TX-8270 - Troubleshooting: Power

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 isn't fixed after referring to "Troubleshooting", resetting the unit to the status at the time of shipment may solve the problem. Note that your settings will also be initialized when you reset, so we recommend that you note down your settings before doing the following. 

• 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. 
• We are 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 

The issue may be fixed by restarting this unit. After switching this unit to standby, press and hold Í ON/ STANDBY on this unit for 5 or more seconds to restart the unit. (The settings in the unit are maintained.) If the issue is not fixed by restarting, try unplugging the power cords of the unit and connected devices, and then plugging them in again. 

Resetting the unit (this resets the unit settings to the default) 

If restarting the unit doesn't fix the problem, resetting the unit to the status at the time of shipment may solve the problem. Your settings will also be initialized when you reset, so note down your settings before doing the following. 

1. While holding down TUNING MODE on the main unit, press ON/STANDBY. 
2. 2. The unit switches to standby and the settings are reset.

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 "3.
  Hardware" - "Auto Stby" 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 customer support.
