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
AC LEAKAGE
installed. WALL EQUIPMENT TESTER OR
2. Leakage Current Measurement (For 120V Model only). OUTLET UNDER TEST EQUIVALENT
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.
INSULATING
• Be sure to test for leakage with the AC plug in both polarities. TABLE

 RX-V495/RX-V495RDS/HTR-5140/HTR-5140RDS

FL display at start-up of diagnostic program

When the diagnostic program has started, the history (*2) of the protection function (*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.

(*2) The protection records will be cleared when "RESERVED" is selected in diagnosis menu No. 8 and FACTORY
PRESET is engaged.

History of protection function

Each case of the history of the protection function is displayed as shown below.

Appears when the protection function has not been activated.

1 DVD/LD NO PROTECT

Appears when the current protection function has been activated.

1 DVD/LD I PROTECT When power is turned on in an abnormal status, the power relay
will come on, protection will operate immediately, and power will
turn off.

Appears when the power protection function has been activated.

1 DVD/LD PS : 21% For the % value, the voltage at that point is shown by 5V/100%.
When power is turned on in an abnormal status, power will turn off
after half a second.

Appears when the power amp DC protection function has been

1 DVD/LD DC : 19% activated.
For the % value, the voltage at that point is shown by 5V/100%.
When power is turned on in an abnormal status, power will turn off
after two seconds.

(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 diagnosis menu No. 11/submenu No. 6 "EXIT".
2. Press the "STANDBY/ON" key on the main unit or "STANDBY" key on the remote control to turn power off.

4. CONTENTS OF DIAGNOSIS FUNCTION

This section describes the contents of the self diagnosis function in detail.

No.1 ANALOG THROUGH

The input is fixed to analog (A/D). There are two submenus.

1. MAIN BYPASS 1 DVD/LD MAIN BYPAS

The MAIN L/R signals bypass the analog circuits to be output.
For CENTER/SUBWOOFER, FRONT L/R and REAR L/R, the MAIN L/R signals via the DSP are output without
being processed (through). (Remote control code 7A-88)

The input is automatically discriminated by signal detection and switched with priorities AC3>PCM
Audio>analog. There are the following three submenus.

1. YSS908-SRAM 2 DVD/LD YSS908SRAM

MAIN L/R are input to the DSP via AC3Dav, pass through SRAM, and are then output to all channels without
being processed. (Remote control code 7A-89)

[Note]
IEC958: Standard to identify the PCM bit stream signal. Digital format error refers to a digital signal with the
sampling frequency undefined (neither 44.1k, 32k nor 48k). Since the operation of each device cannot be
assured at fs outside specifications, the sub-microprocessor handles this status as the forced analog mode
(ignored even if decoding is OK from the detection terminal level), and selects the signal from the analog input
terminal. Since the sub-microprocessor transmits 000B (analog) for STATUS#0 bits 4-6 to the main
microprocessor, the main microprocessor visually operates in the same way as with digital unlocking.
