SAFETY PRECAUTIONS 

Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by in the 

Schematic Diagram and Exploded View. 

It is essential that these special safety parts should be replaced with the same components as recommended in this manual to prevent 

Shock, Fire, or other Hazards. 

Do not modify the original design without permission of manufacturer. 

General Guidance 

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 adequate power rating as this 

protects the technician from accidents resulting in personal injury 

from electrical shocks. 

It will also protect the receiver and it's components from being 

damaged by accidental shorts of the circuitry that may be 

inadvertently introduced during the service operation. 

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 Film Resistor, 

over 1W), keep the resistor 10mm away from PCB. 

Keep wires away from high voltage or high temperature parts. 

Before returning the receiver to the customer, 

always perform an AC leakage current check on the exposed 

metallic parts of the cabinet, such as antennas, terminals, etc., to 

be sure the set is safe to operate without damage of electrical 

shock. 

Leakage Current Cold Check(Antenna Cold Check) 

With the instrument AC plug removed from AC source, connect an 

electrical jumper across the two AC plug prongs. Place the AC 

switch in the on position, connect one lead of ohm-meter to the AC 

plug prongs tied together and touch other ohm-meter lead in turn to 

each exposed metallic parts such as antenna terminals, phone 

jacks, etc. 

If the exposed metallic part has a return path to the chassis, the 

measured resistance should be between 1MΩ and 5.2MΩ. 

When the exposed metal has no return path to the chassis the 

reading must be infinite. 

An other abnormality exists that must be corrected before the 

receiver is returned to the customer. 

IMPORTANT SAFETY NOTICE 

- 3 - 

Leakage Current Hot Check (See below Figure) 

Plug the AC cord directly into the AC outlet. 

Do not use a line Isolation Transformer during this check. 

Connect 1.5K/10watt resistor in parallel with a 0.15uF capacitor 

between a known good earth ground (Water Pipe, Conduit, etc.) 

and the exposed metallic parts. 

Measure the AC voltage across the resistor using AC voltmeter 

with 1000 ohms/volt or more sensitivity. 

Reverse plug the AC cord into the AC outlet and repeat AC voltage 

measurements for each exposed metallic part. Any voltage 

measured must not exceed 0.75 volt RMS which is corresponds to 

0.5mA. 

In case any measurement is out of the limits specified, there is 

possibility of shock hazard and the set must be checked and 

repaired before it is returned to the customer.

CAUTION: Before servicing receivers covered by this service 

manual and its supplements and addenda, read and follow the 

SAFETY PRECAUTIONS on page 3 of this publication. 

NOTE: If unforeseen circumstances create conflict between the 

following servicing precautions and any of the safety precautions on 

page 3 of this publication, always follow the safety precautions. 

Remember: Safety First. 

General Servicing Precautions 

1. Always unplug the receiver AC power cord from the AC power 

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 electrolytic 

capacitor in the receiver. 

CAUTION: A wrong part substitution or incorrect polarity 

installation of electrolytic capacitors may result in an 

explosion hazard. 

2. Test high voltage only by measuring it with an appropriate high 

voltage meter or other voltage measuring device (DVM, 

FETVOM, etc) equipped with a suitable high voltage probe. 

Do not test high voltage by "drawing an arc". 

3. Do not spray chemicals on or near this receiver or any of its 

assemblies. 

4. Unless specified otherwise in this service manual, clean 

electrical contacts only by applying the following mixture to the 

contacts with a pipe cleaner, cotton-tipped stick or comparable 

non-abrasive applicator; 10% (by volume) Acetone and 90% (by 

volume) isopropyl alcohol (90%-99% strength) 

CAUTION: This is a flammable mixture. 

Unless specified otherwise in this service manual, lubrication of 

contacts in not required. 

5. Do not defeat any plug/socket B+ voltage interlocks with which 

receivers covered by this service manual might be equipped. 

6. 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. 

7. Always connect the test receiver ground lead to the receiver 

chassis ground before connecting the test receiver positive 

lead. 

Always remove the test receiver ground lead last. 

8. Use with this receiver only the test fixtures specified in this 

service manual. 

CAUTION: Do not connect the test fixture ground strap to any 

heat sink in this receiver. 

