3-2 Alignment and Adjustment

3-2-1 General Alignment Instructions

1. Usually, a color TV needs only slight touch-up adjustment upon installation. Checkthe basic characteristics such as picture height,focus and a horizontal and vertical sync.

2. Observe the picture and check for good backand white details. There should be no objectionable color shading: If color shading ispresent, demagnetize the receiver. If colorshading persists, perform purity andconvergence adjustments described below.

3. To protect against shock hazard, use anisolation transformer.

3-2-2 Power Supply Check

Check the following:A: Power plug is connected; “Stand-by” mode B: Power On when “Power ON” button is pressed C: Power On by FBT Each supply is marked on

its lead-in wire. ( )

3-2-3 Focus Adjustment

Adjust the focus control on the FBT for welldefined scanning lines.

3-2-4 Fail Safe Circuit Check (FS) (OPTION)

1. The failsafe check must be the final step in servicing.

2. Turn the power switch ON and adjustcustomer controls for normal operation.

3. Temporarily short pin X to pin R on the mainboard (RX06, RX04) with a jumper wire.Raster will disappear.

4. The TV must remain in this state even afterremoving the jumper wire. This shows thatthe failsafe circuit is working properly.

5. To recover picture and sound, temporarilyturn off the TV and allow the failsafe circuitmore than 30 seconds to reset. Then switchpower ON to produce normal picture andsound.

3-2-5 IC902 Replacement

1. When IC902 is replaced, all values are reset to “Initialized MICOM Data” and readjustmentis necessary.

2. Press the POWER button 10 seconds afterplug-in.

3. To enter the Service Mode, refer to Fig. 3-1(Service Mode Adjustment).

3-2-6 PIF VCO Adjustment

1. Use a Pattern Generator or an off-air signal.

2. Open pin 11 of Micom (IC901) or one side oflead pin for R237.

3. Adjust VCO in the service mode to set IC101Pin 44 (AFT) to 2.5V ± 0.4V.

4. Connect the opened site.

3-2-7 RF-AGC Adjustment

1. Input a PHILLIPS pattern.

2. Set the input signal to 60 dB.

3. Enter into the AGC in the service mode.

4. Adjust AGC until color bar noise disappears.

3-2-8 Sub-Contrast Adjustment

1. Input a gray scale pattern. Use a pattern generator (PM5518).

2. Short D208 to switch off the ABL feed-back.

3. Check CN201 R-OUT with an oscilloscope.

4. Set RC, BC, GC data to 0 in the Service Mode.

5. Adjust SCT to 2.40 ± 0.1Vp-p

6. Remove the short across D208 and restoreABL.

3-2-9 Sub-Tint Adjustment

1. Input a rainbow pattern.

2. Check CN201 B-OUT with an oscilloscope.

3. Adjust STT in the service mode until the 6thpeak is the highest and the 5th and 7th peakshave equal heights.

3-2-10 Sub-Color Adjustment

1. Do sub-color adjustment after the Sub-Contrast and Sub-Tint adjustments.

2. D208 should still be shorted. The ABL shouldstill be switched OFF.

3. Input a color bar pattern. Use a pattern gen-erator (PM5518).

4. Check CN201 R-OUT (use an oscilloscope).

5. Ensure that the RC, GC and BC data are 0.BG are 140 and GG should be 90.

6. Adjust SCR to 2.4 ± 0.1Vp-p (black and red levels).

7. Remove the short across D208 and restoreABL.

1. Precautions

1-1 Safety Precautions

1. Be sure that all of the built-in protectivedevices are replaced. Restore any missingprotective shields.

2. When reinstalling the chassis and its assemblies, be sure to restore all protectivedevices, including: nonmetallic control knobsand compartment covers.

3. Make sure that there are no cabinet openingsthrough which people—particularly children—might insert fingers and contactdangerous voltages. Such openings includethe spacing between the picture tube and thecabinet mask, excessively wide cabinetventilation slots, and improperly fitted back

covers.

