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.

protection relay of this unit according to the following
procedure.
a. Remove the top cover. (Refer to “1. Top Cover
Removal”on p.15.)
b. Remove 1 screw (C) and 4 screws (D). (Fig. 7)
c. Replace the flexible flat cable connecting CB253 of
MAIN (3) P.C.B. and CB308 or FUNCTION (1) P.C.B.
with the extension cable specified below. (Fig. 9)
Extension cable: MF136300
d. Raise the MAIN P.C.B. (Fig. 10)
e. In this state, the power transistor and speaker
protection relay can be replaced.

•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 above. 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.9 (Memory initialization inhibited or
Memory initialized).
* In order to keep the user memory stored, be sure to
select PRESET INHIBITED (Memory initialization
inhibited). Protection history will remain memory.
[2] Turn off the power by pressing the “STANDBY/ON”
key of the main unit.

Cause: An excessive current flowed through the power
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.
Note)
•Applying the power to a unit without correcting the
abnormality can be dangerous and cause additional
circuit damage.
•The output transistors in each amplifier channel
should be checked for damage before applying any
power.
•Amplifier current should be monitored by measuring
across the emitter resistors for each channel.

•Display during menu operation
During the DIAG operation, 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
•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.9 or when the
backup data is erased.

4. SPEAKERS SET
The input signal is automatically identified and switched in
the priority order of dts →DOLBY DIGITAL →AAC →
PCM AUDIO →Analog (A/D) according to the signal
detection.
The signals output from the DSP block are the same as 1.
DSP THROUGH: YSS 0dB.
LARGE: This mode is used with a speaker with high
bass reproduction performance (a large
unit). Full bandwidth signals are output.
SMALL: This mode is used with a speaker with low
bass reproduction performance (a small
unit). The signals of 90Hz or less are mixed
into the channel specified by LFE/BASS.
NONE: This mode is used with no center speaker.
The center content is reduced by 3dB and

Segment conditions of the FL driver and the FL tube are
checked by turning ON and OFF all segments. Next, the
operation of the FL driver is checked by using the dimmer
control. Then a short between segments next to each
other is checked by turning ON and OFF all segments
alternately (in lattice). (In the above example, the
segments in the second row from the top are shorted.)
7. DISPLAY CHECK
This program is used to check the FL display section. The
display condition varies as shown below according to the
sub-menu operation. The signals are processed using
EFFECT OFF (The L/R signal is output using ANALOG
MAIN BYPASS.)
