2.1.1. LEAKAGE CURRENT COLDCHECK

1. Unplug the AC cord and connect a jumper between the twoprongs on the plug.

2. Measure the resistance value, with an ohmmeter, betweenthe jumpered AC plug and each exposed metallic cabinetpart on the equipment such as screwheads, connectors,control shafts, etc. When the exposed metallic part has areturn path to thechassis, the reading should be between1MΩ and 5.2MΩ.When the exposed metal does not have a return path to

the chassis, the reading must be .

Figure 1

2.1.2. LEAKAGE CURRENT HOT CHECK(See Figure 1 .)

1. Plug the AC cord directly into the AC outlet. Do not use anisolation transformer for this check.

2. Connect a 1.5kΩ, 10 watts resistor, in parallel with a 0.15µFcapacitors, between each exposed metallic part on the setand a good earth ground such as a water pipe, as shown inFigure 1 .

3. Use an AC voltmeter, with 1000 ohms/volt or moresensitivity, to measure the potential across the resistor.

4. Check each exposed metallic part, and measure thevoltage at each point.

5. Reverse the AC plug in the AC outlet and repeat each of theabove measurements.

6. The potential at any point should not exceed 0.75 voltsRMS. A leakage current tester (Simpson Model 229 orequivalent) may be used to make the hot checks, leakagecurrent must not exceed 1/2 milliamp. In case ameasurement is outsideof the limits specified, there is apossibility of a shock hazard, and the equipment should berepaired and rechecked before it is returned to thecustomer.

2 Safety Precautions2.1. GENERAL GUIDELINES 1. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or

damaged by the short circuit. 2. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly

installed. 3. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.

3 Prevention of Electro Static Discharge (ESD) toElectrostatically Sensitive (ES) Devices

Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are calledElectrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistorsandsemiconductor «chip» components. The following techniques should be used to help reduce the incidence of component damagecaused by electro static discharge (ESD). 1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on your

body by touching a known earth ground. Alternatively, obtain and wear a commercially available dischargingESD wrist strap,which should be removed for potential shock reasons prior to applying power to the unit under test.

2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such asaluminum 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 solder removal device. Some solder removal devices not classified as «anti-static (ESD protected)» can

generate electrical charge 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 orcomparableconductive material).

7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective materialto the chassis or circuit assembly into which the device will be installed.

5

SA-HT878GC / SA-HT878GCS

CautionBe 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 thebrushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity(ESD)sufficient to damage an ES device).

4 Before Repair and Adjustment (Using Active Subwoofer)Disconnect AC power, discharge Power Supply Capacitors C546~C549 through a 10 Ω, 10 W resistor to ground.DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices.After repairs are completed, restore power gradually using a variac, to avoid overcurrent.Current consumption at AC 110/127/220-230/240 V, 50/60 Hz in NO SIGNAL mode should be ~ 1000 mA.

5 Protection CircuitryThe protection circuitry may have operated if either of the following conditions are noticed: · No sound is heard when the power is turned on. · Sound stops during a performance.

The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative speaker connection wires are“shorted”, or if speaker systems with an impedance less than the indicated rated impedance of the amplifier are used.If this occurs, follow the procedure outlines below: 1. Turn off the power. 2. Determine the cause of the problem and correct it. 3. Turn on the power once again after one minute.Note:When the protection circuitry functions, the unit will not operate unless the power is first turned off and then on again.

6 Precaution of Laser DiodeCAUTION :

This product utilizes a laser. Invisible laser radiation is emitted from the optical pick up lens when the unit is turned on.Wavelength : 662nm(DVD)/785nm(VCD/CD)Maximum output radiation power from pick up : 100µW/VDELaser radiation from pick up unit is safety level, but be sure the followings: 1. Do not disassemble the optical pick up unit, since radiation from exposed laser diode is dangerous. 2. Do not adjust the variable resistor on the pick up unit. It was already adjusted. 3. Do not look at the focus lens using optical instruments. 4. Recommend not to look at pick up lens for a long time.

7 About Lead Free Solder (PbF)Distinction of PbF PCB: PCBs (manufactured) using lead free solder will have a Pbf stamp on the PCB.Caution:

· Pb free solder has a higher melting point than standard solder; Typically the melting point is 50 — 70°F (30 — 40°C) higher.Please use a high temperature soldering iron. In case of the soldering iron with temperature control,please set it to 700 ±20°F (370 ± 10°C).

