NOTES 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.

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.

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.

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.

RELEASING THE DISC TRAY LOCKThe disc tray lock function for the antitheft of an demonstration disc in the store is equipped.

Releasing Procedure:1. Press [?/1] button to turn the power on.2. Press the [FUNCTION] button to select CD function.3. While pressing the [x] button for more 5 seconds.4. The message CHILD LOCK OFF is displayed and the disc

tray is unlocked.

Note: When CHILD LOCK ON is displayed, the slot lock is not re-leased by turning power on/off with the [?/1] button.

*: Since the HCD-EX99: E2 and E51 models have their model number labels marked directly on the back panel, the model number labels have no relative part numbers.

Because of this, determine the model through the marked model number when comparing the difference between these models.

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 electric-ity prevention solder bridge by unsoldering. Remove the static electricity prevention solder bridge by unsolder-ing after the fl exible printed circuit board has already been con-nected. (Do not remove nor unsolder the solder bridge as long as the OP unit is kept standalone.)

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 re-ceived in good condition.
