NOTES ON CHIP COMPONENT REPLACEMENT
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be damaged by heat.
FLEXIBLE CIRCUIT BOARD REPAIRING
• Keep the temperature of soldering iron around 270 °C during repairing.
• Do not touch the soldering iron on the same conductor of the circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering or unsoldering.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following safety check before releasing the set to the customer: Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes.). Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers’ instructions to use these instruments.
2. A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2 V AC range are suitable. (See Fig. A)
SAFETY-RELATED COMPONENT WARNING!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.
CAUTION
Use of controls or adjustments or performance of procedures other than those specifi ed herein may result in hazardous radiation exposure.

SECTION 1
SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electro­static break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The
exible board is easily damaged and should be handled with
care.
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead­free mark (LF) indicating the solder contains no lead. (
Caution:
Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 °C higher
than ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 °C.
Caution:
The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful!
• Strong viscosity Unleaded solder is more viscous (sticky, less prone to
ow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc.
• Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.
NOTE OF REPLACING THE IC501, IC502, IC504 AND IC851 ON THE MB BOARD
IC501, IC502, IC504 and IC851 on the MB board cannot exchange with single. When these parts on the MB board are damaged, exchange the entire mounted board.
NOTE OF REPLACING THE IC100 ON THE MB BOARD
Once IC100 on the MB board is exchanged, perform “MODEL & DEST WRITE MODE” (refer page 13) before operating the set.

PRECAUTION WHEN INSTALLING A NEW OP UNIT/PRECAUTION BEFORE UNSOLDERING THE STATIC ELECTRICITY PREVENTION SOLDER BRIDGE
When installing a new OP unit, be sure to connect the fl exible printed circuit board fi rst of all before removing the static electricity preven­tion solder bridge by unsoldering. Remove the static electricity prevention solder bridge by unsoldering after the
exible printed circuit board has already been connected.
(Do not remove nor unsolder the solder bridge as long as the OP unit is kept standalone.)

TEST MODE
[PANEL TEST MODE]
This mode is used to check the fl uorescent indicator tube, LEDs, keys, [MASTER VOLUME / DJ CONTROL] jog, model, destina­tion and software version.
Procedure:
1. Press [ENTER] and [MUSIC] button simultaneously and hold 3 seconds.
2. All LEDs and segments in
uorescent indicator tube are light-
ed up. All RGB LEDs are lighted up in white color.
3. When you want to enter to the software version display mode, press [
+n
] button.
The model information appears on the
uorescent indicator
tube.
• “GSX3” is shown for XXX-GPX33.
• “GSX5” is shown for XXX-GPX55.
• “GSX7” is shown for XXX-GPX77.
• “GSX8” is shown for XXX-GPX88.
** If display shown information below, please proceed with
[MODEL & DEST WRITE MODE] to write model & destina­tion.
• “GSX8(T)” is shown for XXX-GPX33/55/77/88.
XXX = MHC / LBT Press [
+n
] button again to view the destination information.
4. During the destination information display, press [
+n
] button.
Each time [
+n
] button is pressed, the fl uorescent indicator tube shows the version of each category software in the follow­ing sequence: SC, MTK, UI, PF, SYS, CD, CDMA, CDMB, ST, TA, TAS, TM, BTM, BT, NFC, and return back to model information display.

• “V” value increases in the manner of 0, 1, 2, 3... if [MASTER VOLUME / DJ CONTROL] knob is turned clockwise, or it decreases in the manner of 0, 9, 8, 7... if [MASTER VOLUME / DJ CONTROL] knob is turned counterclockwise.
8. When [ENTER] button is pressed after all LEDs and segments
in
uorescent indicator tube light up, alternate segments in
uorescent indicator tube and LEDs would light up, all RGB LEDs would light up in red color. If you press [ENTER] button again, another half of alternate segments in
uorescent indicator tube and LEDs would light up, all RGB LEDs would light up in green color. Pressing [ENTER] button again would cause all segments in
uorescent indicator tube and LEDs light up, all RGB LEDs would light up in blue color. Pressing [ENTER] button again would turn off all segments in
uores-
cent indicator tube and all LEDs including RGB LEDs.

Protector Message
Description
E01 “AMP OCP” The over current condition to
MOSFET occurs by defect of MOSFET or defect of PS output line.
E03 “POWER
SUPPLY”
Defect of power supply circuit to AMP
E04 “DC DETECT” DC appears in SP terminal by
defect of AMP IC and MOS­FET.

Note:
1. CD Block is basically constructed to operate without adjustment.
2. Use YEDS-18 disc (Part No. 3-702-101-01) unless otherwise indicat­ed.
3. Use an oscilloscope with more than 10 M
impedance.
4. Clean the object lens by an applicator with neutral detergent when the
signal level is low than speci
ed value with the following checks.
5. Check the focus bias check when optical pick-up block is replaced.
FOCUS BIAS CHECK
Procedure :
1. Connect the oscilloscope to CN507 pin 6 (RFMON) and
CN507 pin 3 (GND) on the MB board.
2. Press the [
?/1

press the [CD] button to select CD function.
3. Set disc (YEDS-18) and press the [
u

FM AUTO STOP CHECK
Procedure:
1. Turn the power on.
2. Input the following signal from Signal Generator to FM an­tenna input directly.
Carrier frequency : A = 87.5 MHz, B = 98 MHz, C = 108 MHz Deviation : 75 kHz Modulation : 1 kHz ANT input : 35 dBu (EMF)
Note:
Please use 75 ohm “coaxial cable” to connect SG and the
set. You cannot use video cable for checking.
Please use SG whose output impedance is 75 ohm.
3. Set to FM tuner function and scan the input FM signal with
automatic scanning.
4. Con
rm that input Frequency of A, B and C detected and
automatic scanning stops.
The stop of automatic scanning means “The station signal is received in good condition”.
