SAFETY-RELATED COMPONENT WARNING!! :
COMPONENTS IDENTIFIED BY MARK ON THE SCHEMATIC DIAGRAM AND IN THE PARTS LIST ARE CRITICAL FOR RISK OF FIRE
AND ELECTRIC SHOCK. REPLACE THESE COMPONENTS WITH ONKYO PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN
THIS MANUAL. MAKE LEAKAGE-CURRENT OR RESISTANCE MESUREMENTS TO DETERMINE THAT EXPOSED PARTS ARE
ACCEPTABLY INSULATED FROM THE SUPPLY CIRCUIT BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER.
This service manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer. Qualified technicians have the

Self-diagnostics
This function is for avoiding the rupture of electrolytic capacitors with amplifier circuit
failure during power-ON.
Operation of Self-diagnostic
Self-diagnostic will start at the timing of next power on, after goes to the protect mode
by Current detection or DC voltage detection.
Only On/Standby key could work in this mode. Also remote control does not work.
However, the CLEAR operation is enabled.
During Self-diagnostic, the power supply for amplifier circuit become low voltage
state(SEC1-LOW), and the speaker relay will be turned off. Then, MPU will check each
amplifier circuits Internally by entering the test signal (20 kHz,-20 dBFS sine wave) to
each channel from DSP.
MPU will judge the amplifier circuit is good or not from VOLH value.
The normal range of VOLH value is 0.04 V < VOLH < 0.20 V.
If VOLH value is in the out of this range, it will be judged as NG (No good).
No problem found
When protected by current detection, and no problem found, "CHECK SP WIRE“ will be displayed.
In this State, Only the On/Standby key is effective. And if do not anything for 3 minutes, unit goes
into standby automatically.
When protected by a DC voltage detection, and no problem found, unit goes into normal
operation.
Problem found
When judged as there is a problem on any channel, the information of channel that has a problem
will be displayed as in the right figure.
In this State, Only the On/Standby key is effective. Also remote control does not work. If do not
anything for 3 minutes, unit goes into standby automatically. This state will keep also after unit
turn on/off, or AC unplugged.
the power supply for amplifier circuit become low voltage state(SEC1-LOW), and the speaker
relay will be turned off.

Repair Process and How to Confirm
Confirmation of the protect cause
While NG channel is displayed, You can confirm the protect cause by following the step below.
1. Press the Enter button
2. The protect cause are displayed for 5 seconds.
Please check the around of those amplifier circuit and repair it.
Clear of NG CH information
After repair, you can clear NG CH information by following the steps below.
1. Press the On/Standby key while pressing the Enter key.
2. Display as in the right figure appears.
3. Unit goes into Standby automatically after 5 seconds.
Self-diagnostic will start again at the timing of next power on.
By this, You can verify whether repair was properly or not.
If problem found after repair, please re-check the around of its circuit.
Cancel of Self-diagnostic
You can cancel this mode by clear operation (press Standby key while pressing CBL/SAT key).
After cancel this mode, receiver will be started as normal operation.

IMPORTANT!!
Back Ground:
It is totally different from Radio Law at the each country on 5GHz band.
It means it is totally different from enabled Channel of 5GHz band at the each country.
We define the “Country Code” for 5GHz band.
You must set up the appropriate country code to the product.
Example;
Case1:
When you use the “P” destination products and bring move to Russia or Israel,
If you did not setup change country code and use in Russia and Israel,
You will be on the illegal Radio Law in Russia and Israel.
Case2;
When you use “C” or “D” destination product bring move to Japan or Taiwan,
If you did not setup change country code and use in Japan and Taiwan,
You will be on the illegal Radio Law in Japan and Taiwan.
Service Parts information:
The default country code is set on “Processing Circuit Board(PRC board)”.
You must make sure and set up the “Country Code“ when you replace the processing
circuit pc board.
Otherwise You and your customer should be on the illegal Radio Law and
IT HAS POSSIBILITY TO HAVE A RISK OF
PUNISHMENT FROM EACH COUNTRY GOVERNMENT.
If you did not make sure country code and no setup code and face any trouble,
We does not have any responsibility.
For setting up the Country Code,
Please ask the procedure of changing country code
to your distributer or our sales.
It is no described the procedure of changing Country Code on this Service Manual
If you have any trouble of unclear procedure for update country code,
Please contact our sales department.
PRC Board Default Value of Country Code
The PRC board is already set default Country Code by the representative destination.
To confirm the default country code, Please refer to the "How to read PRC Board part
number and Default value of Country Code"section.

Make sure and Setup Country Code
You have to make sure country code for using or replacing “Processing Circuit PC
Board”.
It means that you have to make sure country code between using Processing Circuit
PC board( PRC Board) and your customer’s country code.
When it is not match PRC board default country code and customer’s country, you
have to setup Country Code.
Case3;
When you repair the “P” destination products and replace “P” destination PRC Board
and the customer live in UK, It is no necessary to setup Country Code
Because “P” destination PRC board already setup “EU” country code.

NO NECESSARY TO SETUP COUNTRY CODE
Case4;
When you repair the “P” destination products and replace “P” destination PRC board
and the customer live in Russia, It is necessary to setup Country Code
Because “P” destination PRC Board already setup “EU” country code.
However, the customer’s country code is “RU”. It means no match PRC Board code
and Customer’s code.

Case6;
When you repair the “C” destination product and replace “C” destination PRC board
and the customer live in Taiwan, It is necessary to setup Country Code.
Because “C” destination PRC Board already setup “US” country code as default.
However, the customer’s country code is “TW”. It means no match PRC Board code
