IMPORTANT SAFETY PRECAUTIONS
Prior to shipment from the factory, our products are strictly inspected for recognized product safety and electrical codes of the countries in which they are to be sold. However, in order to maintain such compliance, it is equally important to implement the following precautions when a set is being serviced.
Safety Precautions for TV Circuit
1. Before returning an instrument to the custom­er, always make a safety check of the entire instru-
ment, including, but not limited to, the following items:
a. Be sure that no built-in protective devices are de-
fective and have been defeated during servicing. (1) Protective shields are provided on this chassis to protect both the technician and the customer. Correctly replace all missing protective shields, in­cluding any removed for servicing convenience. (2) When reinstalling the chassis and/or other as­sembly in the cabinet, be sure to put back in place all protective devices, including but not limited to, nonmetallic control knobs, insulating fishpapers, adjustment and compartment covers/shields, and isolation resistor/capacitor networks. Do not oper-
ate this instrument or permit it to be operated without all protective devices correctly in­stalled and functioning. Servicers who defeat safety features or fail to perform safety checks may be liable for any resulting damage.
b. Be sure that there are no cabinet openings through
which an adult or child might be able to insert their fingers and contact a hazardous voltage. Such openings include, but are not limited to, (1) spac­ing between the picture tube and the cabinet mask, (2) excessively wide cabinet ventilation slots, and (3) an improperly fitted and/or incorrectly secured cabinet back cover.
c. Antenna Cold Check - With the instrument AC
plug removed from any AC source, connect an electrical jumper across the two AC plug prongs. Place the instrument AC switch in the on position. Connect one lead of an ohmmeter to the AC plug prongs tied together and touch the other ohmme­ter lead in turn to each tuner antenna input ex­posed terminal screw and, if applicable, to the coaxial connector. If the measured resistance is less than 1.0 megohm or greater than 5.2 mego­hm, an abnormality exists that must be corrected before the instrument is returned to the customer. Repeat this test with the instrument AC switch in the off position.
d. Leakage Current Hot Check - With the instru-
ment completely reassembled, plug the AC line cord directly into a 120V AC outlet. (Do not use an isolation transformer during this test.) Use a leak-
age current tester or a metering system that com­plies with American National Standards Institute (ANSI) C101.1 Leakage Current for Appliances and Underwriters Laboratories (UL) 1410, (50.7). With the instrument AC switch first in the on posi­tion and then in the off position, measure from a known earth ground (metal water pipe, conduit, etc.) to all exposed metal parts of the instrument (antennas, handle brackets, metal cabinet, screw heads, metallic overlays, control shafts, etc.), es­pecially any exposed metal parts that offer an elec­trical return path to the chassis. Any current measured must not exceed 0.5 milli-ampere. Re­verse the instrument power cord plug in the outlet and repeat the test.
ANY MEASUREMENTS NOT WITHIN THE LIMITS SPECIFIED HEREIN INDICATE A POTENTIAL SHOCK HAZARD THAT MUST BE ELIMINATED BEFORE RETURNING THE INSTRUMENT TO THE CUSTOMER OR BEFORE CONNECTING THE ANTENNA OR ACCESSORIES.
e. X-Radiation and High Voltage Limits - Because
the picture tube is the primary potential source of X-radiation in solid-state TV receivers, it is special­ly constructed to prohibit X-radiation emissions. For continued X-radiation protection, the replace­ment picture tube must be the same type as the original. Also, because the picture tube shields and mounting hardware perform an X-radiation protection function, they must be correctly in place. High voltage must be measured each time servic-

ing is performed that involves B+, horizontal de­flection or high voltage. Correct operation of the X-radiation protection circuits also must be recon­firmed each time they are serviced. (X-radiation protection circuits also may be called "horizontal disable" or "hold down.") Read and apply the high voltage limits and, if the chassis is so equipped, the X-radiation protection circuit specifications giv­en on instrument labels and in the Product Safety & X-Radiation Warning note on the service data chassis schematic. High voltage is maintained within specified limits by close tolerance safety-re­lated components/adjustments in the high-voltage circuit. If high voltage exceeds specified limits, check each component specified on the chassis schematic and take corrective action.
2. Read and comply with all caution and safety-relat­ed notes on or inside the receiver cabinet, on the receiver chassis, or on the picture tube.
3. Design Alteration Warning - Do not alter or add to the mechanical or electrical design of this TV re­ceiver. Design alterations and additions, including, but not limited to circuit modifications and the ad­dition of items such as auxiliary audio and/or video output connections, might alter the safety charac­teristics of this receiver and create a hazard to the user. Any design alterations or additions will void the manufacturer's warranty and may make you, the servicer, responsible for personal injury or property damage resulting therefrom.
