues may be resolved by resetting the microcomputer contained in the integrated amplifier to revert all settings to their defaults. Before requesting repairs, follow the procedure below to reset the microcomputer. With the integrated amplifier turned on, hold down DIRECT and press ÍON/STANDBY. Power Can't turn on the Integrated Amplifier. • Make sure that the power cord is properly plugged into the wall outlet (Ä page 20). • Unplug the power cord from the wall outlet, wait 5 seconds or more, then plug it in again. The Integrated Amplifier turns off unexpectedly. • When the protection circuit is activated (because of speaker short-circuit, overload, or over-current), the integrated amplifier enters Standby mode. Remove the source of the problem and turn the integrated amplifier back on. • Check that the switch on the back of the integrated amplifier is set to the correct setting (Ä page 25). • The settings are not enabled when the switch is changed during the Standby mode. To change a setting, be sure to turn on the unit prior to making any changes. • If this unit is being used as a power amplifier and input is switched to "MAIN IN", then if the volume of the connected pre-amplifier is low, auto standby (Ä page 25) may function and the power may automatically switch to standby. If this happens, you may be able to fix it by increasing the volume on the pre-amplifier. En 28 Audio There's no sound. • Make sure the integrated amplifier's volume control is not set to minimum (Ä page 22). • Make sure the correct input source is selected (Ä page 23). • Make sure the integrated amplifier is not muted (Ä page 24). • Make sure the speakers are connected correctly (Ä page 12). • Check all connections and correct as necessary (Ä page 12). • While headphones are connected, the speakers output no sound (Ä page 24). • The integrated amplifier does not support digital formats other than PCM. Inputting a digital format other than PCM will cause loud noise. The sound quality is not good. • Make sure the speaker cables are connected with the correct polarity (Ä page 12). • Make sure all audio connecting plugs are pushed in all the way (Ä page 14). • The sound quality can be affected by strong magnetic fields, such as those from a TV. Try moving any such devices away from the integrated amplifier. • If you have any devices that emit high-intensity radio waves near the integrated amplifier, such as a cellular phone that's being used to make a call, the integrated amplifier may output noise. Headphone output is intermittent or there's no sound. • This may be due to dirty contacts. Clean the headphones plug. See your headphones' instruction manual for cleaning information. Also, make sure that the headphones cable is not broken or damaged. Audio performance • Audio performance will be at its best about 10 to 30 minutes after the integrated amplifier has been turned on and had time to warm up. • Using cable ties to bundle audio cables with speaker or power cables may degrade the sound quality, so refrain from doing it. • Depending on the country, the integrated amplifier may be polarity-sensitive. In this case, plug the power cord in a way that provides the best sound quality. • Install the integrated amplifier on a sturdy rack or shelf. Position it so that its weight is evenly dispersed on its four legs. Do not install the integrated amplifier in a place with vibration or an unstable location. • Plug the power cord into an AC wall outlet.
