IMPOTANT SAFETY NOTICEMany electrical and mechanical parts in this chassis have special safety-related characteristics.These parts areidentified by in the Schematic Diagram and Replacement parts List.It is essential that these special safety parts’should be replaced with the same components as recommended inthis manual to prevent X-RADIATION,Shock,Fire,or other Hazards.Do not modify the original design without permission of manufacturer.

SAFETY PRECAUTIONS

General Guidance

An lsolation Transformer should always be used duringthe servicing of a receiver whose chassis is not isolatedfrom the AC power line. Use a transformer of adequatepower rating as this protects the technician from accidentsresulting in personal injury from electrical shocks.

It will also protect the receiver and it’s components frombeing damaged by accidental shorts of the circuitary thatmay be inadvertently introduced during the serviceoperation.If any fuse (or Fusible Resistor) in this TV receiver is blown,replace it with the specified.When replacing a high wattage resistor (Oxide Metal FilmResistor,over 1w),keep the resistor 10mm away from PCB.Keep wires away from high voltage or high temperatureparts.Due to high vacuum and large surface area of picture tube,extreme care should be used in handling the picture Tube.Do not lift the picture tube by it’s Neck.x-RAY RadiationWarning:

The source of X-RAY RASIATION in this TV receiver is theHigh Voltage section and the picture Tube.For continude S-RAY RADIATIONprotection , thereplacement tube must be the same type tube as speci-fied in the Replacement parts List

To determine the presence of high voltage,use an accu-rate high impedance HV meter.Adjust brightness, color,contrast controls to minimum.Measure the high voltage.The meter reading should indicate 23.5+1.5KV:14-19 inch,26 +1.5kv:19-21inch,lf the meter indication is out oftolerance,immediate serviceand correction is required toprevent the possibility of premature component failure.

Before returning the receiver to the customeralways perform an AC leakag current check on theexposed metallic parts of the cabinet,such as antennas,terminals,etc;to be sure the set is safe to operatewithout damage of electrical shock.

Leakage current cold check (Antenna cold check )with the instrument AC plug renoved fron AC source,connect an electical junper across the two AC plug prongs.Place the AC switch in the on position, connect one lead ofohm-meter to the Ac plug prongs tied together and touchother ohm-meter lead in tum to each exposed metallic partssuch as antenna terminals,phone jacks,etc.If the exposed metallic part has a return path to the chassis,

the measured resistance should be beween1MΩ and 5.

2MΩ When the exposed metal has no return path to thechassis the reading must be infinite,An other abnormalityexists that must be corrected before the receiver is returnedto the customer.Leakage Current Hot Check(See below Figure)plug the AC cord DIRECTLY into the AC outlet.Do notuse a line lsolation Transformer during this check.Connect 1.5k/10watt resistor in parallel with a 0.15uFcapacitor between a known good earth ground (Water pipe,Conduit,etc.)and the exposed metallic parts.Measure the AC voltage across the resistor using ACvoltemeter with 1000 ohms/volt or more sensitivity.Reverse plug the AC cord into the AC outlet and repeat ACvoltage measurements for each exposed metallic part.Anyvoltage measured must not exceed 0.75 volt RMS whichis corresponds to 0.5mA.In case any measurement is out of the limits specified,there is possibility of shock hazard and the set must bechecked and repaired before it is retumed to the customer.

