YAMAHA RX-V363 - HTR-6130
Starting Self-diagnostic Function
Press the “STANDBY/ON” key while simultaneously pressing STRAIGHT and AUDIO SELECT keys.
Starting Self-diagnostic Function in the protection cancel mode
If the protection function works and causes hindrance to trouble diagnosis, cancel the protection function as described below, and it will be possible to enter the self-diagnostic function mode. (The protection functions other than the excess current detect function will be disabled.)
Press the “STANDBY/ON” key while simultaneously pressing those two keys STRAIGHT and AUDIO SELECT keys . At this time, keep pressing those two keys for 3 seconds or longer.
In this mode, the [SLEEP] segment of the FL display of this unit flashes to indicate that the mode is self-diagnostic function mode with the protection functions disabled.

Canceling Self-diagnostic Function
1. Before canceling self-diagnostic function, execute setting for FACTORY PRESET of main menu No.13 (Memory initialization inhibited or Memory initialized).
# In order to keep the user memory stored, be sure to select PRESET INHIBITED (Memory initialization inhibited).
2. Turn off the power by pressing the “STANDBY/ON” key of this unit.
# Display provided when Self-diagnostic Function started
On the FL display of this unit, an opening message (including the protection history) appears for a few seconds followed by the self-diagnostic function menu display

When there is a history of protection function due to excess current
Cause: An excessive current flowed through the power amplifier.
Supplementary information:
As current of the power amplifier is detected, the abnormal channel can be identified by checking the current detect transistor.
Turning on the power without correcting the abnormality will cause the protection function to work immediately and the power supply will instantly be shut off.

Note:
# Applying the power to this unit without correcting the abnormality can be dangerous and cause additional circuit damage. To avoid this, if “PRI” and “PRD” protection function has been activated 3 times continuously, the power will not turn on even when the “STANDBY/ON” key is pressed. In order to turn on the power again, disconnect the power cable of this unit from the AC outlet once and then reconnect it again.
# The output transistors in each amplifier channel should be checked for damage before applying power to this unit.
# Amplifier current should be monitored by measuring DC voltage across the emitter resistors for each channel.

When there is a history of protection function due to abnormal DC output
Cause: DC output of the power amplifier is abnormal.
Supplementary information:
The protection function worked due to a DC voltage appearing at the speaker terminal. A cause could be a defect in the amplifier.
If the power is turned on with the abnormality unsolved, the protection function works in about 3 seconds to turn off the power.

If the power is turned on with the abnormality unsolved, the protection function works in about 3 seconds to turn off the power.
When there is a history of protection function due to abnormal voltage in the power supply section
Cause: The voltage in the power supply section is abnormal.
Supplementary information:
The protection function worked due to a defect or overload in the power supply.
If the power is turned on with the abnormality unsolved, the protection function works in about 1 second to turn off the power.
Supplementary information:
The protection function worked due to a defect or overload in the power supply.
If the power is turned on with the abnormality unsolved, the protection function works in about 1 second to turn off the power.
When there is a history of protection function due to excessive heat sink temperature
Cause: The temperature of the heat sink is excessive.
Supplementary information:
The protection function worked due to the temperature limit being exceeded. Causes could be poor ventilation or a defect related to the thermal sensor.
Supplementary information:
The protection function worked due to the temperature limit being exceeded. Causes could be poor ventilation or a defect related to the thermal sensor.
If the power is turned on with the abnormality unsolved, the protection function works in about 1 second to turn off the power. For detection of each protection function, refer to main menu described later.
History of protection function
When the protection function has worked, its history is stored in memory with a backup. Even if no abnormality is noted while servicing the unit, an abnormality which has occurred previously can be defined as long as the backup data has been stored. The history of the protection function is cleared when self-diagnostic function is cancelled by selecting PRESET RESERVED (Memory initialized) of main menu No. 13 or when the backup data is erased.