Electrostatically Sensitive (ES) Devices 

Some semiconductor (solid-state) devices can be damaged easily 

by static electricity. Such components commonly are called 

Electrostatically Sensitive (ES) Devices. Examples of typical ES 

devices are integrated circuits and some field-effect transistors and 

semiconductor "chip" components. The following techniques 

should be used to help reduce the incidence of component 

damage caused by static by static electricity. 

1. Immediately before handling any semiconductor component or 

semiconductor-equipped assembly, drain off any electrostatic 

charge on your body by touching a known earth ground. 

Alternatively, obtain and wear a commercially available 

discharging wrist strap device, which should be removed to 

prevent potential shock reasons prior to applying power to the 



SERVICING PRECAUTIONS 

- 4 - 

unit under test. 

2. After removing an electrical assembly equipped with ES 

devices, place the assembly on a conductive surface such as 

aluminum foil, to prevent electrostatic charge buildup or 

exposure of the assembly. 

3. Use only a grounded-tip soldering iron to solder or unsolder ES 

devices. 

4. Use only an anti-static type solder removal device. Some solder 

removal devices not classified as "anti-static" can generate 

electrical charges sufficient to damage ES devices. 

5. Do not use freon-propelled chemicals. These can generate 

electrical charges sufficient to damage ES devices. 

6. Do not remove a replacement ES device from its protective 

package until immediately before you are ready to install it. 

(Most replacement ES devices are packaged with leads 

electrically shorted together by conductive foam, aluminum foil 

or comparable conductive material). 

7. Immediately before removing the protective material from the 

leads of a replacement ES device, touch the protective material 

to the chassis or circuit assembly into which the device will be 

installed. 

CAUTION: Be sure no power is applied to the chassis or circuit, 

and observe all other safety precautions. 

8. Minimize bodily motions when handling unpackaged 

replacement ES devices. (Otherwise harmless motion such as 

the brushing together of your clothes fabric or the lifting of your 

foot from a carpeted floor can generate static electricity 

sufficient to damage an ES device.) 

General Soldering Guidelines 

1. Use a grounded-tip, low-wattage soldering iron and appropriate 

tip size and shape that will maintain tip temperature within the 

range or 500°F to 600°F. 

2. Use an appropriate gauge of RMA resin-core solder composed 

of 60 parts tin/40 parts lead. 

3. Keep the soldering iron tip clean and well tinned. 

4. Thoroughly clean the surfaces to be soldered. Use a mall wirebristle 

(0.5 inch, or 1.25cm) brush with a metal handle. 

Do not use freon-propelled spray-on cleaners. 

5. Use the following unsoldering technique 

a. Allow the soldering iron tip to reach normal temperature. 

(500°F to 600°F) 

b. Heat the component lead until the solder melts. 

c. Quickly draw the melted solder with an anti-static, suctiontype 

solder removal device or with solder braid. 

CAUTION: Work quickly to avoid overheating the circuit 

board printed foil. 

6. Use the following soldering technique. 

a. Allow the soldering iron tip to reach a normal temperature 

(500°F to 600°F) 

b. First, hold the soldering iron tip and solder the strand against 

the component lead until the solder melts. 

c. Quickly move the soldering iron tip to the junction of the 

component lead and the printed circuit foil, and hold it there 

only until the solder flows onto and around both the 

component lead and the foil. 

CAUTION: Work quickly to avoid overheating the circuit 

board printed foil. 

d. Closely inspect the solder area and remove any excess or 

splashed solder with a small wire-bristle brush. 


IC Remove/Replacement 

Some chassis circuit boards have slotted holes (oblong) through 

which the IC leads are inserted and then bent flat against the 

circuit foil. When holes are the slotted type, the following technique 

should be used to remove and replace the IC. When working with 

boards using the familiar round hole, use the standard technique 

as outlined in paragraphs 5 and 6 above. 

Removal 

1. Desolder and straighten each IC lead in one operation by gently 

prying up on the lead with the 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. 

Replacement 

1. Carefully insert the replacement IC in the circuit board. 

2. Carefully bend each IC lead against the circuit foil pad and 

solder it. 

3. Clean the soldered areas with a small wire-bristle brush. 

(It is not necessary to reapply acrylic coating to the areas). 