Remember:Safety First.General Servicing precautions1.Always unplg the receiver AC power cord from the ACpower source before: a.Removing or reinstalling any component,circuit board module or any other receiver assembly. b.Disconnecting or reconnecting any receiver electrical plug or other electrical connection. c.Connecting a test substitute in parallel with an electro lytic capacitor in the receiver. CAUTION: A wrong part substitution or incorrect polarigy installation of electroiytic capacitors may result in an expiosison hazard. d. Discharging the picture tube anode.2. Test high voltage only by measuring it with an appropri ate high voltage meter or other voltage measuring de vice (DVM,FETVOM,etc)equipped with a suitable high voltage probe. Do not test high voltage by “drawing an arc”.3. Discharge the picture tube anode only by (a)first con necting one end of an insulated clip lead to the degauss ing or kine aquadag grounding system shield at the point where the picture tube socket ground lead is connected, and then (b)otuch the other end of the insulated dip lead to the picture tube anode button, using an insulating handie to avoid personal contact with high voltage.4. Do not spray chemicals on or near this receiver or any of its assemblies.5. Unless specified otherwise in this service manual,clean electrical contacts only by applying the following mixture to the contacts with a pipe cleaner,cotton-topped stick or comparable nonabrasive applicator:10%(by volume) Acetone and 90%(by volume)isopropyl alcohol(90%-90% strength)CAUTION:This is a flammable mixture. Uniess specified otherwise in this service manual,lubri cation of contacts in not require6. Do not defeat any plug/socket B+voltage interlocks with which receivers covered by this service manual might be equipped.7.Do not apply AC power to this instrument and/or any of its electrical assemblies unless all solid-state device heat sinks are correctly installed.8.Always connect the test receiver ground lead to the re ceiver chassis ground before connecting the test receiver positive lead.Always remove the test receiver ground lead last.9.Use with this receiver only the test fixtures specified in this service manusl.CAITION:Do not connect the test fixture ground strap toany heatsink in this receiver.Electrostatically Sensitive(ES)Devicessome semiconductor(solid state)devices can be damaged

SERVICING PRECAUTIONS

easily called Electrostatically Sensitive(ES)Devices.Ex-amples of typical ES devices are integrated circuits andsome field effect traansistors and semicounductor“chip”components.The following techniques should be usedto help reduce the incidence of component damage causedby static by static electricity. 1.lmmediately before handing any semiconductor com-ponent or semiconducotr-equipped assembly.drain off anyelectostatic charge on your body by touching a known earthground.Alematively.

Obtain and wear a commercially available dischargingwrisl strap device.which should be removed to prevent po-tential shock reasons prior to applying power to the unitunder test.

2.After removing an electrical assembly epuipped withESdevice.place the assembly on a conductive surtace suchas aluminum foil.to prevent electrostatic charge buildup orexposure of the assembly.

3.Use only a grounded-tip soldering iron to solder orunsolder ES devices.

4.Use only an anti-static type solder removal device.Some solder removal devices not classified as “anti-static”can generate electrecal charges sufficent to demageES devices.

5.Do not use freon-propelled chemicals.These can gen-erate electrical charges srffient to damage ES devices.

6.Do not remove a repalcement ES device from its pro-tective package until immediately before you are ready toinstall it.(Most replacement ES devices are package withleads electricall shorted together by conductive foam,aluminumfoil or comparable conductive material).

7.lmmediately befor removing the protective materialfrom the ieads of a replacement ES device touch the pro-tective material to the chassis or circuit assembly into whichthe device will be installed.

CAUTION:Be sure no power is applied to the chassis orcircuit and observe all other safety precautions.8.Minmize bodily motions when handling unpackagedreplacement ES devices.(Otherwise harmless motion

such as the bruching together of your clothes fabric or thelifting of your foot from a carpeted floor can generate staticelectricity sufficient to damage an ES device.)General Soldering Guidelines

1.Use a grounded-tip.low-wattage soldering iron andappropriate tip size and shape that will maintan tiptemperture withen the range or 500k to 600k.

2.Use an appropriate gauge of RMA resin-core soldercomposed of 60parts tin/40parts lead.

3.Keep the soldering iron tip clean and well tinned.4.Thorohly clean the surfaces to be soldered Use a mall

wirebristle(0.5inch.or 1.25cm)brush with a metal handle.Do not use freon- propelled spray-on cleaners.5.Use the following unsoldering techniquea.Allow the soldering iron tip to reach normal temperature (500k to 600k)b.Heat the component lead until tne solder melts.c.Quickly draw the melted solder with an anti-statlc,suc tion-

