SERVICE MANUAL

IMPORTANT NOTICE
This manual has been provided for the use of authorized YAMAHA Retailers and their service personnel.
It has been assumed that basic service procedures inherent to the industry, and more specifically YAMAHA
Products, are already known and understood by the users, and have therefore not been restated.

WARNING:

Failure to follow appropriate service and safety procedures when servicing this product
may result in personal injury, destruction of expensive components, and failure of the
product to perform as specified. For these reasons, we advise all YAMAHA product
owners that any service required should be performed by an authorized YAMAHA
Retailer or the appointed service representative.

IMPORTANT: The presentation or sale of this manual to any individual of firm does not constitute
authorization, certification or recognition of any applicable technical capabilities,
or establish a principle-agent relationship of any form.
The data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The research,
engineering, and service departments of YAMAHA are continually striving to improve YAMAHA products.
Modifications are, therefore, inevitable and specifications are subject to change without notice or obligation
to retrofit. Should any discrepancy appear to exist, please contact the distributor's Service Division.

WARNING:

Static discharges can destroy expensive components. Discharge any static electricity
your body may have accumulated by grounding yourself to the ground buss in the unit
(heavy gauge black wires connect to this buss).

IMPORTANT: Turn the unit OFF during disassembly and part replacement. Recheck all work before
you apply power to the unit.

■ TO SERVICE PERSONNEL
1. Critical Components information
Components having special characteristics are marked ! and must
be replaced with parts having specifications equal to those originally
installed.
WALL
2. Leakage Current Measurement (For 120V Model only)
OUTLET
When service has been completed, it is imperative that you verify that
all exposed conductive surfaces are properly insulated from supply
circuits.
Meter impedance should be equivalent to 1500 ohm shunted by 0.15µF.
Leakage current must not exceed 0.5mA.
Be sure to test for leakage with the AC plug in both polarities.

WARNING: CHEMICAL CONTENT NOTICE!
The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where
applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly
other entities) to cause cancer and/or birth defects or other reproductive harm.
DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON
WHATSOEVER!
Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes
to solder/flux vapor!
If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling

● FL display at start-up of diagnostic program
When the diagnostic program has started, the check sum of the main microcomputer or the protection history (*1) is
displayed. If the protection function has been activated in the past, the type and voltage value are
displayed. After a few seconds the diagnosis function menu will appear.
(*1) If a faulty condition is detected such as excessive current, a bad power supply or excessive amplifier DC offset,
the Power will be switched OFF automatically.
Note) For the voltages of the power and DC protection functions, see the diagnosis main menu No. 9, which will be described
later. The protection history will be cleared when "RESERVED" is selected in the diagnosis main menu No. 8
and FACTORY PRESET is engaged.
● Protection history
The following examples show how the protection history is displayed:

CHK S UM : X X X X X

Appears when the protection function has not been activated.
Displayed the check sum (4-digit, hexadecimal) and the version
(one letter) of the main microcomputer.

I P RO T E C T I ON

Appears when the current protection function has been activated.
When power is turned on in an abnormal condition, the power relay
will come on, protection will operate immediately, and power will
turn off.

P S P R T : X X%

For the % value, the voltage at that point is shown by 5V/100%.

(2) Exiting method
The diagnosis function can be exited by any of the following procedures. Take care with the setting of backup memory
initialization menu (diagnosis No. 8) when releasing the diagnosis function.
1. Select sub-menu No. 4 "EXIT" of the diagnosis main menu No. 12.
2. Press the "STANDBY/ON" key on the main unit or "STANDBY" key on the remote control to turn Power OFF.

3. OPERATION AND DISPLAY WHEN STARTING DIAGNOSIS FUNCTION
(1) Selection of diagnostic menu
The diagnostic menu and the sub-menu can be selected by using the front panel keys of the main unit or the remote
control unit.
● Selection by using the front panel keys of the main unit
The main menu can be changed cyclically by using the "PROGRAM / " keys, and the sub-menu, by using the
"PRESET/TUNING / " keys. The " " key will increase the main or sub-menu number.

LARGE: Mode in which speakers with high bass-sound playback capability (large unit) are used. Full-range signals present
on the channel are output from the speaker.
SMALL : Mode in which speakers with low bass-sound playback capability (small unit) are used. Low bass signals (below
90Hz) on the channel are mixed into the channel selected by the LFE/BASS setting.
NONE: Mode in which center speaker is not used. The center channel signal is reduced by 3 dB and mixed into MAIN L/R.
LFE/B:MAIN
: Mode in which subwoofer speaker is not used. The LFE channel signal is reduced by 4.5 dB and mixed into

Caution :

Inhibits initialization of the back-up RAM.
Specify this option protect user set values.

Before setting to the PRESET RESERVED, write down the existing preset memory contents of the Tuner in
a table as shown below. (This is because setting to the PRESET RESERVED will cause the memory contents
to be as factory set, i.e., all the preset memory by the user will be erased.)

IEC958: Standard to identify the PCM bit stream signal. Digital format error refers to a digital signal with the
sampling frequency undefined (neither 32k,44.1k,48k,64k,88.2k nor 96k). Since the operation of each device
cannot be assured at fs outside specifications, this status handled as the forced analog mode (ignored even if
decoding is OK from the detection terminal level), and the signals from the analog input terminal will be
selected. Bits 4-6 of "CPU/1" will be 000B (Analog), and the microcomputer operates in the same way as with

■ AMP ADJUSTMENT
Confirmation of Idling Current of Main Amplifier

• Right after power is turned on, confirm that the voltage across the
terminals of R239(Main Lch),R245(Main Rch), R262(Center),
R252(Rear Lch), R258(Rear Rch) are between 0.1mV and 5.0mV.

• If it exceeds 5.0mV, open (cut off) R213 (Main Lch), R218 (Main
Rch), R233 (Center), R223 (Rear Lch), R228 (Rear Rch) and

•

reconfirm the voltage.
Confirm that the voltage is 0.25mV ~ 15.0mV after 60 minutes.

FM Adjustment
● Before Adjustment

4) Set each switch to the following position unless otherwise

1) For dBµ, 1µV=0dBµ applies.
Example : 60dBµ=1mV
2) 100% modulation means that the frequency deviation is

specified.
