IMPORTANT SAFETY PRECAUTIONS

Prior to shipment from the fact ory, our products are stri ctly insp ected for recogni zed pr oduct sa fety and elec trical codes of the countries in which they are to be sold. Howev er, in order to ma intain such c ompliance, it is equally important to implement the following precautions when a set is being serviced.
Safety Precautions for TV Circuit
1. Before returning an instrum ent t o the c ustom -
er, 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 protec tive devic es are de -
fective and have b een defeated during servicing. (1) Protective shields are provided on this chassis to protect both the technician an d the customer. Correctly replace all missing protective shields, in­cluding any removed for servicing convenience. (2) When reinstalli ng the c hassis an d/or othe r as­sembly in the cabinet, be sure to put back in place all protective de vices, in cluding but not li mited to, nonmetallic control knobs, insulating fishpapers, adjustment and compartment cove rs/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 acr oss the two AC plug prongs. Place the instrument AC switch in the o n position. Connect one lead of an oh mmeter to the A C plug prongs tied together and to uch the other ohmme ­ter 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 mego hm or greater than 5 .2 mego­hm, an abnormality exists that must be corrected before the instrument is r eturne d to the cu stomer . Repeat this test with the ins trument 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 d uring thi s test.) Use a leak-
age current tester or a me tering syst em that com ­plies with American National Standards Institute (ANSI) C101.1 Leakage Current for Appliances and Underwriters Laborat ories (UL) 1410, (50.7). With the instrument AC switc h first in the on posi ­tion and then in the o ff position, measure from a known earth ground (metal water pipe, conduit, etc.) to all exposed metal parts of the instrument (antennas, handle br ackets, metal cabi net, screw heads, metallic overlay s, control shafts, etc.), es ­pecially any exposed metal parts that offer an elec­trical return path to the chassis. Any current measured must not excee d 0.5 milli-ampere. Re ­verse 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 AC CES SORI ES.
e. X-Radiation and High Voltage Limits - Because
the picture tube i s the prim ary potentia l source of X-radiatio n in solid- state TV receiver s, it is s pecial­ly constructed to prohibit X-radiation emissions. For continued X-radiation pr otection, 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 mea su re d ea ch tim e s er vic -

ing is performed that inv olves B+, horizontal de­flection or high voltage. Correct operation of the X­radiation protection circuits also must be recon­firmed each time they are serviced. (X-radiation protection circuits also may be called "horiz ontal disable" or "hold do wn.") R ead a nd a ppl y th e hi gh voltage limits a nd, if the chassis is so e quipped, the X-radiation protection circuit specifications giv­en on instrument labe ls and i n the P roduct S afety & X-Radiation Warning note on the service data chassis schematic. High voltage is maintained within specified limits by close tolerance safety-re­lated components/adjus tme nts in th e hig h-vo lta ge 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 th e receiver cabi net, 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 modificatio ns and the ad­dition of items such as auxiliary audio and/or video output connections, mig ht alter the safety ch arac­teristics of this receiver and create a hazard to the user. Any design alter ations or addition s will void the manufacturer's warr anty 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 pic ture tube only with one of the same type numbe r. Do not rem ove, install , or otherwise handle the picture tube in any ma nner without first putting on shatterproof goggles equipped with side shields. People not so equipped must be ke pt safely away while p icture tubes are handled. Keep the picture tube away from your body. Do not handl e the pictur e tu be b y its neck. Some "in-line" picture tubes are equipped with a permanently at tached 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 conduc tor of th e AC powe r cor d and maybe safety-serviced without an isolation transformer only i f the AC power plug i s inserted so that the chassis is connected to the ground side of the AC power source. To confi rm that the AC power plug is ins erted 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 ch assis 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 so urce , for both pers onnel and test equipment protection.
c. Some TV receiver chassis have a secondary
ground system in addition to the main chassis ground. This se conda ry gro und s ystem is no t iso ­lated 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 wir ing. Always insp ect in all ar eas for pinched, out of plac e, or frayed wiring. C heck 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 origin al specifications. Additiona lly, determine the cause of ov erheating and/or dam­age and, if nece ss ar y, ta ke corre ct i ve ac ti o n to re­move any potential safety hazard.
8. Product Safety Notice - Some electrical and me­chanical parts have s pecia l safety- relat ed char ac­teristics which are often not evident from visual inspection, nor can the protection they give neces­sarily be obtained by replaci ng 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 sh ock, fire, and/or other hazards. The product's safety is under re­view continuously and new instructions are issued whenever appropriate . Prior to shi pment from the factory, our products are strictly inspected to con­firm they comply with the recognized product safe­ty and electrical codes of the countries in which they are to be sold. Howev er, in orde r to mai ntain such compliance , it is equally i mportant to imple ­ment the following precautions when a set is being serviced.
2-2 L6115IMP
Precautions during Servicing
A. Parts identified b y the ( # ) symbo l are c ritica l for
safety. Replace only with part number specified.
B. In addition to safety, othe r parts and assemblies
are specified for conformance with regulations ap­plying to spurious radiati on. 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 abo ut the terminals before so lder­ing.
F. Observe that the wires do not contact heat produc-
ing parts (heatsinks, oxide metal film resistors, fus­ible resistor s, 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
The power transform er uses crimp type connec-
tors which connect the power cord and the primary
side of the transformer. When replacing the trans-
former, follow these step s carefully and precis ely
to prevent shock hazards.
Replacement procedure
1) Remove the old conn ector by c utting the wire s at
a point close to the connector.
Important: Do not re-use a connector (discard it).
2) Strip about 15 mm of the ins ulation 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 con nected. In­sert the wires fully into the connector.
4) Use the crimping tool to crim p the met al sleeve at the center position . Be sure to crimp fully to the complete closure of the tool.
L. When connecting or disconnecting the internal
connectors, first, discon nect the AC plug from the AC supply outlet.
