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

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.

SECTION  1
SERVICING  NOTES
NOTES  ON  HANDLING  THE OPTICAL  PICK-UP  
BLOCK  OR  BASE  UNIT
The laser diode in the optical pick-up block may suffer electro-
static 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 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)
 : 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 viscous (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.

*  When 1080/24p monitor is nothing, 1080i (59.94Hz or 50Hz) 
can use instead of 1080/24p.
 
However this is temporary correspondence.
2. BLX-204
Procedure:
1.  Select 1080i (59.94Hz or 50Hz).
2.  Play “4.Motion picture”.
3.  Check whether player can play back or not (Check the picture 
and sound output).
3. CD

Procedure:
Check whether player can play back or not (Check the sound out-
put).
4.  HLX-513/514 (NTSC), HLX-506/507 (PAL)
Procedure:
1.  After displayed Main Menu, select “1.Video Signal”.
2.  Play “1.Color bar 100%” (Check the picture and sound out-
put).
3.  Return to Menu.
4.  Play “Demonstration 4:3” or “Demonstration 16:9” (Check the 
picture and sound output).
NOTE  OF  REPLACING  THE  IC101,  IC304,  IC307, 
 
IC501  AND  IC702  ON  THE  MB-141  BOARD
IC101, IC304, IC307, IC501 and IC702 on the MB-141 board 
cannot exchange with single. When these parts are damaged, ex-
change the complete mounted board.
NOTE  OF  REPLACING  THE  IC106,  IC107,  IC206  AND  
IC207  ON  THE  MB-141  BOARD
Replacement of IC106, IC107, IC206 and IC207 on the MB-141 
board used in this unit requires a special tool.
RELEASING  THE  DISC  TRAY  LOCK
The disc tray lock function for the antitheft of an demonstration 
disc in the store is equipped.
Releasing Procedure:
1.  Press the [
?/1
] button to turn on the system.
2.  Touch the [FUNCTION] sensor to select “BD/DVD”.
3.  Touch the [
x
] and [
Z
] sensors simultaneously and hold down 
unit “DEMO OFF” displayed on the fluorescent indicator tube 
(around 5 seconds).
Note: When “DEMO LOCK” is displayed, the disc tray lock is not re-
leased by turning power on/off with the [?/1] button.
ABOUT  THE  LENS  CLEANING
Do not do the lens cleaning with the cotton bud etc. It causes the 
trouble.
