i found two ways:
[Restarting Pioneer receiver]
To restart the unit, turn it to standby, and then press [STANDBY/ON] 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 Pioneer receiver]
1. While holding down [AUTO/DIRECT] on the main unit, press [STANDBY/ON] on the main unit.
2. "Clear" appears on the display and the unit returns to standby. Do not unplug the power cord until "Clear" disappears from the display.

i tried only reset
