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.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specifi ed herein may result in hazardous radia-
tion exposure.
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.
TE
L 13942296513
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

Self-Diagnosis Function
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.

service facility and give the error code. "xxxx" represents
an error code (number).
FAN ERR Check that the ventilation holes on the rear of the player
are not blocked.
Place the player in a location with adequate ventilation
to prevent heat build-up in the player.
When turning the player on,
"SYSTEM ERROR" appears in the front panel display.
, Disconnect the power cord and wait for a while, then re-connect the
power cord.
CAUTION
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.
