1. SAFETY PRECAUTIONS
1.1. 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
5 2005-05-13
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. (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.
1.1.1. 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 screwheads, connectors, control shafts, etc. When the exposed metallic part has a return path to the chassis,the reading should be between 1M and 5.2 . When the exposed metal does not have a return path to the chassis, the reading must be .

2005-05-13
1.1.2. 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 1.5k , 10 watts resistor, in parallel with a 0.15 F 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 milliamp. In case a measurement is outsideof 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. Handling the Lead Solder
2.1. 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 that 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 temperaturecontrol, 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.
3. Before Repair and Adjustment
7 2005-05-13
Disconnect AC power, discharge Power Supply Capacitors C527, C528, C529, C530, C561 through a 10 , 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 120V, 60Hz in NO SIGNAL mode should be 850 mA .
4. Protection Circuitry
The 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.

8. About HighMAT
8.1. What is HighMAT?
This word combines the abbreviations of Matsushita Electric Industrial Co., Ltd. and High Performance Media Access Technology, and is a trademark of Microsoft Corporation. The products with the HighMAT logo shown below are made according to theHighMAT standard.
10
2005-05-13
HighMat is a format that allows users to save digital contents such as photographs, audio and images on a CD. This gives consistency in the way of reading data when general consumer products (such as DVD players) and PCs are used, and thus, it iseasy to operate for the user.
8.2. Why use HighMAT?
Up to now, there was no harmonized standard from playing digital content stored in CD-ROM formats (including CD-R) on consumer products like DVD players. Therefore, we used to have problems such as follow:
- There was no common play list or attached information on contents, which is
called metadata.
- The data compression method differed according to the equipment. - As the number of CD-ROMs recorded increased retrieved the contents became
more difficult.
- Because display and operation methods were different depending on the
equipment, the play order of the content on the same disc could change.
8.3. The advantages of using HighMAT
Applying the HighMAT standard will solve the following problems and will improve usability.
- It will create a common user interface for both PC and consumer products.
11
2005-05-13
- Regardless of the types of consumer products, such as DVD players, portable
CD players, car stereos and minicomputers, a consistent way to play for digital content will be created, and it will make it easier to retrieve data.
12
2005-05-13
- You can also play digital content on the disc, which was created in accordance
with the HighMAT format with a conventional CD-ROM player.
8.4. Outline of the HighMAT standard

9. 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 transistorsand 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 semiconductorequiped 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, whichshould 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 orcomparable 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 (ESD)sufficient to damage an ES device).

11. Handling Precaution for Traverse Deck (Optical Pickup)
The laser diode in the traverse unit (optical pickup) may break down due to static electricity of clothes or human body. Use due caution to electrostatic breakdown when servicing and handling the laser diode.
11.1. Grounding for electrostatic breakdown prevention
Some devices such as the DVD player use the optical pickup (laser diode) and the optical pickup will be damaged by static electricity in the working environment. Proceed servicing works under the working environment where grounding works is completed.
11.1.1. Workable grounding
1. Put a conductive materials (sheet) or iron sheet on the area where the optical pickup is placed, and ground the sheet.
11.1.2. Human body grounding
1. Use the anti-static wrist strap to discharge the static electricity from your body.
17
2005-05-13
11.1.3. Handling of optical pickup
1. To keep the good quality of the optical pickup maintenance parts during transportation and before installation,. the both ends of the laser diode are short -circuited. After replacing the parts with new ones, remove the short circuit accordingto the correct procedure. (See this Technical Guide.) 2. Do not use a tester to check the laser diode for the optical pickup. Failure to do so will damage the laser diode due to the power supply in the tester.
11.2. Handling Precautions for Traverse Unit (Optical Pickup)
1. Do not give a considerable shock to the traverse unit (optical pickup) as it has an extremely high-precise structure. 2. When replacing the optical pickup, install the flexible cable and cut its short land with a nipper. See the optical pickup replacement procedure in this Technical Guide. Before replacing the traverse unit, remove the short pin for preventingstaticelectricity and install a new unit. Connect the connector as short times as possible. 3. The flexible cable may be cut off if an excessive force is applied to it. Use caution when handling the cable. 4. The half-fixed resistor for laser power adjustment cannot be adjusted. Do not turn the resistor.
