2 Before Repair and Adjustment

Disconnect AC power, discharge Power Supply Capacitors C1140 , C1250, C1280, C1128, C1121 , C1125 & C1126 through a 10

, 1W resistor to ground.

Ω

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 consum ption at AC 120V, 60Hz in NO SIGNAL mode should be ~318 mA.

3 Protection Circuitry

The protection circuitry may have operated if either of the following conditions is noticed:

No sound is heard when the power is switched ON.

Sound stops during a performance.

The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative speake r connection wires are

shorted, or if speaker systems with an impedance less than the indicated rated impedance of this unit are used.

If this occurs, follow the procedure outlines below:

1. Switch OFF the power.

2. Determine the cause of the problem and correct it.

3. Switch ON the power once again.

Note :

When the protection circuitry functions, the unit will not operate unless the power is first switched OFF and then ON again.

4 Safety Precautions

4.1. 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, ensure that all the protective devices such as insulation barriers, insulation papers shields are properly installed.

3. After servicing, check for leakage current checks to prevent from being exposed to shock hazards.

(This

“Safety Precaution” is applied only in U.S.A.)

1. Before servicing, unplug the power cord to prevent an electric shock.

2. When replacing parts, use only manufacturer’s recommended components for safety.

3. Check the condition of the power cord. Replace if wear or damage is evident.

4. After servicing, be sure to restore the lead dress, insulation barriers, insulation papers, shields, etc.

5. Before returning the serviced equipment to the customer, be sure to make the following insulation resistance test to prevent the customer from being exposed to a shock hazard.

4.1.1. Leakage Current Cold Check

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

2. Using an ohmmeter measure the resistance value, between the jumpered AC plug and each exposed metallic cabinet part on the equipment such as screwheads, connectors, control shafts, etc. When the exposed metallic part has a return path to the chassis, the reading should be between 1MΩ and 5.2MΩ . When the exposed metal does not have a return path to the chassis, the reading must be

Fig. 1

4.1.2. Leakage Current Hot Check (See Figure 1)

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

2. Connect a 1.5kΩ, 10 watts resistor, in parallel with a 0.15µF capacitor, between each exposed metallic part on the set and a good earth ground such as a water pipe, as shown in Figure 1.

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

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

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

6. The potential at any point should not exceed 0.75 volts RMS. A leakage current tester (Simpson Model 229 or equivalent) may be used to make the hot checks, leakage current must not exceed 1/2 milliamp. Should the measurement is out of the limits specified, there is a possibility of a shock hazard, and the equipment should be repaired and rechecked before it is returned to the customer.

4.1.3. Caution for fuse replacement

5 Handling the Lead-free Solder

5.1. About lead free solder (PbF)

Distinction of PbF P.C.B.:

P.C.B.s (manufactured) using lead free solder will have a PbF stamp on the P.C.B.

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 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).

· W hen soldering or unsoldering, please completely remove all of the solder on the pins or solder area, and be sure to heat the

soldering points with the Pb free solder until it melts enough.

6 Prevention of Electro Static Discharge (ESD) to

Electrostatically Sensitive (ES) Devices

Some semiconductor (solid state) devices can be damaged easily by 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 electro static discharge (ESD).

1. Immediately before handling any semiconductor component or semiconductor-equiped assembly, drain off any ESD on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD 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 equiped with ES devices, place the assembly on a conductive surface such as aluminium foil, to prevent electrostatic charge build up 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 remover device. Some solder removal devices not classified as “anti-static (ESD protected)” can generate electrical charge 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, aluminium 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 body 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 (ESD) sufficient to damage an ES device).

n Use of Caution Labels

8.1. Cautions to be taken during replacement of optical pickup

Optical pickup could be damaged due to the static electricity discharged from human body. Wear proper protection gear against static electricity during optical pickup and its peripheral repair. (Refer to the section regarding protection against static electricity.)

1. Do not touch laser diode, actuator and their peripherals.

2. Do not check laser diode with a tester and such. (The tester will be destroyed.)

3. For short-circuiting or removing laser diode, the use of an anti-static soldering iron is recommended. (Recommended model: HAKKO ESD product)

4. Solder the land of the flexible cable in the optical pickup.

Note:

· If an anti-static soldering iron is not available, short-circuit the terminal surface of the flexible cable and then the land using

a clip or equivalent device.

· For short-circuit of the above laser diode, remove soldering as instructed in this manual after completing repair.

11 CHECKING POINTS FOR SYS COM TIMER MY-COM

(IC6001) (VIDEO)

11.1. Points to check when replacing

When the replacing the Sys Com Timer My-Com (IC6001), surely check the contents of data of a microcomputer before replacing. When the Program Navi is "ON", take backup before replacing and set the initial value. *It also carries out at the time of replacing the P.C.B

(The procedure)

1. Before replacing IC6001, please record and keep the channel of already set-up TV broadcast. The backup of the program navi is also required since IC6001 already stores the program navi data. Please surely take the backup when the navi data is "ON".

*The procedure of checking the program navi data without a cassette.

a. Press both "EJECT" and "FF" buttons in the same time for 3 seconds and start the Service Mode.

b. Push the button of program navi on the remote controller for 5 seconds.

c. The program navi data is shown on the monitor.

2. After replacing IC6001, switch on the power supply of the VIDEO.

3. Short out TL6002 and TL6004 on the Main P.C.B by short jumper.

4. Initialise the Sys Com Timer My-Com as below.

5. After that, short out the TL7501 and TL7502 on the Main P.C.B. by short jumper twice to make the factory setting. (Unless carrying out the Factory Setting, the indication of the line-in doesn´t appear on the FIP panel).

6. After carrying out the procedure 1. to 5. as above please adjust the PG shifter.

11.2. Initial setting when replacing My-com.

1. Initial setting is an important function in order to guarantee as a product correctly. Unless it inputs the number according to the model, it cannot operate correctly.

2. Once the initial-setting value set up, even if a microcomputer (IC6001) is reset, it has memorized.

3. Be sure to set the initial-setting value when replacing the Main P.C.B. with a microcomputer (IC6001).

4. The RAM inside of the microcomputer (IC6001) stores the PG self-adjustment. Be sure to do the PG self-adjustment when the Sys Com Timer My-Com, the P.C.B. with microcomputer, and cylinde r unit are replaced.

11.3. Initial figure (#) setting procedure

12.2. Necessity of Adjustment

12.2.1. Necessity of Optical Adjustment

· Before starting optical system adjustment, be sure to wear proper protection gear against static electricity.

· Optical adjustment (optical pickup tilt adjustment) is required after following parts are replaced:

1. Optical pickup

2. Spindle motor assembly

3. Optical pickup peripherals such as a rail, etc.

Note:

Optical adjustment is not necessary after replacement of other parts inside traverse, however, may require when picture deterioration is detected. Optical adjustment cannot be applied to the inside of optical pickup. When a traverse unit is replaced, the adjustment is not necessary.

12.2.2. Necessity of Electrical Adjustment

· Follow the procedure for adjustment.

12.3. Storing and Handling Test Discs

· Surface precision is vital for DVD test discs. Be sure to store and handle them carefully.

1. Do not leave the discs uncovered on the work desk or other places after use.

2. Handle the discs carefully to prevent scratches. Put each disc in its case and place it in the standing position. Store the discs

in a cool place and avoid direct sunlight or air conditioner.

3. Accurate adjustment cannot be expected with a disc warped against a flat surface. Obtain a new test disc for optical adjustment.

4. If a warped disc is used, adjustment would result incorrectly, and other discs could not be used.