If the measured resistance is less than 1.0megohm or greater than 5.2 megohms, anabnormality exists that must be correctedbefore the unit is returned to the customer.

4. Leakage Current Hot Check (Figure 1-1):Warning: Do not use an isolation transformer during this test. Use a leakage-current tester or a metering system that complies with American National StandardsInstitute (ANIS C101.1, Leakage Current forAppliances), and Underwriters Laboratories(UL Publication UL1410, 59.7).

5. With the unit completely reassembled, plugthe AC line cord directly into the power outlet. With the unit’s AC switch first in theON position and then OFF, measure the current between a known earth ground (metalwater pipe, conduit, etc.) and all exposedmetal parts, including: antennas, handlebrackets, metal cabinets, screwheads and control shafts. The current measured shouldnot exceed 0.5 milliamp. Reverse the power-plug prongs in the AC outlet and repeat thetest.

Fig. 1-1 AC Leakage Test

6. Antenna Cold Check: With the unit’s AC plug disconnected from theAC source, connect an electrical jumper acrossthe two AC prongs. Connect one lead of theohmmeter to an AC prong. Connect the otherlead to the coaxial connector.

7. X-ray Limits:The picture tube is especially designed to pro-hibit X-ray emissions. To ensure continued X-ray protection, replace the picture tube onlywith one that is the same type as the original.Carefully reinstall the picture tube shields andmounting hardware; these also provide X-rayprotection.

8. High Voltage Limits:High voltage must be measured each time ser-vicing is done on the B+, horizontal deflectionor high voltage circuits. Correct operation ofthe X-ray protection circuits must be reconfirmed whenever they are serviced.(X-ray protection circuits also may be called

“horizontal disable” or “hold-down”.)

Heed the high voltage limits. These includethe X–ray Protection Specifications Label, andthe Product Safety and X-ray Warning Note onthe service data schematic.

1-1 Safety Precautions (Continued)

9. High voltage is maintained within specifiedlimits by close-tolerance, safety-related components and adjustments. If the high voltage exceeds the specified limits, checkeach of the special components.

10. Design Alteration Warning:Never alter or add to the mechanical or electrical design of this unit. Example: Do notadd auxiliary audio or video connectors. Suchalterations might create a safety hazard. Also,any design changes or additions will void themanufacturer’s warranty.

11. Hot Chassis Warning:Some TV receiver chassis are electrically connected directly to one conductor of the ACpower cord. If an isolation transformer is notused, these units may be safely serviced onlyif the AC power plug is inserted so that thechassis is connected to the ground side of theAC source.

To confirm that the AC power plug is inserted correctly, do the following: Using an AC voltmeter, measure the voltage between the chassis and a known earth ground. If the reading is greater than 1.0V, remove the ACpower plug, reverse its polarity and reinsert.Re-measure the voltage between the chassisand ground.

12. Some TV chassis are designed to operate with85 volts AC between chassis and ground,regardless of the AC plug polarity. These unitscan be safely serviced only if an isolationtransformer inserted between the receiver andthe power source.

13. Some TV chassis have a secondary groundsystem in addition to the main chassis ground.This secondary ground system is not isolated from the AC power line. The twoground systems are electrically separated byinsulating material that must not be defeatedor altered.

14. Components, parts and wiring that appear tohave overheated or that are otherwise damaged should be replaced with parts thatmeet the original specifications. Always determine the cause of damage or overheat-ing, and correct any potential hazards.

15. Observe the original lead dress, especiallynear the following areas: Antenna wiring,sharp edges, and especially the AC and highvoltage power supplies. Always inspect forpinched, out-of-place, or frayed wiring. Donot change the spacing between componentsand the printed circuit board. Check the ACpower cord for damage. Make sure that leadsand components do not touch thermally hotparts.

16. Picture Tube Implosion Warning:The picture tube in this receiver employs“integral implosion” protection. To ensurecontinued implosion protection, make surethat the replacement picture tube is the sameas the original.

17. Do not remove, install or handle the picturetube without first putting on shatterproofgoggles equipped with side shields. Neverhandle the picture tube by its neck. Some “in-line” picture tubes are equipped with a permanently attached deflection yoke; do nottry to remove such “permanently attached”yokes from the picture tube.

