General Guidelines

An Insulation Transformer should always be used during the servicing of a receiver whose chassis is not insulated from the AC power line. Use a transformer with adequate power rating as its 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, insulation 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 high-voltage 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 it, 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 insulation 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, (30° ~ 40°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 much as possible the original PbF solder 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. (Example : Digital Board)

SAFETY PRECAUTIONS

General Guide Lines

1. It is advisable to insert an insulation transformer in the AC supply before servicing this hot chassis.

2. When servicing, observe the original lead dress, especially the lead dress in the high voltage circuits. If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit.

3. Af ter servicing, see to it that all the protective devices such as insulation barriers, insulation papers, shields and insulation R-C combinations, are properly installed.

4. When the receiver is not to be used for a long period of time, unplug the power cord from the AC cord outlet.

5. Potential, as high as 29.0kV is present when this receiver is in operation. Operation of the receiver without the rear cover involves the danger of a shock hazard from the receiver power supply . Servicing should not be attempted by anyone who is not thoroughly familiar with the precautions necessary when working on high voltage equipment. Always discharge the anode of the picture tube to the receiver chassis before handling the tube. After servicing make the following leakage current checks to prevent the customer from being exposed to shock hazards.

Leakage Current Cold Check

1. Unplug the AC cord and connect a jumper between the two prongs on the plug.

2. Turn on the receiver’s power switch. Measure the resistance value, with an ohmmeter , between the jumper AC plug and each exposed metallic cabinet part on the receiver, such as screw heads, aerials, connectors, control shaft s, etc.When the exposed met allic part has a return path to the chassis, the reading should be between 4M Ω. and 20M Ω. When the exposed metal does not have a return path to the chassis, the reading must be infinite.

Leakage Current Hot Check (Fig. 1)

1. Plug the AC cord directly into the AC outlet. Do not use an insulation transformer for this check.

2. Use a non inductive 2KΩ 10W resistor in series with an exposed metallic part of the receiver and earth such as a water pipe.

3. Using a high impendance AC voltimeter , check the resistor’s potential.

4. Check each met allic part of the receiver .

5. Invert the plug of the AC chord and repeat all measurements .

6. The voltage from any point should not exceed 1.0V

. In case of a measurement is outside of these limits specified,

RMS

there is a possibility of a shock hazard and the receiver should be repaired and rechecked before it is returned to the customer.

X-Radiation

Warning:

The potential sources of X-Radiation in TV set are the EHT section and the picture tube. When using a picture tube test jig for service, ensure that jig is capable of handling 29.0kV without causing X-Radiation.

Note: It is important to use an accurate periodically calibrated high voltage meter .

1. Set the brightness to minimum.

2. Use the remocon to get into Service Mode.

3. Measure the EHT. The meter reading should indicate 27.5±1.5kV. If the meter indication is out of tolerance, immediate service and correction is required to prevent the possibility of premature component failure.

4. To prevent the possibility X-Radiation, it is essential to use the specified picture tube, if service replacement becomes necessary.
