When the auto power standby function is enabled, the unit
automatically turns off in any of the following situations:
- No operations have been performed for 8 hours
- HDMI 1–2, BLUETOOTH, or NET is selected as the input source, but
no audio has been input to the unit or no operations have been
performed with the unit for more than 20 minutes.
Turn on the unit again. If the auto power standby function is not used, disable
the function (p. 50).
The protection circuitry has been activated. (The STATUS indicator on
the center unit flashes.)
After confirming that all connections are made properly, turn on the unit again.
If the power still turns off frequently, unplug the power cable from the AC wall
outlet and contact the nearest authorized Yamaha dealer or service center.
The power cannot be turned on.
The protection circuitry has been activated three times consecutively.
(If you try to turn on the power in this condition, the STATUS indicator
on the center unit will flash.)
To protect the product, the power cannot be turned on. Unplug the power
cable from the AC wall outlet and contact the nearest authorized Yamaha
dealer or service center.
All indicators go out although the unit is
turned on (it may seem that the unit is turned
off).
The unit is configured so that indicators do not glow or flash unless the
unit is being operated.
Select the desired brightness from “Dimmer” in the setup menu (p. 49).
The unit does not function correctly.
The internal microcomputer is frozen, due to an external electric shock
(such as lightning or excessive static electricity) or to a drop in the

unit. (If the problem persists, unplug the power cable from the AC wall outlet
and plug it again.)
