3. Lubricants, Glues, and Replacement parts

A

4. Cleaning

1 Use specified parts for repair.

Use genuine parts. Be sure to use important parts for safety.

2 Do not perform modifications without proper instructions.

Please follow the specified safety methods when modification(addition/change of parts) is required due to interferences such as radio/TV interference and foreign noise.

3 Make sure the soldering of repaired locations is properly performed.

When you solder while repairing, please be sure that there are no cold solder and other debris.

Soldering should be finished with the proper quantity.

4 Make sure the screws are tightly fastened.

Please be sure that all screws are fastened, and that there are no loose screws.

5 Make sure each connectors are correctly inserted.

Please be sure that all connectors are inserted, and that there are no imperfect insertion.

6 Make sure the wiring cables are set to their original state.

Please replace the wiring and cables to the original state after repairs.

In addition, be sure that there are no pinched wires, etc.

7 Make sure screws and soldering scraps do not remain inside the product.

Please check that neither solder debris nor screws remain inside the product.

8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord.

Damaged power cords may lead to fire accidents, so please be sure that there are no damages.

If you find a damaged power cord, please exchange it with a suitable one.

9 There should be no spark traces or similar marks on the power plug.

When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure connections and suitable usage.

Please exchange the power cord if necessary.

10 Safe environment should be secured during servicing.

When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries.

Please pay attention to your surroundings and repair safely.

To keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification.

Adjustments should be performed in accordance with the procedures/instructions described in this manual.

Also, No Adjustments should be performed in accordance without the procedures/instructions described in this manual, such as the tuner pack.

Service Notes

D

Components identified by mark on the schematic diagram and by mark “!” in the parts list are critical for risk of fire and electrical

D

shock. Replace these components with ONKYO parts whose part numbers appear as shown in this manual.

2. Safety check after servicing

(1) To ensure safety, check that the covered insulating sheet or tube are removed, all parts and wires which are removed or

disconnected while servicing have been put back to their original positions after servicing.

(2) To insure structural integrity, check that all the screws or mechanical parts have been put back in their original positions after

servicing.
(3) Check that in the process of servicing or replacing parts that the surrounding area has not been contaminated or adversely affected.
(4) After servicing an insulation check on the external metal connectors and between the blades of the power plug must be performed.

C

Method of checking insulation resistance

C

Unplug the power cord and short the both ends of the plug with a jumper wire.
Using a 500V insulation resistance tester, check that the insulation resistance value between the plug of the power cord

and externally exposed metal parts is 1MΩ or greater.

※The mechanical power switch should be turned on if it is available.

3. Caution on replacing the battery

Danger of explosion if rechargeable batteries is incorrectly replaced. Replace only with the same or equivalent type recommended by the
manufacturer. When disposing of used batteries, please comply with governmental regulations or environmental public institution’s rules
that apply in your country / area.

B

4. Other Cautions

B

・When AC plug is non-polarized and if Main or Primary fuse enters in the Neutral line of AC Mains supply or if there is possibility of Main

or Primary Fuse entering in the Neutral line of AC Mains supply, then AC Mains supply must be disconnected to de-energize the circuit.

・Be sure to use only lead free solder.

・When soldering, please be careful not to use too much solder and affect adjacent components.

・When you repair the CD Player, Please do not stare into the beam in Optical Instruments and do not view directly since there is visible

and invisible laser radiation when open the unit.

Diagnostic Function

This function is for avoiding the rupture of electrolytic capacitors with amplifier circuit failure during
power-ON.

Operation of Self-diagnostic

D

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(SEC1­LOW), 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

C

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.

B

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.

Firmware Update

[Preparation of Update]

1. Connect the USB storage device to your PC . If there is any data in the USB storage
device, remove it.

2. Download the firmware file (package file) from the OPSIS-server.

However European serv ice partner s should download the firmware file (package file)
from the ExtraNet.

ID and Password are those we informed when changed.
Filename is as follows: ONKAVR002B_Rxxx_xxx.zip for TX-SR393, HT-R398
Filename is as follows: ONKAVR002C_Rxxx_xxx.zip for TX-SR494, HT-R495
Filename is as follows: ONKAVR002B_Rxxx.zip for TX-SR292BT

Unzip the downloaded file. A following file is created.

AVR002B**************.of1 for TX-SR393, HT-R398
AVR002C**************.of1 for TX-SR494
AVR002B**************.of1 for TX-SR292BT

There is one file for update.

3. Copy it to the USB storage device. Be careful not to copy the zip file.

4. Remove the USB storage device from your PC.

How to Check Idling Current

a. Aging

D

The AVR is turned on about 6 minutes for aging.

b. Idling After-check

Channel FL,FR,C,SL,SR,SBL,SBR

Terminals P6021,P6022,P6023,P6025,P6026,P6027,P6028

*Connect 1/4W 100 ohms resisters in each probe of multi mater .

C

*If the measured value are under 1 mV or over 10 mV, you have to make sure repair.

When there is no measured connector on the board:

1. Measure by inserting a like thin pin into the hole of the connector for measurement.

2. Measure via connector as shown.
