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 manufactur ers’ 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 v oltmeter. The “limit” indication is 0.75 V, so analog meters must hav e 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)
To Exposed Metal Parts on Set
Laser component in this product is capable of emitting radiation exceeding the limit for Class 1.
This appliance is classified as a CLASS 1 LASER product. This marking is located on the bottom exterior.
CAUTION
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
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 the 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-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.
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 viscou-s (sticky, less prone to flow) 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.
ATTENTION AU COMPOSANT AYANT RAPPORT
LES COMPOSANTS IDENTIFIÉS PAR UNE MARQUE 0 SUR LES DIAGRAMMES SCHÉMATIQUES ET LA LISTE DES PIÈCES SONT CRITIQUES POUR LA SÉCURITÉ DE FONCTIONNEMENT. NE REMPLACER CES COM- POSANTS QUE PAR DES PIÈCES SONY DONT LES NUMÉROS SONT DONNÉS DANS CE MANUEL OU DANS LES SUPPLÉMENTS PUBLIÉS PAR SONY.

SERVICING NOTE

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 flexible board is easily damaged and should be handled with care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused on the disc reflective 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.
DISC TRA Y LOCK
The disc tray lock function for the antitheft of an demonstration disc in the store is equipped.
Setting Procedure :
1. Press the ?/1 button to turn the set on.
2. Press the [FUNCTION] button to set DVD function.
3. Insert a disc.
4. Press the
x button and the A button simultaneously for five
seconds.
5. The message “LOCKED” is displayed and the tray is locked.
Releasing Procedure :
1. Press the x button and the A button simultaneously for fi ve seconds again.
2. The message “UNLOCKED” is displayed and the tray is unlocked.
Note: When “LOCKED” is displayed, the tray lock is not released by
turning power on/off with the ?/1 button.
Note on MAIN board replacement
New part of EEP ROM (IC1103) on the MAIN board cannot be used. Therefore, if the mounted MAIN board (A-1144-739-A, etc.) is replaced,
exchange new EEP ROM (IC1103) with that used before the replacement.
Self-diagnosis Function
(When letters/numbers appear in the display)
When the self-diagnosis function is activated to prevent the system from malfunctioning, a 5­character service number (e.g., C 13 50) with a combination of a letter and 4 digits appears on the screen and the front panel display. In this case, check the following table.
C:13:50
First 3 characters of the service number
C 13 The disc is dirty.
C 31 The disc is not inserted correctly.
E XX (xx is a number)
When displaying the version number on the screen
When you turn on the system, the version number [VER.X.XX] (X is a number) may appear on the screen. Although this is not a malfunction and for Sony service use only, normal system operation will not be possible. Turn off the system, and then turn on the system again to operate.
Cause and/or corrective action
,Clean the disc with a soft cloth
,Restart the system, then re-insert
the disc correctly.
To prevent a malfunction, the system has performed the self­diagnosis function.
,Contact your nearest Sony
dealer or local authorized Sony service facility and give the 5­character service number.

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

•Voltages and wav ef orms are dc with respect to ground un­der no-signal (detuned) conditions.
•Voltages and waveforms are dc with respect to ground in service mode.
•Waveforms are taken with a oscilloscope. Voltage v ariations ma y be noted due to normal production tolerances. no mark : DVD STOP * : Impossible to measure
•Voltages are taken with VOM (Input impedance 10 MΩ).
• Circled numbers refer to waveforms.
