Before returning an instrument to the customer, al- ways make a safety check of the entire instrument, in- cluding, but not limited to, the following items. a. Be sure that no built-in protective devices are d

23、efective and/or have been defeated during servicing. (1) Protective shields are provided on this chassis to protect both the technician and the customer. Correctly replace all missing pro- tective shields, including any removed for serv- icing convenience. (2) When reinstalling the chassis and/or ot

24、her assembly in the cabinet, be sure to put back in place all protective devices, including,but not limited to, nonmetallic control knobs,insulating fishpapers,adjustment and compartment covers/shields, and isolation re- sistor/capacitor networks. Do not operate this instrument or permit it to be op

25、erated with- out all protective devices correctly installed and functioning. b. Be sure that there are no cabinet openings through which an adult or child might be able to insert their fingers and contact a hazardous volt- age. Such opening include,but are not limited to, (1) spacing between the pic

26、ture tube and the cabinet mask, (2) excessively wide cabinet ven- tilation slots, and (3) an improperly fitted and/or incorrectly secured cabinet back cover. c. Leakage Current Hot Check With the instru- ment completely reassembled,plug the AC line cord directly into a 240V AC outlet. (Do not use an

27、 isolation transformer during this test.) Use a leakage current tester or a metering system that complies with American National Standards In- stitutes (ANSI) C101.1 Leakage Current for Ap- pliances and Underwriters Laboratories(UL) 1950. With the instrument AC switch first in the ON position and th

28、en in the OFF position, mea- sure from a known earth ground (metal waterpipe, conduit,etc.) to all exposed metal parts of the instrument(antennas, handle bracket, metal cabinet, screwheads, metallic overlays, control shafts,etc.), especially any ex- posed metal parts that offer an electrical return

29、path to the chassis. Any current measured must not exceed 3.5 milliamp. Reverse the instru- ment power cord plug in the outlet and repeat test.ANY MEASUREMENTS NOT WITHIN THE LIMITS SPECIFIED HEREIN INDICATE A POTENTIAL SHOCK HAZARD THAT MUST BE ELIMINATED BEFORE RETURNING THE INSTRUMENT TO THE CUST

30、OMER. AC Leakage Test 2. Read and comply with all caution and safety-related notes on or inside the Monitor cabinet, on the Pro- jection Monitor chassis, or on the picture tube. 3. Design Alteration Warning Do not alter or add to the mechanical or electrical design of this unit. Design alterations a

31、nd additions, including, but not limited to, circuit modifications and the addition of the items such as auxiliary audio and/or video out- put connections might alter the safety characteris- tics of this Monitor and create a hazard to the user. Any design alterations or additions will void the manuf

32、acturers warranty and will make you,the servicer,responsible for personal injury or property damage resulting therefrom. 4. Hot Chassis Warning a. Some MultiSync Monitor chassis are electrically connected directly to one conductor of the AC power cord and may be safely serviced without an isolation

33、transformer only if the AC power plug is inserted so that the chassis is connected to the ground side of the AC power source. To confirm that the AC power plug is in- serted correctly, with an AC voltmeter measure be- tween the chassis and a known earth ground. If a voltage reading in excess of 1.0V

34、 is obtained, re- move and reinsert the AC power plug in the oppo- site polarity and again measure the voltage poten- tial between the chassis and a known earth ground. b. Some Plasma chassis normally have 85V AC (RMS), between chassis and earth ground regard- less of the AC plug polarity. These cha

35、ssis can be safely serviced only with an isolation transformer inserted in the power line between the receiver and the AC power source, for both personnel and test equipment protection. c. Some Plasma chassis have a secondary ground systems in addition to the main chassis ground. This secondary grou

36、nd sys- tem is not isolated from the AC power line. The two ground system are electrically separated by insulat- ing material that must not be defeated or altered.

37、UG REVERSED (USING AC ADAPTER PLUG AS REQUIRED) DEVICE UNDER TEST 2-2 SAFETY PRECAUTIONS 5. Observe original lead dress. Take extra care to assure correct lead dress in the following areas: a. near sharp edges, b. near thermally hot parts be sure that leads and components do not touch thermally hot

38、parts, c. the AC supply, d. high volt- age, and e. antenna wiring. Always inspect in all areas for pinched, out-of-place, or frayed wiring. Do not change spacing between components, and be- tween components and the printed-circuit board. Check AC power cord for damage. 6. Components,parts, and/or wi

39、ring that appear to have overheated or are otherwise damaged should be replaced with components, parts, or wiring that meet original specifications. Additionally,determine the cause of overheating and/or damage and, if necessary, take corrective action to remove any potential safety hazard. 7. PRODU

40、CT SAFETY NOTICE Many MultiSync Monitor electrical and mechanical parts have spe- cial safety-related characteristics some of which are often not evident from visual inspection, nor can the protection they give necessarily be ob- tained by replacing them with components rated for higher voltage, wat

41、tage, etc. Parts that have special safety characteristics are identified in this service data by shading with a mark on schemat- ics and by shading or a mark in the parts list. Use of a substitute replacement part that does not have the same safety characteristics as the recom- mended replacement pa

42、rt in this service data parts list might create shock, fire, and/or other hazards. SAFETY PRECAUTIONS 2-3 1.