"Small-Signal" Discrete Transistor 

Removal/Replacement 

1. 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 remaining 

on the circuit board. 

3. Bend into a "U" shape the replacement transistor leads. 

4. Connect the replacement transistor leads to the corresponding 

leads extending from the circuit board and crimp the "U" with 

long nose pliers to insure metal to metal contact then solder 

each connection. 

Power Output, Transistor Device 


1. Heat and remove all solder from around the transistor leads. 

2. Remove the heat sink 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 heat sink. 

Diode Removal/Replacement 

1. Remove defective diode by clipping its leads as close as 

possible to diode body. 

2. Bend the two remaining leads perpendicular y to the circuit 

board. 

3. Observing diode polarity, wrap each lead of the new diode 

around the corresponding lead on the circuit board. 

4. Securely 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 Resistor 


1. 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 stake top. 

3. Solder the connections. 

CAUTION: Maintain original spacing between the replaced 

component and adjacent components and the circuit board to 

prevent excessive component temperatures.

Circuit Board Foil Repair 

Excessive heat applied to the copper foil of any printed circuit 

board will weaken the adhesive that bonds the foil to the circuit 

board causing the foil to separate from or "lift-off" the board. The 

following guidelines and procedures should be followed whenever 

this condition is encountered. 

At IC Connections 

To repair a defective copper pattern at IC connections use the 

following procedure to install a jumper wire on the copper pattern 

side of the circuit board. (Use this technique only on IC 

connections). 

1. Carefully remove the damaged copper pattern 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 pattern. 

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 

pattern and let it overlap the previously scraped end of the good 

copper pattern. Solder the overlapped area and clip off any 

excess jumper wire. 

At Other Connections 

Use the following technique to repair the defective copper pattern 

at connections other than IC Pins. This technique involves the 

installation of a jumper wire on the component side of the circuit 

board. 

1. Remove the defective copper pattern with a sharp knife. 

Remove at least 1/4 inch of copper, to ensure that a hazardous 

condition will not exist if the jumper wire opens. 

2. Trace along the copper pattern from both sides of the pattern 

break and locate the nearest component that is directly 

connected to the affected copper pattern. 

3. Connect insulated 20-gauge jumper wire from the lead of the 

nearest component on one side of the pattern 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 dressed so the 

it does not touch components or sharp edges.

5.3. White Balance Adjustment 

(1) Overview 

W/B adj. Objective & How-it-works 

- Objective: To reduce each Panel’s W/B deviation 

- How-it-works: When R/G/B gain in the OSD is at 192, it 

means the panel is at its Full Dynamic 

Range. In order to prevent saturation of 

Full Dynamic range and data, one of 

R/G/B is fixed at 192, and the other two is 

lowered to find the desired value. 

- Adj. condition : normal temperature 

1) Surrounding Temperature: 25±5ºC 

2) Warm-up time: About 5 Min 

3) Surrounding Humidity: 20% ~ 80% 

(2) Equipment 

1) Color Analyzer: CA-210 (NCG: CH 9 / WCG: CH12) 

2) Adj. Computer(During auto adj., RS-232C protocol is 

needed) 

3) Adjust Remocon 

4) Video Signal Generator MSPG-925F 720p/216-Gray

192, and the rest will be lowered to meet the desired 

value. 

5) Adj. is performed in COOL, MEDIUM, WARM 3 modes 

of color temperature. 

- If internal pattern is not available, use RF input. In EZ 

Adj. menu 6.White Balance, you can select one of 2 

Test-pattern: ON, OFF. Default is inner(ON). By 

selecting OFF, you can adjust using RF signal in 216 

Gray pattern.

* Adj. condition and cautionary items 

1) Lighting condition in surrounding area 

Surrounding lighting should be lower 10 lux. Try to 

isolate adj. area into dark surrounding. 

2) Probe location 

- LCD: Color Analyzer (CA-210) probe should be 

within 10cm and perpendicular of the module 

surface (80°~ 100°) 

3) Aging time 

- After Aging Start, Keep the Power ON status during 5 

Minutes. 

- In case of LCD, Back-light on should be checked 

using no signal or Full-white pattern.