4. Picture Tube Implosion Protection Warning -
The picture tube in this receiver employs integral implosion protection. For continued implosion pro­tection, replace the picture tube only with one of the same type number. Do not remove, install, or otherwise handle the picture tube in any manner without first putting on shatterproof goggles equipped with side shields. People not so equipped must be kept safely away while picture tubes are handled. Keep the picture tube away from your body. Do not handle the picture tube by its neck. Some "in-line" picture tubes are equipped with a permanently attached deflection yoke; be­cause of potential hazard, do not try to remove such "permanently attached" yokes from the pic­ture tube.
5. Hot Chassis Warning -
a. Some TV receiver chassis are electrically connect-
ed directly to one conductor of the AC power cord and maybe safety-serviced without an isolation transformer only if the AC power plug is inserted so that the chassis is connected to the ground side of the AC power source. To confirm that the AC power plug is inserted correctly, with an AC volt­meter, measure between the chassis and a known
earth ground. If a voltage reading in excess of 1.0V is obtained, remove and reinsert the AC power plug in the opposite polarity and again measure the voltage potential between the chassis and a known earth ground.
b. Some TV receiver chassis normally have 85V
AC(RMS) between chassis and earth ground re­gardless of the AC plug polarity. This chassis can be safety-serviced only with an isolation transform­er inserted in the power line between the receiver and the AC power source, for both personnel and test equipment protection.
c. Some TV receiver chassis have a secondary
ground system in addition to the main chassis ground. This secondary ground system is not iso­lated from the AC power line. The two ground sys­tems are electrically separated by insulation material that must not be defeated or altered.
6. Observe original lead dress. Take extra care to as­sure correct lead dress in the following areas: a. near sharp edges, b. near thermally hot parts-be sure that leads and components do not touch ther­mally hot parts, c. the AC supply, d. high voltage, and e. antenna wiring. Always inspect in all areas for pinched, out of place, or frayed wiring. Check AC power cord for damage.
7. Components, parts, and/or wiring that appear to have overheated or are otherwise damaged should be replaced with components, parts, or wir­ing that meet original specifications. Additionally, determine the cause of overheating and/or dam­age and, if necessary, take corrective action to re­move any potential safety hazard.
8. Product Safety Notice - Some electrical and me­chanical parts have special safety-related charac­teristics which are often not evident from visual inspection, nor can the protection they give neces­sarily be obtained by replacing them with compo­nents rated for higher voltage, wattage, etc.. Parts that have special safety characteristics are identi­fied by a ( ! ) on schematics and in parts lists. Use of a substitute replacement that does not have the same safety characteristics as the recommended replacement part might create shock, fire, and/or other hazards. The Product's Safety is under re­view continuously and new instructions are issued whenever appropriate. Prior to shipment from the factory, our products are strictly inspected to con­firm with the recognized product safety and electri­cal codes of the countries in which they are to be sold. However, in order to maintain such compli­ance, it is equally important to implement the fol­lowing precautions when a set is being serviced.
1-3-3 X5TPSFTY
Precautions during Servicing
A. Parts identified by the ( ! ) symbol are critical for
safety.
Replace only with part number specified.
B. In addition to safety, other parts and assemblies
are specified for conformance with regulations ap­plying to spurious radiation. These must also be re­placed only with specified replacements.
Examples: RF converters, RF cables, noise block­ing capacitors, and noise blocking filters, etc.
C. Use specified internal wiring. Note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
D. Use specified insulating materials for hazardous
live parts. Note especially:
1) Insulation Tape
2) PVC tubing
3) Spacers
4) Insulators for transistors.
E. When replacing AC primary side components
(transformers, power cord, etc.), wrap ends of wires securely about the terminals before solder­ing.
F. Observe that the wires do not contact heat produc-
ing parts (heatsinks, oxide metal film resistors, fus­ible resistors, etc.)
G. Check that replaced wires do not contact sharp
edged or pointed parts.
H. When a power cord has been replaced, check that
5~6 kg of force in any direction will not loosen it.
I. Also check areas surrounding repaired locations.
J. Use care that foreign objects (screws, solder drop-
lets, etc.) do not remain inside the set.
K. Crimp type wire connector
When replacing the power transformer in sets where the connections between the power cord and power transformer primary lead wires are per­formed using crimp type connectors, in order to prevent shock hazards, perform carefully and pre­cisely the following steps.
