Boards 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)

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.

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be

damaged by heat.

• 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.

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 rear or bottom exterior.

Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation
exposure.

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.

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 pick-
up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.

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

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.

1. Press the  

x  

button and the  

A 

 button simultaneously for five

seconds again.

2. The message “UNLOCKED” is displayed and the tray is

unlocked.

When “LOCKED” is displayed, the tray lock is not released by turning
power on/off with the  ?/1  button.

New part of EEP ROM (IC1103) on the MAIN board cannot be used.
Therefore, if the mounted MAIN board (A-1188-583-A) is replaced,

exchange new EEP ROM (IC1103) with that used before the replacement.

When the self-diagnosis function is activated to 
prevent the system from malfunctioning, a 5-
character 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.

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.

C 13

The disc is dirty.

,Clean the disc with a soft cloth 

C 31

The disc is not inserted correctly.

,Restart the system, then re-insert 

the disc correctly.

E XX

(xx is a number)

To prevent a malfunction, the 
system has performed the self-
diagnosis function.

,Contact your nearest Sony 

dealer or local authorized Sony 
service facility and give the 5-
character service number.