type solder removal device or with solder braid.CAUTION:Work quickly to aviod overheating thecircuiboard printed foill.6.Use the following soldering technique.a.Allow the soldering iron tip to reach a normal temperature(500k to 600k)b.First,hold the soldering iron tip and solder the strand. Against the component lead the solder melts.C.Quickly move the soldering iron tip to the junction of the compontent lead and the printed circuit foil and hold it there oniy until the solder flows onto and around both the component lead and the foil.CAUTION:work quickly to avoid overheating the circuitboard printed foil.d.Closely inspect the solder area and remove any excessor splashed solder with a small wire-bristle brush.IC Remove/ReplacementSome chassis circuit boards have slotted holes (oblong)through wheic the IC leads are inserted’and then bent ftatagainst the circuit foil. When holes are the slotted type thefollowing technique should be used to remove and replacethe IC. When working with boards using the familiar roundhole use the standard technique as outlined in parapraphs5 and 6 above.Removal1. Desolder and straighten each IC lead in one operation by gently prying up on the tead with soldering iron tip as the solder melts.2.Draw away the melted solder with an anti-static suction- type solder removal device (or with solder braid) before removing the IC.Replacement1.Carefully insert the replacement IC in the circuit board2.Carefully bend each IC lead against the circuit foil pad and solder it.3.Clean the soldered areas with a small wire-bristle brudh. (It is not necessary to reapply acrylic coating to the areas). “Small-Signal” Discrete TransistorRemoval/Replacement1.Remove the defective transistor by clipping its leads as close as possible to the component body.2.Bend into a “u” shape the end of each of three leads renaining on the circuit board.3.Bend into a “u” shape the replacement transistor leads.4.Connect the replacement transistor leads to the corre sponding leads extending from the circuit board and crimp the “u”with long nose pliers to insure metal to metal to metal contacttehn solder each connection.Power Output, Transistor DeviceRemoval/Replacement1.Heat and remove al solder from around the transistor leads.2.Remove the heatsink mounting screw (if so equipped).3.Carefully remove the transistor from the heat sink of the circuit board.4.Insert new transistor in the circuit board.5.Solder each transistor lead and clip off excess lead.6.Replace heatsink.Diode Removal/Replacement1.remove defective diode by clipping its leads as close as possible to diode body.

2.Bend the two remaining leads perpendiculay to the cir cuit board.3.Observing diode polarity wrap each lead of the new diodearound the corresponding lead on the circuit board.4.Secruely crimp each connection and solder it.5.Inspect (on the circuit board copper side)the solder joints of the two “original” leads. If they are not shiny reheat them and if necessary apply additional solder.

Fuse and Conventional ResistorRemoval/Replacement1.Clip each fuse or resistor lead at top of the circuit board hollow stake.2.Securely crimp the leads of replacement component around notch at stak top.3.Solder the commections.CAUTION:Maintain original spacing between the replacedcomponent and adjacent component and the circuit boardto prevent excessive component temperaures.Circuit Board Foil REPAIRExcessive heat applied to the copper foil of any printedcircuit board will weaken the adhesive that bonds the foilto the circuit board causing the foil to separte fron or “lift-off” the board. The following guidelines and proceduresshould be followed whenever this condition is encountered.At IC ConnectionsTo repair a defective copper pattem at IC connections usethe following procedure to install a jumper wire on the cop-per pattem side lf the circuit board.9 (use this techniqueony on IC connections)1.Carefully remove the damaged copper pattem with a sharp knife.(Remove only as much copper as absolutely necessary).2.Carefully scratch away the solder resist and acrylic coating(if used) from the end of the remaining copper patten.3. Bend a small “U” in one end of a small gauge jumper wire and carefully crimp it around the IC pin.Solder the IC connection.4.Route the jumper wire along the path of the out-away copper patten and let it overlap the previously scraped end of the good copper pattem.Solder the overlapped area and dip off any excess jumper wire.

At Other ConnectionsUse the following technique to repir the defective copperpattem at connections other than IC pins.This techniqueinvoloves the installation of a jumper wire on the compo-nent side of the circuit board.1.Remove the defective copper pattem with a sharp knife. Remove at least 1/4 inch of copper,to ensure that a haz ardous condition will not exist if the jumper wire opens.2.Trace along the copper pattem from both sides of the pattem break and locate the nearest component that is directly connected to the affected copper pattem.3. Connect insulated 20-gauge jumper wire from the lead of nearest the nearest component on one side of the pattem break to the lead of the nearest component.on the other side,Carefully crimp and solder the connections.CAUTION:Be sure the insulated jumper wire is dressedso the it does ot touch componets or sharp edges.
