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.

1. Critical Components Information
Components having special characteristics are marked s
and must be replaced with parts having specifications equal
to those originally installed.
WALL
OUTLET
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
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 food.

• Starting DIAG
Press the “POWER ” (STANDBY/ON) key of the main unit while pressing the
“FM/AM ” key and the “INPUT MODE ” key simultaneously, and DIAG will be
activated.
• Starting DIAG in the protection cancel mode
If the protection function activates and causes hindrance to trouble diagnosis,
disable the protection function as described below, and it will be possible to enter
the DIAG mode. (The protection function other than the excess current detect
function will be disabled.)
Keys of main unit
FM/AM
INPUT MODE
Turn on the power while
pressing these keys.
Press the “POWER" (STANDBY/ON) key while pressing the “FM/AM" key and
the “INPUT MODE" key simultaneously. At this time, keep pressing the “FM/AM"
key and the “INPUT MODE" for 3 seconds or longer.
RX-V420/RX-V420RDS/
In this mode, “SLEEP” in the FL display of the main unit flashes.
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
Turn off the power by pressing the “POWER” (STANDBY/ON) key of the main unit or the “STANDBY” key of the remote
control unit.
CAUTION: When canceling this function, check that DIAG menu No.10 PRESET (memory initialization inhibited/reserved)
has been set. [To keep the user memory, be sure to select “INHI” (initialization inhibited) from the No.10 PRESET menu
before canceling the DIAG function.]
• Display at the start of DIAG
On the FL display of the main unit, an opening message (including the version and the protection history) appears for a few
seconds followed by the diagnostic menu display of 1. ANALOG BYPAS.
Opening message
When there is no
protection history (*1)
DIAG menu display
Version (1 alphabet)
After a few
seconds
(*1) If a protection function history has been recorded, the type of the protection function and the voltage value recorded last
are displayed.
If the protection function activates after DIAG has been started and the power is turned off;
When the protection function (*2) activates, the protection function history appears on the display and the power turns off.
Repair the faulty parts according to the displayed history.
(*2) When an excess current or any other faulty condition is found with the power source, DC, etc., the protection function
forces the power to turn off.
I PROTECT display
(When the power is turned on without this abnormality corrected, the protection

Cause: There is an abnormality in the power supply section (voltage).
Supplementary information: As the power from the following sources is detected, it
is possible to determine where an abnormality exists.

Cause: A DC output from the power amplifier of any channel is detected.
Besides the above possible causes, the cause may be a disconnected connector or around the CPU.
PS PRT and DC PRT displays include the abnormal A/D value in % (voltage value obtained by considering 5V as 100%).
Concerning this value, refer to DIAG menu No.11 AD DATA CHECK.
• Protection history
When the protection function has activated, its history is stored in memory with a memory backup. Even when no
abnormality is noted while the unit is being serviced, an abnormality which has occurred previously can be defined as
long as the backup data has been stored. The protection history should always be cleared before returning the unit
from service.
The protection history is cleared when DIAG is cancelled by selecting "RSRV" (Memory initialization) from the setting
items of the DIAG menu No.10 PRESET or when the backup data is erased.
• Operation procedure of DIAG menu and SUB-MENU
There are 14 MENU items and some SUB-MENU items as well.
DIAG menu selection

Initialization of the back-up RAM is reserved. (Actually, initialization is executed
next time when the power is turned on.) Select this sub-menu to reset when
shipped out of the factory or to reset RAM.

This menu is used to display the A/D conversion value of the main CPU which detects panel keys of the main unit and
protection functions in % using the sub-menu. (Reference voltage 5V as 100%) During signal processing, the condition
before execution is maintained.
When in 0/1/2 page, it is not possible to operate the keys of the main unit because the values of all keys are detected. During
signal processing, the condition before execution of this menu is maintained.
DC/PS (Detection of the protection function) [REMOTE CONTROL CODE: 7A-0B
(CD SKIP-)]
DC: DC detect protection value (Normal value: 3 to 35)
PS: Power voltage protection value (Normal value: 120 to 170)
* If DC or PS is out of the normal value range, the protection function activates
to turn off the power relay.

13. DSP RAM CHECK
This menu is used to self-diagnose whether or not bus connection of YSS928 (IC801) and the external RAM (IC802) is made
properly.
During signal processing, the status before execution of this menu is maintained.
Bus Check [Remote control code: 7A-0A (CD SKIP+)]
The address bus and the data bus are checked and the connection condition is
displayed.
When no error is detected, "NOER" appears on display.

14. MICROPROCESSOR INFORMATION
The version, checksum and the port specified by the microprocessor are displayed. The signal is processed using EFFECT
OFF. The checksum is obtained by adding the data at every 16 bits for each program area and expressing the result as a 4figure hexadecimal data.

■ AMP ADJUSTMENT
Confirmation and Adjustment of Idling Current of
Main (1) P. C. B.
0.1mV ~ 5mV
(DC)
• Right after the power is turned on, confirm that the
voltages at R53, R55, R59, R65 and R67 are between
0.1mV and 5mV.
• If any exceed 5mV, cut R27, R33, R39, R43 or R47.
• Reconfirm that they are between 0.1mV and 5mV.
• The voltages should be 0.1mV ~ 5mV after the power
has been on for 60 minutes.
