SERVICE MANUAL
GX-505 is composed of GX-505 (main unit) and NX-GX505s (speakers).
GX-505VCD is composed of GX-505VCD (main unit) and NX-GX505s (speakers).
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.

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.

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.
WARNING: Laser Safety
This product contains a laser beam component. This component may emit invisible, as well as visible radiation,
which may cause eye damage. To protect your eyes and skin from laser radiation, the following precautions must
be used during servicing of the unit.
1) When testing and/or repairing any component within the product, keep your eyes and skin more than 30 cm away from
the laser pick-up unit at all times. Do not stare at the laser beam at any time.
2) Do not attempt readjustment, disassembly or repair of the laser pick-up, unless noted elsewhere in this manual.
3) CAUTION : Use of controls, adjustments or performance of procedures other than those specified herein may result in
hazardous radiation exposure.

GX-505/GX-505VCD
Laser Emitting conditions:
1) When the Top Cover is removed, and the STANDBY SW is turned to the "ON" position, the laser component will emit
a beam for several seconds to detect if a disc is present. During this time (5-10 sec.) the laser may radiate through the
lens of the laser pick-up unit. Do not attempt any servicing during this period!
If no disc is detected, the laser will stop emitting the beam. When a disc is set, you will not be exposed to any laser
emissions.
2) The laser power level can be adjusted with the VR on the pick-up PWB, however, this level has been set by the factory
prior to shipping from the factory. Do not adjust this laser level control unless instruction is provided elsewhere in this
manual. Adjustment of this control can increase the laser emission level from the device.

CAUTION
When the power to this equipment is turned on with the CD/VCD Mechanical Unit disconnected, the capacitor C255(4700/
16) of the Main P.C.B. (CD/VCD power supply section) is charged. Connecting the CD/VCD P.C.B. in this state may cause
damage to its IC. Therefore, when installing the CD/VCD Mechanical Unit, be sure to discharge the capacitor C255(4700/
16) of the Main P.C.B. before making connections. (To discharge it, short the W201 terminal +B and GND with a
resistor(270Ω 1W).)

■ TEST MODE
To facilitate inspection, measurement and location of any faulty point, 6 types of built-in Test Modes are provided,
one for each section.
• System Test Mode : Test mode for the system section. It is also used when entering the test mode for each section.
• Receiver Test Mode : Test mode for the receiver section
• Tape Test Mode : Test mode for the deck section
• CD Test Mode : Test mode for the CD section
• MD Test Mode : Test mode for the MD section (unused for this unit)
• All Function Test Mode : Test mode for all functions
■ SYSTEM TEST MODE
GX-505/VCD
This test mode is used for the system section. Also, this mode must be executed first when entering the test mode
for each section.
Starting Procedure
In the STANDBY mode, press the STANDBY/ON button while pressing the RANDOM button and the PLAY/
PAUSE(CD) button simultaneously. Once the SYSTEM TEST MODE is set, causal factors for the previous power

PURPOSE & OPERATION
Used to check EQ.
Pressing the STANDBY/ON button will set the Equalizer Test mode.
For the details, refer to page 16.
Used to check lighting of all display segments.
At the first pressing of the STANDBY/ON button, all display segments light up and at the
second pressing, this mode is canceled. (The normal operating mode is restored.)
Do not use No. 04 to 23 functions as they are not for servicing.
Used to cancel the test program.
(The normal operating mode is restored when the STANDBY/ON button is pressed.)
Destination display mode
GX-505/GX-505VCD
Equalizer test mode (Test program No. 01)
When the equalizer test mode is set, “GEQ - xxx” is displayed. “xxx” represents the 3 band value of GEQ.
It is possible to set the GEQ value directly, using the buttons on the remote control unit.

[VCD Module condition check]
If the VCD module is in a good condition, the blue background appears on the monitor screen when in the CD test mode.
If the blue background does not appear, the possibility is that the VCD module has failed.
NOTE: None of the components of the VCD module can be supplied separately. Only a VCD module unit (VZ150200) is available.

■ ALL FUNCTION TEST MODE
When ALL FUNCTION TEST MODE is set through SYSTEM TEST MODE, “AUX/MD” appears on the FL display.
The operation condition in this mode will be as follows.
• AUX/MD is used as the input source of the receiver section, which is then set to the Dolby Pro Logic mode (GX505VCD only).
• When a CD is loaded, Full Repeat Play is executed automatically for it.
• When a cassette tape is loaded, Endless Rec Play is executed by the cassette deck automatically.

3. Test tape required
Since head magnetization, dust accumulations, etc.
are likely to introduce error in the various characteristics, it is very important that the heads are properly
demagnetized and cleaned.
Make adjustments of mechanical system, playback
system and recording system in that order.
Except for azimuth adjustment, adjust in the forward
direction.
Adjust using the TAPE TEST MODE (shown on page 16).

(NC)
Power supply for analog circuit (for AD of DSL, PLL, DA output blocks)
(+5)
GND for analog circuit (for AD of DSL, PLL, DA output blocks)
(GND)
EFM signal output
(NC)
With command defaulted : PLL extract clock output PCK when IOSEL=H, frame re-synchronous signal RESY when IOSEL=L
These settings can be reversed by command (RESY when IOSEL=H).
(NC)
Flag signal output
(NC)
Sub-code CRC check result output (H : OK, L : NG)
(NC)
L : Normal mode
(GND)
H : • For internal master clock, VCO2 output clock for jitter adsorbing PLL is used instead of Xtal
oscillation output (X2).
• VCO2 is always fixed to oscillation mode regardless of VCO2 oscillation stop command or
resetting (/RST=L) and Xtal oscillation is stopped.

(NC)
Xtal system when command is defaulted. Signal processing system when command is switched
Mode selecting terminal (GX-505 : +5, GX-505VCD : GND)
Test mode setting terminal (Normal : H)
(+5)
Sub-code data read clock input
(NC)
Sub-code serial output (SBCK effective) when command is defaulted.