· Pb free solder will tend to splash when heated too high (about 1100°F/ 600°C).

When soldering or unsoldering, please completely remove all of the solder on the pins or solder area, and be sure to heat thesoldering points with the Pb free solder until it melts enough.

16.2. Important points in adjustment16.2.1. Important points in optical adjustment · Before starting optical adjustment, be sure to take anti-static measures. · Optical pickup tilt adjustment is needed after replacement of the following components.

1. Optical pickup unit 2. Spindle motor unit 3. Optical pickup peripheral parts (such as rail)Notes

Adjustment is generally unnecessary after replacing other parts of the traverse unit. However, make adjustment if there is anoticeable degradation in picture quality. Optical adjustments cannot be made inside the optical pickup. Adjustment is generallyunnecessaryafter replacing the traverse unit.

16.2.2. Important points in electrical adjustment · Follow the adjustment procedures described in this Manual.

16.3. Storing and Handling Test Discs · Surface precision is vital for DVD test discs. Be sure to store and handle them carefully.

1. Do not place discs directly onto the workbench, etc., after use. 2. Handle discs carefully in order to maintain their flatness. Place them into their case after use and store them vertically. Store

discs in a cool place where they are not exposed to direct sunlight or air from air conditioners. 3. Accurate adjustment will not be possible if the disc is warped when placed on a surface made of glass, etc. If this happens, use

a new test disc to make optical adjustments. 4. If adjustment is done using a warped disc, the adjustment will be incorrect and some discs will not be playable.

the remote control unit. 2. Confirm that «J_xxx/yyy_zz» (display1/display2) is shown on

the front display.For your information:

«yyy» and «zz» shown to the right have nothing to do withthe jitter value. «yyy» is the error counter, while «zz» isthe focus drive value.

Note:Jitter value appears on the front display.

3. Play test disc T30 (center periphery). 4. Adjust tangential adjustment screw so that the jitter value is

minimized. 5. Play test disc T30 (center periphery). 6. Adjust tilt adjustment screw 1 so that the jitter value is

minimized. 7. Play test disc T30 (center periphery). 8. Adjust tilt adjustment screw 2 so that the jitter value is

minimized. 9. Repeat adjusting tilt adjustment screws 1 and 2 alternately

until the jitter value is minimized.

16.4.1.2. Important points 1. Make tangential adjustment first, and then make tilt

adjustment. 2. Repeat adjusting two or three times to find the optimum

point. 3. Finish the procedure with tilt adjustment.

Jitter value depends on the model: 1. If the jitter value changes like B, the optimum point is easy to

find.

2. If the jitter value changes like A, set the optimum point near themiddle.

16.4.1.3. Check after adjustmentPlay test disc or any other disc to make sure there is no picturedegradation in the inner, middle and outer peripheries, and noaudio skipping. After adjustment is finished, lock eachadjustment screw in position using screw lock.

16.4.1.4. Procedure for screw lock 1. After adjustment, remove top cover, tray, clamper base and

traverse unit in this sequence. 2. Lay the traverse unit upside down, and fix adjustment screw

· Indicated voltage values are the standard values for the unitmeasured by the DC electronic circuit tester (high-impedance) with the chassis taken as standard. Therefore,there may exist some errors in the voltage values,depending on theinternal impedance of the DC circuittester.

· Important safety notice:

Components identified by mark have specialcharacteristics important for safety.Furthermore, special parts which have purposes of fire-retardant (resistors), high-quality sound (capacitors), low-noise (resistors), etc. are used.When replacing any of components, be sure to use onlymanufacturer´s specified parts shown in the parts list.

· The supply part number is described alone in thereplacement parts list.

· Voltage and signal line

: +B Signal line: CD-DA signal line: Main signal line: DVD (Video) signal line: DVD (Audio) signal line: FM/AM signal line: -B Signal line

Caution!IC and LSI are sensitive to static electricity.Secondary trouble can be prevented by taking care duringrepair.Cover the parts boxes made of plastics with aluminum foil.Ground the soldering iron.Put a conductive mat on the work table.Do not touch the legs of IC or LSI with the fingers directly.
