ONKYO TX-NR777 Owner's Manual

|

Problems may be solved by simply turning the power on/

off or disconnecting/connecting the power cord, which 

is easier than working on the connection, setting and 

operating procedure. Try the simple measures on both the 

unit and the connected device. If the problem is that the 

video or audio is not output or the HDMI linked operation 

does not work, disconnecting/connecting the HDMI cable 

may solve it. When reconnecting, be careful not to wind 

the HDMI cable since if wound the HDMI cable may not 

fit well. After reconnecting, turn off and on the unit and the 

connected device.

•  This unit contains a microPC for signal processing 

and control functions. In very rare situations, severe 

interference, noise from an external source, or static 

electricity may cause it to lockup. In the unlikely event 

that this happens, unplug the power cord from the wall 

outlet, wait at least 5 seconds, and then plug it back in.

•  Our company is not responsible for reparations for 

damages (such as CD rental fees) due to unsuccessful 

recordings caused by the unit's malfunction. Before you 

record important data, make sure that the material will 

be recorded correctly.

■ Try restarting the unit

Restarting the unit may help it operate more smoothly. 

To restart the unit, turn it to standby, and then press   

ON/STANDBY on the main unit for at least 5 seconds. 

(The unit's settings will be maintained.) If there is 

no improvement even after the unit is restarted, try 

disconnecting and reconnecting the power cords of the unit 

and connected equipment.

■ Resetting the unit (this resets the unit settings to 

If restarting the unit doesn't fix the problem, resetting the 

unit to the status at the time of shipment may solve the 

problem. If you reset the unit status, your preferences 

will be reset to the defaults. Note them down before the 

operation below.
1.  While pressing the CBL/SAT input selector button on 

the main unit, press  ON/STANDBY.

2.  "Clear" appears on the display and the unit returns to 

standby. Do not unplug the power cord until "Clear" 

disappears from the display.

To reset the remote controller, while holding down MODE, 

press 

 until the remote indicator flashes twice (3 

seconds or more).

■ Cannot turn on the unit

•  Make sure that the power cord is properly plugged into 

the wall outlet.

•  Unplug the power cord from the wall outlet, wait 5 

seconds or more, then plug it in again.

■ The unit turns off unexpectedly

•  The unit automatically switches to standby when the 

"Hardware" - "Power Management" - "Auto Standby" 

setting in the Setup menu functions.

•  The protective circuit function may have been activated. 

If this has occurred, "AMP Diag Mode" appears on the 

display when the unit is turned on again, and the unit 

enters diagnostic mode. If the results of the diagnosis is 

that there is no problem, the "AMP Diag Mode" display 

disappears and you can use the unit normally again. If 

"CHECK SP WIRE" appears on the display, the speaker 

cables may be short-circuited. Make sure bare speaker 

wires are not touching each other or the back panel of 

the unit, then turn the unit on again. If "NG" is displayed, 

immediately unplug the power cord from the wall outlet 

and contact your dealer.

•  The protective circuit function may have been activated 

because the temperature of the unit rose abnormally. 

If this happens, then the power will continue to turn off 

after you have turned the unit on again. Make sure the 

unit has plenty of space for ventilation around it, wait for 

the unit to cool down sufficiently, and then try turning it 

on again.

WARNING: If smoke, smell or abnormal noise is produced 

by the unit, unplug the power cord from the wall outlet 

immediately and contact the dealer or our company's 

support.
