SAFETY  CHECK-OUT
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 0.75V, 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 2V AC range are suitable. (See Fig. A)
1.  Check the area of your repair for unsoldered or poorly-soldered 
connections. Check the entire board surface for solder splashes 
and bridges.
2.  Check the interboard wiring to ensure that no wires are “pinched” 
or contact high-wattage resistors.
3.  Look for unauthorized replacement parts, particularly transistors, 
that were installed during a previous repair. Point them out to 
the customer and recommend their replacement.
4.  Look for parts which, though functioning, show obvious signs 
of deterioration. Point them out to the customer and recommend 
their replacement.
5.  Check the line cord for cracks and abrasion. Recommend the 
replacement of any such line cord to the customer.
6.  Check the B+ voltage to see it is at the values specified.
7.  Check the antenna terminals, metal trim, “metallized” knobs, 
screws, and all other exposed metal parts for AC leakage. Check 
leakage as described below.
After correcting the original service problem, perform the following 
safety checks before releasing the set to the customer:

WARNING!!
WHEN  SERVICING,  DO  NOT  APPROACH  THE  LASER 
EXIT  WITH  THE  EYE  TOO  CLOSELY.  IN  CASE  IT  IS 
NECESSARY  TO  CONFIRM  LASER  BEAM  EMISSION, 
BE  SURE  TO  OBSERVE  FROM  A  DISTANCE  OF MORE   
THAN   25  cm  FROM  THE  SURFACE  OF  THE OBJEC-
TIVE  LENS  ON  THE  OPTICAL  PICK-UP  BLOCK.
SAFETY-RELATED  COMPONENT  WARNING!!
COMPONENTS  IDENTIFIED  BY  MARK  0  OR  DOTTED  LINE  
WITH  MARK  
0  ON  THE  SCHEMATIC  DIAGRAMS  AND  IN  
THE  PARTS  LIST  ARE  CRITICAL  TO  SAFE  OPERATION.  RE-
PLACE  THESE  COMPONENTS  WITH  SONY  PARTS  WHOSE

IN  SUPPLEMENTS  PUBLISHED  BY  SONY.
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 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.
CAUTION:
The use of optical instrument with this product will increase eye 
hazard.
CAUTION
Use  of  controls  or  adjustments  or  performance  of  procedures 
other than those specified herein may result in hazardous radia-
tion exposure.