18. Product Safety Notice: Some electrical and mechanical parts havespecial safety-related characteristics whichmight not be obvious from visual inspection.These safety features and the protection theygive might be lost if the replacement compo-nent differs from the original—even if thereplacement is rated for higher voltage,wattage, etc.

Components that are critical for safety areindicated in the circuit diagram by shading, ( ) or ( ).

Use replacement components that have thesame ratings, especially for flame resistanceand dielectric strength specifications. A replacement part that does not have thesame safety characteristics as the originalmight create shock, fire or other hazards.

1-2 Servicing Precautions

1. Servicing precautions are printed on the cabinet. Follow them.

2. Always unplug the unit’s AC power cord fromthe AC power source before attempting to: (a)Remove or reinstall any component or assembly, (b) Disconnect an electrical plug orconnector, (c) Connect a test component inparallel with an electrolytic capacitor.

3. Some components are raised above the printedcircuit board for safety. An insulation tube ortape is sometimes used. The internal wiring issometimes clamped to prevent contact withthermally hot components. Reinstall all suchelements to their original position.

4. After servicing, always check that the screws,components and wiring have been correctlyreinstalled. Make sure that the portion aroundthe serviced part has not been damaged.

5. Check the insulation between the blades of theAC plug and accessible conductive parts(examples: metal panels, input terminals andearphone jacks).

6. Insulation Checking Procedure: Disconnect thepower cord from the AC source and turn thepower switch ON. Connect an insulationresistance meter (500V) to the blades of the ACplug.

The insulation resistance between each bladeof the AC plug and accessible conductive parts(see above) should be greater than 1 megohm.

7. Never defeat any of the B+ voltage interlocks.Do not apply AC power to the unit (or any ofits assemblies) unless all solid-state heat sinksare correctly installed.

8. Always connect a test instrument’s groundlead to the instrument chassis ground beforeconnecting the positive lead; always removethe instrument’s ground lead last.

9. When some parts inside the optical engine(except lamp) are damaged, replace the wholeoptical engine.

Precautions

1-3

Warning 1 : First read the “Safety Precautions” section of this manual. If some unforeseen circumstance creates a conflict between the servicing and safety precautions, always follow the safety precautions.

Warning 2 : An electrolytic capacitor installed with the wrong polarity might explode.

1-3 Precautions for Electrostatically Sensitive Devices (ESDs)

1. Some semiconductor (“solid state”) devicesare easily damaged by static electricity. Suchcomponents are called ElectrostaticallySensitive Devices (ESDs); examples includeintegrated circuits and some field-effect transistors. The following techniques willreduce the occurrence of component damagecaused by static electricity.

2. Immediately before handling any semiconductor components or assemblies, drain theelectrostatic charge from your body by touching a known earth ground. Alternatively,wear a discharging wrist-strap device. (Besure to remove it prior to applying power—this is an electric shock precaution.)

3. After removing an ESD-equipped assembly,place it on a conductive surface such as aluminum foil to prevent accumulation ofelectrostatic charge.

4. Do not use freon-propelled chemicals. Thesecan generate electrical charges that damageESDs.

5. Use only a grounded-tip soldering iron whensoldering or unsoldering ESDs.

6. Use only an anti-static solder removal device.Many solder removal devices are not rated as“anti-static”; these can accumulate sufficientelectrical charge to damage ESDs.

7. Do not remove a replacement ESD from itsprotective package until you are ready toinstall it. Most replacement ESDs are packaged with leads that are electrically shorted together by conductive foam, aluminum foil or other conductive materials.

8. Immediately before removing the protectivematerial from the leads of a replacement ESD,touch the protective material to the chassis orcircuit assembly into which the device will beinstalled.

9. Minimize body motions when handlingunpackaged replacement ESDs. Motions suchas brushing clothes together, or lifting a footfrom a carpeted floor can generate enough static electricity to damage an ESD.

Precautions
