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

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

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.

■ 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.

2. Leakage Current Measurement (For 120V Model only). 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.

2. BEGINNING AND CANCELLATION

(1) STARTING UP THE FUNCTION AND THE DISPLAY

After starting up, menu No. 1 is selected.

A. How to start diagnostic program

Using the front panel keys of the main unit.

Hold down the "INPUT MODE" and "+" keys simultaneously, and press the "STANDBY/ON" key; submenu No. 1 of diagnosis main menu No. 1 will start.

B. Settings for start-up of diagnostic program

The settings used when starting the diagnostic program are as follows.

C. Start-up display

The information of the protection function appears on the front panel display of the main unit.

● 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.

Appears when the current protection function has been activated. 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. 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 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.

● 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.

(2) RELEASING METHOD

The diagnosis function can be released 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.

DSP-A595

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

The main menu can be changed cyclically by using the "TV SPORTS" and "DISCO" keys, and the submenu, by using the "ROCK CONCERT" and "CONCERT HALL" keys. The "DISCO" or "CONCERT HALL" key will increase the main or submenu number.

(2) Other functions available while diagnosis function is active

Listed below are the other functions available while the diagnosis function is active. ¥ Selecting input source (Tape monitor/Ext. decoder)

¥ Adjusting effect level (Center, Rear, Sub-woofer) ¥ Adjusting master volume ¥ Muting on/off ¥ Power on/off

(3) Diagnosis default status

When not otherwise specified, default settings and values in each menu are as follows: ¥ All SPEAKERS : LARGE

¥ ALL electronic VRs : 0dB ¥ DYNAMIC RANGE : MAX ¥ LFE LEVEL : 0dB (—10dB DOLBY DIGITAL LFE) ¥ CENTER DELAY : 0ms

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

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)

: This shows that the device is not operating.

2. DSP 0dB

MAIN L/R, CENTER/SUBWOOFER/LFE, FRONT L/R and REAR L/R pass through the DSP without being processed.

: This shows that the device is not operating.

All segments are turned on and off to detect defects in the FL driver and FL display segments. Then the FL driver operation is checked by the dimmer control. Finally, all segments are turned on and off alternately (in lattice form), to check for a short-circuit between adjacent segments.

No.7 MANUAL TEST

The noise generator built into the DSP outputs test noise from the channel specified by the submenu.

No.8 FACTORY PRESET

The menu is used to reserve whether or not to set the back-up data for the effect level, delay time and so on to the factory preset state. The Signal is processed with EFFECT OFF.

1. INHIBIT: The back-up data is not initialized. To keep the data set by the user, check that this mode has been selected and cancel the self diagnosis function.

2. RESERVED: When the self diagnosis function is canceled, the backup data is initialized to the factory preset state. For the contents of the initialization, refer to page 18. The protection data is also reset.

No.9 AD DATA CHECK

The A/D conversion values of the main CPU which detects key scan, protection, etc. are displayed in % (100%: 5V). All signal processing before this menu is executed will be held. The keys on the main unit cannot be operated to detect the values of all keys in the K1/K2/K3/K4. Turning the rotary encoder (input selector on the main unit) will switch the submenu.

Cautions:

1.If K1/K2/K3/K4 are more than ±4% from the reference values, normal operation will not be executed.

2.If DC and PS are outside the normal values, the protection function will operate and power will turn off.

[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.

No.11 CPU VERSION/CHECK SUM/PORT INFO/EXIT DIAG

The check sum, version and port setting of main CPU/DSP CPU are displayed. The signal is EFFECT OFF. Operating the submenu will finish self-diagnosis, and ordinary operation mode will be restored. The suffix letter ("B" in the following) of version indication is for compatibility of communications between the main and DSP microprocessors. Combining microprocessors with different suffixes will make normal operation impossible.
