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  CHECK-OUT
After correcting the original service problem, perform the follow-
ing safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs, 
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.

LEAKAGE  TEST
The AC leakage from any exposed metal part to earth ground and 
from all exposed metal parts to any exposed metal part having a 
return to chassis, must not exceed 0.5 mA (500 microamperes.). 
Leakage current can be measured by any one of three methods.
1.  A commercial leakage tester, such as the Simpson 229 or RCA 

WT-540A. Follow the manufacturers’ instructions to use these 
instruments.

2.  A battery-operated AC milliammeter. The Data Precision 245 

digital multimeter is suitable for this job.

3.  Measuring the voltage drop across a resistor by means of a 

VOM or battery-operated AC voltmeter. The “limit” indication 
is 0.75 V, so analog meters must have an accurate low-voltage 
scale. The Simpson 250 and Sanwa SH-63Trd are examples 
of a passive VOM that is suitable. Nearly all battery operated 
digital multimeters that have a 2 V AC range are suitable. (See 
Fig. A)

CAUTION
Use of controls or adjustments or performance of procedures 
other than those specifi ed herein may result in hazardous radia-
tion exposure.

The use of optical instruments with this product will increase eye hazard. As the laser 
beam used in this Blu-ray Disc/DVD player is harmful to eyes, do not attempt to 
disassemble the cabinet.
Refer servicing to qualified personnel only.
US and Canadian models

This label is located on the laser protective housing inside the enclosure.

This appliance is classified as a CLASS 3R LASER product.
Visible and invisible laser radiation is emitted when the laser protective housing is 
opened, so be sure to avoid direct eye exposure.

This appliance is classified as a CLASS1 LASER product. This marking is located 
on the rear exterior.

When the self-diagnosis function is activated to prevent the player 
from malfunctioning, an error code appears in the front panel display, 
or just 

 appears without any messages on the entire screen.

In these cases, check the following.

Exxxx
SYS ERR

Contact your nearest Sony dealer or local authorized Sony 
service facility and give the error code. “xxxx” represents 
an error code (number).

FAN ERR

s Check that the ventilation holes on the rear of the player 

are not blocked.

s Place the player in a location with adequate ventilation 

to prevent heat build-up in the player.

, Disconnect the power cord and wait for a while, then re-connect the 

power cord.
