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.
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

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.
IMPORTANT  NOTICE  FOR  OPERATION  CHECK
Before performing an operation check on this model, make sure 
you fi rst attach inner door to prevent the laser beam from shining 
directly into the eyes.
Additionally, before disassembling this model, make sure you re-
move the power cord and confi rm that no electricity is fl owing 
through this model.
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.
ADVANCE  PREPARATION  WHEN  CONFIRMING  OP-
ERATION
In order to perform the operation checking, all the units contained 
in this unit are needed.
ABOUT  THE  LENS  CLEANING
Don’t do the lens cleaning with the cotton bud etc. It causes the 
trouble.
RELEASING  THE  DISC  LID  LOCK
The disc lid 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.  Press the [HOME] button on the remote commander to enter 
the home menu.
3.  Touch the [
x
] sensor, press the [
Z
] button simultaneously 
and hold down until “D. OFF” displayed on the fluorescent 
indicator tube (around 5 seconds).
Note: When “D LOCK” is displayed, the disc lid lock is not released by 
turning power on/off with the [?/1] button.
CAPACITOR  ELECTRICAL  DISCHARGE  PROCESSING
When checking the board, the electrical discharge is necessary for 
the electric shock prevention.
Connect the resistor to both ends of respective capacitors.
