Weight
Specifications are subject to change without notice. Weight and dimensions shown are approximate.
Special components are used in this television set which are important for safety. These parts are identified on the schematic
diagram by the symbol . It is essential that these critical parts are replaced with the manufacturer’s specified replacement
parts to prevent X-ray radiation, shock, fire or other hazards. Do not modify the original design without manufacturer’s permission.

General Guidelines
An Isolation Transformer should always be used during the servicing
of a receiver whose chassis is not isolated from the AC power line. Use
a transformer of adequate power rating as this protects the technician
from accidents resulting in personal injury from electrical shocks. It will
also protect the Receiver from being damaged by accidental shorting
that may occur during servicing.
When servicing, observe the original lead dress, especially in the high
voltage circuit. Replace all damaged parts (also parts that show signs
of overheating.)
Always Replace Protective Devices, such as fishpaper, isolation
resistors and capacitors, and shields after servicing the Receiver. Use
only manufacturer’s recommended rating for fuses, circuit breakers,
etc.
High potentials are present when this Receiver is operating. Operation
of the Receiver without the rear cover introduces danger from electrical
shock. Servicing should not be performed by anyone who is not
thoroughly familiar with the necessary precautions when servicing highvoltage equipment.
Extreme care should be practiced when Handling the Picture Tube.
Rough handling may cause it to implode due to atmospheric pressure
(14.7 lbs per sq. in). Do not sick or scratch the glass or subject it to any
undue pressure. When handling, use safety goggles and heavy gloves
for protection. Discharge the picture tube by shorting the anode to
chassis ground (not to the cabinet or to other mounting hardware).
When discharging, connect cold ground (i.e. dag ground lead) to the
anode with a well insulated wire or use a grounding probe.
Avoid prolonged exposure at close range to unshielded areas of the
picture tube to prevent exposure to X-ray radiation.
The Test Picture Tube used for servicing the chassis at the bench
should incorporate safety glass and magnetic shielding. The safety
glass provides shielding for the tube viewing area against X-ray radiation
as well as implosion. The magnetic shield limits X-ray radiation around
the bell of the picture tube in addition to restricting magnetic effects.
When using a picture tube test jig for service, ensure that the jig is
capable of handling 31kV without causing X-ray radiation.
Before returning a serviced receiver to the owner, the service technician
must thoroughly test the unit to ensure that is completely safe to operate.
Do not use a line isolation transformer when testing.
Warning !
It is essential that these critical parts are replaced
with the manufacturer’s specified replacement parts
!
to prevent X-ray radiation, shock, fire or other hazards.

ABOUT LEAD FREE SOLDER (PbF)
Note:
In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to standard solder or solder that
contains lead.
We will use PbF solder when discussing the lead free solder used in our manufacturing process which is made from Tin (Sn),
Silver, (Ag), and Copper, (Cu).
This model, and others like it, manufactured using lead free solder will have PbF stamped on the PCB. For service and repair
work we suggest using the same type of solder although, with some precautions, standard Pb solder can also be used.
Caution
• PbF solder has a melting point that is 50° ~ 70° F, (300° ~ 400°C) higher than Pb solder. Please use a soldering iron with
temperature control and adjust it to 700° ± 20° F, (370° ± 10°C).In case of using high temperature soldering iron, please be
careful not to heat too long.
• PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100°F, (600°C).
• If you must use Pb solder on a PCB manufactured using PbF solder, remove as much of the original PbF solder as possible
and be sure that any remaining is melted prior to applying the Pb solder.
• When applying PbF solder to double layered boards, please check the component side for excess which may flow onto the
opposite side (See figure, below).
SUGGESTED PbF SOLDER
There are several types of PbF solder available commercially. While this product is manufactured using Tin, Silver, and Copper,
(Sn+Ag+Cu), you can also use Tin and Copper, (Sn+Cu), or Tin, Zinc, and Bismuth, (Sn+Zn+Bi). Please check the manufac
turer’s specific instructions for the melting points of their products and any precautions for using their product with other
materials.
The following lead free (PbF) solder wire sizes are recommended for service of this product: 0.3mm, 0.6mm and 1.0mm.
HOW TO RECOGNIZE THAT PB FREE SOLDER IS USED
P.C.Boards marked as “PbF” use Pb Free solder. (See the figure below.) Pb Free is not used the Power Supply Board of this
unit.
