1 INTRODUCTION
This service manual contains technical which will alow service personnel's to understand and service this model. Please place orders using the parts list and not the drawing reference numbers. If the circuit is changed or modified, this information will be followed by supplement service manual to be filed with original service manual. 1. This service manual does not contain the following information, because of the impossibility of sevicing at component level. · Schematic Diagram, Block Diagram and P.C.B. layout of Digital P.C.B. and Back End P.C.B. · Parts List for individual parts of Digital P.C.B. and Back End P.C.B. · Exploded View and Parts List for individual parts of RAM drive. 2. The following category are recycle module part. Please send them to Central Repair Center. · Digital P.C.B. ES20DEB: RFKBES20DEB · RAM drive: VXY1867 · Back End P.C.B. : REPD0023A

2 SAFETY PRECAUTIONS
2.1. GENERAL GUIDELINES
1. Be careful during removing metal parts, sharp edges. 2. 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. 3. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed. 4. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.

2.1.2.

LEAKAGE CURRENT HOT CHECK

1. Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check. 2. Connect a 1.5k, 10 watts resistor, in parallel with a 0.15µF capacitors, 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 milliampere. In case a measurement is outside 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.

2.1.1.

LEAKAGE CURRENT COLD CHECK

1. Unplug the AC cord and connect a jumper between the two prongs on the plug. 2. Measure the resistance value, with an ohmmeter, between the jumpered AC plug and each exposed metallic cabinet part on the equipment such as screw heads, connectors, control shafts, etc. When the exposed metallic part has a return path to the chassis, the reading should be between 1M and 5.2M. When the exposed metal does not have a return path to the chassis, the reading must be infinity.

3 PREVENTION OF ELECTROSTATIC DISCHARGE (ESD) TO ELECTROSTATIC SENSITIVE (ES) DEVICES
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatic Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistor-sand semiconductor "chip" components. The following techniques should be used to help reduce the incidence of component damage caused by electrostatic 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 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 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 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 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 hamless 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).

4 PRECAUTION OF LASER DIODE
CAUTION: This product utilizes a laser diode with the unit turned "on", invisible laser radiation is emitted from the pickup lens. Wave length: 662 nm (DVDs)/795 nm (CDs) Maximum output radiation power from pickup: 100µ W/VDE. Laser radiation from the pickup lens is safety level, but be sure the followings: 1. Do not disassemble the optical pickup unit, since radiation from exposed laser diode is dangerous. 2. Do not adjust the variable resistor on the pickup unit. It was already adjusted. 3. Do not look at the focus lens using optical instruments. 4. Recommend not to look at pickup lens for a long time. ACHTUNG: Dieses Produkt enthält eine Laserdiode. Im eingeschalteten Zustand wird unsichtbare Laserstrahlung von der Lasereinheit ausgestrahlt. Wellenlänge: 662 nm(DVDs)/795 nm (CDs) Maximale Strahlungsleistung der Lasereinheit: 100µ W/VDE. Die Strahlung der eingeschalteten Lasereinheit ist ungefährlich, wenn folgende Punkte beachtet werden: 1. Die Lasereinheit nicht zerlegen, da die Strahlung an der freigelegten Laserdiode gefährlich ist. 2. Den werksseitig justierten Einstellregler der Lasereinheit nicht verstellen. 3. Nicht in die Fokussierlinse blicken. 4. Auch nicht mit optischen Instrumenten in die Fokussierlinse blicken.

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