Replacement procedure
1) Remove the old connector by cutting the wires at a point close to the connector.
Important: Do not re-use a connector (discard it).
2) Strip about 15 mm of the insulation from the ends of the wires. If the wires are stranded, twist the strands to avoid frayed conductors.
3) Align the lengths of the wires to be connected. In­sert the wires fully into the connector.
4) Use the crimping tool to crimp the metal sleeve at the center position. Be sure to crimp fully to the complete closure of the tool.
L. When connecting or disconnecting the VCR con-
nectors, first, disconnect the AC plug from AC sup­ply socket.
1-3-4 X5TPSFTY
Safety Check after Servicing
Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts and wires have been returned to original positions. Afterwards, perform the following tests and confirm the specified values in order to verify compliance with safety standards.
1. Clearance Distance
When replacing primary circuit components, confirm specified clearance distance (d) and (d') between sol­dered terminals, and between terminals and surround­ing metallic parts. (See Fig. 1)
Table 1 : Ratings for selected area
Note: This table is unofficial and for reference only.
Be sure to confirm the precise values.
2. Leakage Current Test
Confirm the specified (or lower) leakage current be­tween B (earth ground, power cord plug prongs) and externally exposed accessible parts (RF terminals, an­tenna terminals, video and audio input and output ter­minals, microphone jacks, earphone jacks, etc.).
Measuring Method : (Power ON)
Insert load Z between B (earth ground, power cord plug prongs) and exposed accessible parts. Use an AC voltmeter to measure across both terminals of load Z. See Fig. 2 and following table.

How to Remove / Install Flat Pack IC
Caution:
1. The Flat Pack-IC shape may differ by models. Use an appropriate hot-air flat pack-IC desoldering ma­chine, whose shape matches that of the Flat Pack­IC.
2. Do not apply the hot air to the chip parts around the
Flat Pack-IC for over 6 seconds as damage may occur to the chip parts. Put Masking Tape around the Flat Pack-IC to protect other parts from dam­age. (Fig. S-1-2)
3. The Flat Pack-IC on the CBA is affixed with glue, so
be careful not to break or damage the foil of each pin or solder lands under the IC when removing it.
1. Removal
With Hot - Air Flat Pack - IC Desoldering Machine:
a. Prepare the Hot - Air Flat Pack - IC Desoldering
Machine, then apply hot air to Flat Pack - IC (about 5~6 seconds). (Fig. S-1-1)
b. Remove the Flat Pack- IC with tweezers while
applying the hot air.
With Soldering Iron:
a. Using desoldering braid, remove the solder from all
pins of the Flat Pack - IC. When you use solder flux which is applied to all pins of the Flat Pack - IC, you can remove it easily. (Fig. S-1-3)
b. Lift each lead of the Flat Pack - IC upward one by
one, using a sharp pin or wire to which solder will not adhere (iron wire). When heating the pins, use a fine tip soldering iron or a hot air Desoldering Machine. (Fig. S-1-4)

b. Affix the wire to a workbench or solid mounting
point, as shown in Fig. S-1-5.
c. Pull up on the wire as the solder melts so as to lift
the IC leads from the CBA contact pads, while heating the pins using a fine tip soldering iron or hot air blower.
Note:
When using a soldering iron, care must be taken to ensure that the Flat Pack - IC is not being held by glue, or when it is removed from the CBA, it may be damaged if force is used.
2. Installation
a. Using desoldering braid, remove the solder from
the foil of each pin of the Flat Pack - IC on the CBA, so you can install a replacement Flat Pack - IC more easily.
b. The "I" mark on the Flat Pack - IC indicates pin 1
(See Fig. S-1-6). Make sure this mark matches the 1 on the CBA when positioning for installation. Then pre - solder the four corners of the Flat Pack­IC (See Fig. S-1-7).
c. Solder all pins of the Flat Pack - IC. Make sure that
none of the pins have solder bridges.

Instructions for Handling Semiconductors
Electrostatic breakdown of the semiconductors may occur due to a potential difference caused by electro­static charge during unpacking or repair work.
Ground for Human Body
Be sure to wear a grounding band (1M) that is prop­erly grounded to remove any static electricity that may be charged on the body.
Ground for Work Bench
Be sure to place a conductive sheet or copper plate with proper grounding (1M) on the work bench or other surface, where the semiconductors are to be placed. Because the static electricity charge on the clothing will not escape through the body grounding band, be careful to avoid contacting semiconductors to clothing.
