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.

2. BEGINNING AND CANCELLATION
(1) Starting up the function and the display
After starting up, main-menu No.1 is selected.


A. How to start diagnostic program
Using the front panel keys of the main unit.
Plug in the AC power cord. With the Power OFF, hold down the "PRESET/TUNING " and "A/B/C/D/E" keys
simultaneously (Step 1), then press the "STANDBY/ON" key (Step 2).
Sub menu No. 1 of the diagnosis main menu No. 1 will start.

FRONT PANEL
"STANDBY/ON" key "A/B/C/D/E" key "PRESET/TUNING " key




Step2. Press the "STANDBY/ON" key. Step1. Hold down the "PRESET/TUNING "
and "A/B/C/D/E" key simultaneously.



B. Settings for start-up of diagnostic program
The settings used when starting the diagnostic program are as follows.
1. EFFECT LEVEL :
CHANNEL CENTER R SUR L SUR SWFR
LEVEL (dB) 0 0 0 0

2. MUTING : OFF
3. INPUT (VIDEO) : DVD/LD (DVD/LD)
4. CENTER SPEAKER : LARGE
5. REAR SPEAKER : LARGE
6. MAIN SPEAKER : LARGE
7. LFE/BASS OUT : SWFR




C. Start-up display
The protection history information appears on the front panel display.




9
RX-V596/HTR-5250/RX-V596RDS



q 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.

q Protection history
The following examples show how the protection history is displayed:


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



Appears when the current protection function has been activated.
I P RO T E C T I ON 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% Appears when the power supply protection function has been
activated.
For the % value, the voltage at that point is shown by 5V/100%.
When power is turned on in an abnormal condition, power will turn
off after half a second.

Appears when the power amp DC protection function has been
D C P R T : X X% activated.
For the % value, the voltage at that point is shown by 5V/100%.
When power is turned on in an abnormal condition, 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 sub-menu No. 3 "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.
q 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.

No.2 DSP THROUGH
The input is automatically discriminated by signal detection and switched with priorities Coaxial>Optical>Analog.
There are the following three sub-menus.


1. YSS+SRAM 2 Y S S + S R AM M
The L/R signals are output without being processed to the MAIN L/R through the AC3D2av.
The L/R signals are output without being processed to the CENTER/SUBWOOFER through the DSP.
The (L+R)/2 signals are output to the FRONT L/R and REAR L/R through the DSP and the SRAM.
When one of the L/R signals is not input, the output level is ­6dB. (Remote control code 7A-89:"2" key [DSP mode])

No.5 SPEAKERS SET
The input is automatically discriminated by signal detection and switched with priorities Coaxial>Optical>Analog.
The L/R signals are output to channels specified by the sub-menu without being processed.
There are the following nine sub-menus items. Signal routes of the sub-menu 1-4 are the same as EFFECT OFF.
But MAIN L/R are signals through the digital circuit.
Signal routes of the sub-menu 5-9 are the same as "2. YSS M" of "No. 2 DSP THROUGH".
However, only MAIN L/R are output in the sub-menu 1-4.

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 a
