SAFETY-RELATED COMPONET 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.

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.

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 ﬂ 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.

NOTES ON LASER DIODE EMISSION CHECK

The laser beam on this model is concentrated so as to be focused on the disc reﬂ ective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.

Laser component in this product is capable of emitting radiation exceeding the limit for Class 1.

This appliance is classiﬁ ed as a CLASS 1 LASER product. This marking is located on the rear exterior.

CAUTION

Use of controls or adjustments or performance of procedures other than those speciﬁ ed herein may result in hazardous radia- tion exposure.

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 ﬂ exible board is easily damaged and should be handled with care.

SERVICING NOTES

Notes on Disconnecting Between the OP Section (DVBU101) and the DMB18 Board

Note: When disconnecting between the OP section (DVBU101) and the DMB18 board, be sure to make a solder brige for electrostatic

prevention as illustrated in the ﬁ gure (before disconnection). On the contrary, when installing the OP section, never remove the solder bride until the OP section and the DMB18 board are connected. Be sure to remove the solder bridge after the OP section and the DMB18 board have been connected.

Perform solder bridging to prevent damage by electrostatic discharge when handling the BU as a single unit.

Service Position for the DVD Mechanism Deck Section

Refer to the ﬁ gure given below when disassembling the DVD mechanism deck section.

Notes on Installing the Two Cooling Fans (FAN901 and FAN902) (HCD-GZR8D/GZR9D)

Note: The HCD-GZR8D/GZR9D has two cooling fans (FAN901 and FAN902) used. The connectors of these fans have the same color

and the same number of pins. When installing these fans, check the marking of CN601 and CN602 on the MAIN board and ensure that they are located correctly. The CN601 on the MAIN board is to be attached with the connector of FAN901 where as the CN602 is to be attached with the

connector of FAN902.

MECHANICAL ADJUSTMENTS

Precaution

1. Clean the following parts with a denatured alcohol-moistened swab:

record/playback heads pinch rollers erase head rubber belts capstan idlers

2. Demagnetize the record/playback head with a head demagnetizer.

3. Do not use a magnetized screwdriver for the adjustments.

4. After the adjustments, apply suitable locking compound to the parts adjusted.

5. The adjustments should be performed with the rated power supply voltage unless otherwise noted.

Procedure:

1. Connect an oscilloscope to CN105 pin 6 (RFMON) and CN105 pin 3 (GND) on the DMB18 board.

2. Turn the power on.

3. Set the test disc (refer to the TEST DISC LIST) on the tray and press [Y] button to playback.

4. Conﬁ rm that oscilloscope waveform is clear and check RFMON signal level is correct or not.

Note: A clear RFMON signal waveform means that the shape

“◊” can be clearly distinguished at the center of the waveform.

Procedure:

1. Turn on the set.

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 dBμ (EMF)

Note: Use 75 ohm coaxial cable to connect signal generator and

the set. You cannot use video cable for checking. Use signal generator whose output impedance is 75 ohm.

3. Set to FM tuner function and tune A, B and C signals.

4. Conﬁ rm “TUNED” is lit on the display for A, B and C

signals.

When the selected station signal is received in good condition, “TUNED” is displayed.

Note:

• All capacitors are in μF unless otherwise noted. (p: pF) 50 WV or less are not indicated except for electrolytics and tantalums.

• All resistors are in Ω and 1/4 W or less unless otherwise speciﬁ ed.

• 2 : nonﬂ ammable resistor.

• C : panel designation.

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.)

• A : B+ Line.

• B : B– Line.

• Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions. no mark : FM

* : Impossible to measure

• Voltages are taken with VOM (Input impedance 10 MΩ).

Voltage variations may be noted due to normal production

tolerances.

• Waveforms are taken with a oscilloscope.

Voltage variations may be noted due to normal production

tolerances.

• Circled numbers refer to waveforms.

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 ﬂ 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.

• Waveforms
