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 ﬂ exible 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 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.

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 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.

NOTE THE CN400 ON THE DAB PS BOARD REPLACING

CN400 on the DAB PS board cannot exchange with single. When CN400 on the DAB PS board is damaged, exchange the entire mounted board.

About the Hard Disk Drive

Because of its high storage density, the hard disk can read and write data a very high speeds. It is, however, easily damaged by mechanical vibration, shock, or dust. Although the hard disk is equipped with safety mechanisms to prevent the lost of data due to these factors, the following precautionsshouldbetakenduringthehandlingofthe unit.

• Donotsubjectthe unittostrongshocksorvibrations.

• Do not place the unit in a location subject to mechanical

vibration or at an unstable location.

• Do not move the unit while the power cord is connected to a

wall outlet.

• Do not attempt to replace or upgrade the hard disk drive by

yourself, as this may cause the unit to malfunction. Sony cannot provide compensation for any loss of data caused by a damaged hard disk drive.

On data back up

Audio data and system settings stored on the unit’s hard disk may be lost during repairs done to the unit. Before taking the unit in for repairs, it is recommended that you record the settings on a piece of paper and that you use the Back Up function to back up the data to a shared folder on your computer or a USB hard disk drive (see “Backing up and restoring audio data” on page 104). Data on the unit’s HDD is subject to damage during normal operations. To prevent the loss of data, you should back up the data on a regular basis. Please note that we cannot take responsibility for any data that may be lost or repairs.

Cleaning the cabinet

slightly moistened with a mild detergent solution. Do not use any type of abrasive pad, scouring powder, or solvent, such as thinner, benzine, or alcohol.

Note on the power cord

DISCHARGE PROCESSING

1. Switching power block on primary side of main board Though high voltage of 280V is applied to the electrolytic capacitor (C205), in about 3 seconds after the AC cord was unplugged, the

voltage will lower to 3 to 4V. However, in the case of standalone main board, the discharge time will be long because of small load. The voltage at this time is about 290V. The voltage becomes half in about 20 seconds after the AC cord was unplugged. After that, in about 5 seconds, the voltage will lower

to about 3V rapidly. Then, the discharge slows and accordingly the forced discharge processing is necessary.

• Forced discharge processing method

Connect a resistor such as 100Ω 3W to the terminals of C205 and execute the discharge processing. (Discharge for about 10 sec-

onds)

Note: The potential of about 145V exists across aluminum case of C205. You could get an electric shock if you touch the aluminum case of C205.

2. Power block on secondary side of main board In about 3 seconds after the AC cord was unplugged, almost all potentials will lower to below 3V, but after that the discharge slows and

accordingly the forced discharge processing is necessary.

• Forced discharge processing method

Connect a resistor such as 100Ω 3W to the terminals of C308 and C310, and execute the discharge processing. (Discharge for about

5 seconds)

For electrolytic capacitors other than C205, 308 and 310, the discharge processing is executed simultaneously with the above discharge

processing, and therefore the forced discharge processing is not necessary.
