THE ONLY POTEN- TIAL SOURCE OF X-RAYS IN CURRENT T.V. RECEIVERS IS THE PIC- TURE TUBE. HOWEVER, THIS TUBE

6、 DOES NOT EMIT X-RAYS WHEN THE HIGH VOLTAGE IS AT THE FACTORY SPECIFIED LEVEL. THE PROPER VALUE IS GIVEN IN THE APPLICABLE SCHEMATIC. OPERA- TION AT HIGHER VOLTAGES MAY CAUSE A FAILURE OF THE PIC- TURE TUBE OR HIGH VOLTAGE SUPPLY AND, UNDER CERTAIN CIR- CUMSTANCES, MAY PRODUCE RADIATION IN EXCESS OF

NOTE : if unforeseen circum- stances create conflict between the following servicing pre- cautions and any of the safety precautions in this publica- tions, always follow the safety pre

20、cautions. Remembers Safety First: General Servicing Precautions 1. Always unplug the DVD AC power cord from the AC power source before: (1)Removing or reinstalling any component, circuit board, module, or any other assembly. (2)Disconnection or reconnecting any internal electrical plug or other elec

21、trical connection. (3)Connecting a test substitute in parallel with an elec- trolytic capacitor. Caution : A wrong part substitution or incorrect polarity installation of electrolytic capacitors may result in an explosion hazard. 2. Do not spray chemicals on or near this DVD or any of its assemblies

22、. 3. Unless specified otherwise in this service data, clean electrical contacts by applying an appropriate contact cleaning solution to the contacts with a pipe cleaner, cotton-tipped swab, or comparable soft applicator. Unless specified otherwise in this service data, lubrication of contacts is not

23、 required. 4. Do not defeat any plug/socket B+ voltage interlocks with whitch instruments covered by this service manual might be equipped. 5. Do not apply AC power to this DVD and/or any of its electrical assemblies unless all solid-state device heat sinks are cerrectly installed. 6. Always connect

24、 test instrument ground lead to the appropriate ground before connection the test instrument positive lead. Always remove the test instrument ground lead last. Insulation Checking Procedure Disconnect the attachment plug from the AC outlet and turn the power on. Connect an insulation resistance mete

25、r(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 1M- ohm. Note 1 : Accessible Conductive Parts including Metal pan- els, Input terminals, Earphone jacks, etc. Electrostat

26、ically Sensitive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static 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

27、 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 compo- nent or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touching a know

28、n 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 the unit under test. 2. After removing an electrical assembly equipped with ES devices, place the assembly on a con

29、ductive surface such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly. 3. Use only a grouned-tip soldering iron to solder or unsolder ES devices. 4. Use only an anti-static solder removal device. Some solder removal devices not classified a “anti-static” can gene

30、rate electrical charges sufficient to damage ES devices. 5. Do not use freon-propelled chemicals. These can generate electrical charge sufficient to damage ES devices. 6. Do not remove a replacement ES device from its protec tive package until immediately before you are ready to install it. (Most re

31、placement 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

32、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. (Normally harmless motion such as the brushing together of your clo

33、thes fabric or the lifting of your foot from a carpeted floor can generate static elec- tricity sufficient to damage an ES device.) 1-5 SPECIFICATIONS GENERAL Power requirements:AC 100-240 V , 50/60 Hz Power consumption: 45W Dimensions (Approx.):435 x 80 x 286 mm (W x H x D) without foot Weight (App
