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 ade uate 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 fami-
liar with the necessary precautions when servicing high-voltage e uipment.
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 s . 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
shieldinf 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 operatore.
Do not use a line isolation transformer when testing.
Important Sa ety Notice
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 whit the manufacturers specified replacement
parts to prevent X-ray radiation, shock, fire or other hazards. Do not modify the original design whitout manufacturers permission.
Warning !
It is essential that these critical parts are replaced with
the manufacturers specified replacement parts to pre-
vent X-ray radiation, shock, fire or other hazards.

ABOUT LEAD FREE SOLDER (PbF)
This model uses lead free solder (PbF).
CAUTION:
•Pbfreesolderhasahighermeltingpointthanstandardsolder;typicallythmeltingpointis50
- 70°F (300 - 400°C) higher. Please use a high temperature soldering iron. In case of the
solderingiron withtemperature control,please set it to700 ±20°F (370 ±10°C).
• Pb free solder will tend to splash when heated too high (about 1100°F/ 600°C).
When soldering or unsoldering, please completely remove all of the solder on the pins or
solder area, and be sure to heat the soldering points with the Pb free solder until it melts
enough.
