TABLE OF CONTENTSNOTES ON CHIP COMPONENT REPLACEMENT Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be dam-
aged 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.
CAUTIONUse of controls or adjustments or performance of procedures other than those specifi ed herein may result in hazardous radia-tion exposure.
This appliance is classifi ed as a CLASS 1 LASER product.This marking is located on the rear exterior.
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.

SECTION 1SERVICING NOTES
UNLEADED SOLDERBoards requiring use of unleaded solder are printed with the lead-free 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 MARKUnleaded 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 HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electro-static 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.
NOTES ON LASER DIODE EMISSION CHECKThe 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 DIODE AND FOCUS SEARCH OPERATION CHECKDuring normal operation of the equipment, emission of the laser diode is prohibited unless the upper lid is closed while turning on the SW305 (push switch type).The following checking method for the laser diode is operable.
Method Emission of the laser diode is visually checked. 1. Open the upper lid. 2. Push the SW305 as shown in Fig. 1.
Note: Do not push the detection lever strongly, or it may be bent or damaged.
3. Check the object lens for confi rming normal emission of the laser diode. If not emitting, there is a trouble in the automatic power control circuit or the optical pick-up.
In this operation, the object lens will move up and down 2 times along with inward motion for the focus search.

Procedure :1. Turn the power on.2. Input the following signal from Signal Generator to FM an-
tenna input directly.
Carrier frequency : A = 87.5 MHz, B = 98 MHz, C = 108 MHzDeviation : 75 kHzModulation : 1 kHzANT 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. Confi rm that input Frequency of A, B and C detected and auto-
matic scanning stops. The stop of automatic scanning means The station signal is received in good condition.
