SERVICE INFORMATION While servicing, use

11、an isolation transformer for protection from AC line shock. After the original service problem has been corrected, make a check of the following: FIRE AND SHOCK HAZARD 1. Be sure that all components are positioned to avoid a possibility of adjacent com- ponent shorts. This is especially important on

12、 items trans-ported to and from the repair shop. 2. Verify that all protective devices such as insulators, barriers, covers, shields, strain reliefs, power supply cords, and other hardware have been reinstalled per the original design. Be sure that the safety purpose of the polarized line plug has n

13、ot been defeated. 3. Soldering must be inspected to discover possible cold solder joints, solder splashes, or sharp solder points. Be certain to remove all loose foreign particles. 4. Check for physical evidence of damage or deterioration to parts and components, for frayed leads or damaged insulati

14、on (including the AC cord), and replace if necessary. 5. No lead or component should touch a high current device or a resistor rated at 1 watt or more. Lead tension around protruding metal surfaces must be avoided. 6. After reassembly of the set, always perform an AC leakage test on all exposed meta

15、llic parts of the cabinet (the channel selector knobs, antenna terminals, handle and screws) to be sure that set is safe to operate without danger of electri- cal shock. DO NOT USE A LINE ISOLATION TRANSFORMER DURING THIS TEST. Use an AC voltmeter having 5000 ohms per volt or more sensitivity in the

16、 following manner: Connect a 1500 ohm, 10 watt resistor, paralleled by a .15 mfd 150V AC type capacitor between a known good earth ground water pipe, con- duit, etc.) and the exposed metallic parts, one at a time. Measure the AC voltage across the combination of 1500 ohm resistor and .15 mfd capacit

17、or. Reverse the AC plug by using a non-polarized adaptor and repeat AC voltage measurements for each exposed metallic part. Voltage measured must not exceed 0.75 volts RMS. This corresponds to 0.5 milliamp AC. Any value exceeding this limit consti- tutes a potential shock hazard and must be correcte

18、d immediately. TIPS ON PROPER INSTALLATION 1. Never install any receiver in a closed-in recess, cubbyhole, or closely fitting shelf space over, or close to, a heat duct, or in the path of heated air flow. 2. Avoid conditions of high humidity such as: outdoor patio installations where dew is a factor

19、, near steam radiators where steam leakage is a factor, etc. 3. Avoid placement where draperies may obstruct venting. The customer should also avoid the use of decorative scarves or other coverings that might obstruct ventilation. 4. Wall- and shelf-mounted installations using a commercial mounting

20、kit must follow the factory-approved mounting instructions. A product mounted to a shelf or plat- form must retain its original feet (or the equivalent thickness in spacers) to provide adequate air flow across the bottom. Bolts or screws used for fasteners must not touch any parts or wiring. Perform

21、 leakage tests on customized installations. 5. Caution customers against mounting a product on a sloping shelf or in a tilted position, unless the receiver is properly secured. 6. A product on a roll-about cart should be stable in its mounting to the cart. Caution the customer on the hazards of tryi

22、ng to roll a cart with small casters across thresholds or deep pile carpets. 7. Caution customers against using extension cords. Explain that a forest of exten- sions, sprouting from a single outlet, can lead to disastrous consequences to home and family. 1-4 SERVICING PRECAUTIONS CAUTION: Before se

23、rvicing the 3D NETWORK BLU-RAY / DISC PLAYER covered by this service data and its supplements and addends, read and follow the SAFETY PRECAUTIONS. NOTE: if unforeseen circumstances create conflict between the following servicing precautions and any of the safety precautions in this publication, alwa

24、ys follow the safety pre- cautions. Remember Safety First : General Servicing Precautions 1. Always unplug the 3D NETWORK BLU-RAY / DISC PLAYER AC power cord from the AC power source before: (1) Removing or reinstalling any component, circuit board, module, or any other assembly. (2) Disconnecting o

25、r reconnecting any internal electrical plug or other electrical connection. (3) Connecting a test substitute in parallel with an electro- lytic capacitor. Caution: A wrong part substitution or incorrect polarity installation of electrolytic capacitors may result in an explosion hazard. 2. Do not spr

26、ay chemicals on or near this 3D NETWORK BLU-RAY / DISC PLAYER or any of its assemblies. 3. Unless specified otherwise in this service data, clean elec- trical contacts by applying an appropriate contact cleaning solution to the contacts with a pipe cleaner, cotton-tipped swab, or comparable soft app

27、licator. Unless specified otherwise in this service data, lubrication of contacts is not required. 4. Do not defeat any plug/socket B+ voltage interlocks with which instruments covered by this service manual might be equipped. 5. Do not apply AC power to this 3D NETWORK BLU-RAY / DISC PLAYER and / o

28、r any of its electrical assemblies unless all solid state device heat sinks are correctly installed. 6. Always connect the test instrument ground lead to an appropriate ground before connecting the test instrument positive lead. Always remove the test instrument ground lead last. Insulation Checking

29、 Procedure Disconnect the attachment plug from the AC outlet and turn the power on. Connect an insulation resistance meter (500V) to the blades of the attachment plug. The insulation resis- tance between each blade of the attachment plug and acces- sible conductive parts (Note 1) should be more than

30、 1Mohm. Note 1: Accessible Conductive Parts include Metal panels, Input terminals, Earphone jacks,etc. Electrostatically Sensitive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) D

31、evices. 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 static electricity. 1. Immediately before handling any semiconductor

32、compo- nent or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a commer- cially available discharging wrist strap device, which should be removed for potential shock reasons prior to applying power to t

33、he 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.

34、 Use only an anti-static solder removal device. Some solder removal devices not classified as “anti-static” can generate electrical charges sufficient to damage ES devices. 5. Do not use freon-propelled chemicals. These can generate an electrical charge sufficient to damage ES devices. 6. Do not rem

35、ove 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 p

36、rotective 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 cir- cuit, and observe all other safety precautions. 8. Minimize bodily motio

37、ns when handling unpackaged replacement ES devices. (Normally harmless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static elec- tricity sufficient to damage an ES device.) 1-5 SOFTWARE UPGRADE 1-6 SPECIFICATIONS GENERAL P
