HCD-LF1

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. The CLASS 1 LASER PRODUCT MARKING is located on the rear 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.

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.

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.

ATTENTION AU COMPOSANT AYANT RAPPORT

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 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.

LASER DIODE AND FOCUS SEARCH OPERATION CHECK

Carry out the “S curve check” in “CD section adjustment” and check that the S curve waveform is output several times.

NOTE OF REPLACING THE DMB07 BOARD

When replacing the DMB07 board, since the adjustment value is not set up correctly, “Drive Auto Adjustment” can’t be performed. In this case, initialize Memory in the following procedures.

Procedure:

1. Set the test mode. (See page 25)

2. Press the [2] ke y of the remote commander, and set the “DRIVE

MANUAL OPERATION”. (See page 27)

3. Press the [6] key of the remote commander, and set the “2-6,

Memory Check”. (See page 29)

4. Press the [CLEAR] key of the remote commander , and initialize

Memory.

NOTE 1: Regarding the notification symbol “R”

Because the number of the operating buttons of this product are limited, some operations require use of the operating buttons of the remote commander (RM-SP320 supplied with the product). When a specific operation requires use of the operating buttons of the remote commander (RM-SP320), “R” is added to the specific operating procedure in this manual. Example MENU/NO “R” The MENU/NO button of remote commander.

NOTE 2: Incorrect operations may be performed if the test mode is not

entered properly. In this case, press the ?/1 button to turn the power of f, and retry to enter the test mode.

DISC TRA Y LOCK

The disc tray lock function for the antitheft of an demonstration disc in the store is equipped.

Procedure :

1. Press the ?/1 button to turn the set on.

2. Press the FUNCTION “R” button or touch the FUNCTION button to set DVD function.

3. Insert a disc.

4. While the power is ON (excluding the mode of Power-ON Animation mode), touch the x Sensor (on T ouch P anel) and press the A button simultaneously for several seconds.

5. The “Locked” display appears for a while and disc cannot be removed any more even if the A button is pressed.

*To release this mode, repeat the above operation. The

“Unlocked” display appears and the Disc Tray Lock mode is canceled.

Note: When “LOCKED” is displayed, the slot lock is not released by

turning power on/off with the ?/1 button.
