RX-Z1/DSP-AZ1 SERVICE MANUAL
For the details of RAV2000Z1 (U, C models), refer to the
RAV2000 SERVICE MANUAL #100770.
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 or 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.
Please note that no program is written into the
microprocessor supplied for servicing. Therefore, it is
necessary to write the program when the microprocessor
is replaced. (For the details, refer to "UPDATING
FIRMWARE".)

Components having special characteristics are marked s
and must be replaced with parts having specifications equal
to those originally installed.
2. Leakage Current Measurement (For 120V Models Only)
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated INSULATING
from supply circuits. TABLE
G Meter impedance should be equivalent to 1500 ohm shunted G Leakage current must not exceed 0.5mA.

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 REA-
SON 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 food.

· Starting DIAG
Press the "STANDBY/ON" key while simultaneously
RX-Z1/DSP-AZ1
pressing those two keys of the main unit as indicated in the
figure below.

· Starting DIAG in the protection cancel
mode
If the protection function works and causes hindrance to
trouble diagnosis, cancel the protection function as
described below, and it will be possible to enter the DIAG
mode. (The protection functions other than the excess
current detect function will be disabled.)
Press the "STANDBY/ON" key while simultaneously
pressing those two keys indicated in the figure on the
previous page. At this time, keep pressing those two keys
for 3 seconds or longer.
In this mode, the "SLEEP" segment of the FL display of the
main unit flashes to indicate that the mode is DIAG mode
with the protection functions disabled.
CAUTION!
Using this product with the protection function disabled
may cause damage to itself. Use special care for this point
when using this mode.
· Canceling DIAG
[1] Before canceling DIAG, execute setting for PRESET of
DIAG menu No.11 (Memory initialization inhibited or
Memory initialized).
* In order to keep the user memory stored, be sure to
select INHIBITED (Memory initialization inhibited).
[2] Turn off the power by pressing the "STANDBY/ON"
key of the main unit.
· Display provided when DIAG started
When the monitor is connected, DIAGNOSTIC MENU
appears on its screen as shown in the figure. (It remains
on display until DIAG is cancelled.)

The history of the protection function and the version (1
alphabet) appear in the upper section and the checksums
(4 figures and alphabets) of the main microprocessor and
sub-microprocessor appear in the lower section, followed
by the DIAG menu (sub-menu of ANALOG BYPASS of
No.1 YSS938 THR) after a few seconds.

amplifier.
Supplementary information: As current of the power
transistor is detected, the abnormal channel can be
identified by checking the current detect transistor.
Turning on the power without correcting the abnormality
will cause the protection function to work immediately and
the power supply will instantly be shut off.

* Additional causes of protection can be due to loose
connections, associated components, CPU, etc.
* For the protection voltage value, refer to DIAG menu
No.12 described later.
· History of protection function
When the protection function has worked, its history is
stored in memory with a backup. Even if no abnormality
is noted while servicing the unit, an abnormality which
has occurred previously can be defined as long as the
backup data has been stored.
The history of the protection function is cleared when
DIAG is cancelled by selecting PRESET RESERVED
(Memory initialized) of DIAG menu No.11 or when the
backup data is erased.
· Display during menu operation
During the DIAG operation, the menu list described in the
section of the startup screen appears on the
superimposed screen and the function at work is indicated
on the FL indicator. The contents displayed during the
function operation are described in the later section on
details of functions.
