Leakage-current or resistance measurements must be made to determine that exposed parts are acceptably insulated from the supply circuit before retuming th

5、e product to the customer. 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 ch

6、ip 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 component or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touching a known ear

7、th ground. Alternatively, obtain and wear a commercially 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 conductive

8、 surface such as aluminum 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 removal device. Some solder removal devices not classified as anti-static can generate e

9、lectrical charges sufficient to damage ES devices. 5. Do not use freon-propelled chemicals. These can generate electrical change 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 replaceme

10、nt 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

11、 into which the device will be installed. 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 or your clothes fabric or th

12、e lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices.

13、for the continued protection of the customer and service technician. LEAKAGE CURRENT CHECK Measure leakage current to a known earth ground (water pipe, conduit, etc.) by connecting a leakage current tester between the earth ground and all exposed metal parts of the appliance (input/output terminals,

14、 screwheads, metal overlays, control shaft, etc.). Plug the AC line cord of the appliance directly into a 120V AC 60Hz outlet and turn the AC power switch on. Any current measured must not exceed o.5mA. ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD

15、AND MUST BE CORRECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER. Device under test Test all exposed metal surfaces Also test with plug reversed (Using AC adapter plug as required) AC Leakage Test Leakage current tester Reading should not be above 0.5mA Earth ground AVR130 AVR130 harman/kardon w

20、n your listening room. (See pages 1619 for more information on speaker setup and configuration.) 7 Surround Mode Group Selector: Press this button to select the top-level group of surround modes. Each press of the button will select the current mode in each of the major groupings (e.g., Dolby, DTS,

21、Logic 7, DSP, Stereo). When the button is pressed so that the name of a mode in the desired surround-mode group appears in the on- screen display and in the Lower Display Line , press the Surround Mode Selector 8 to cycle through the individual modes available. For example, press this button to sele

24、 pulling them straight out and off. If a tool is necessary for removal of the smaller knobs, make sure the jaws are insulated to avoid knob damage. 3) Remove the (10) Phillips screws holding the front panel assy to the chassis: (6) at the bottom and (4) at the sides. 4) Cut all plastic cable ties th

25、at would prevent you detaching the front panel assy from the chassis. Draw a diagram if necessary, for a location reminder, to aid reassembly. 5) Unplug connector CN15 (6 cond) or CN89 (7 cond) at the left side of the unit. See below. 6) Remove single ground screw at the left side of the unit, near

26、CN15 or CN89. (Black wire) 7) Unplug connector CN72 (32 cond) or CN81 (20 cond) on the DSP PCB, coming from the top of the front panel assy. See below. 8) There should now be enough slack in the connecting cables to lift and detach the front panel assy from the chassis. Pull the front panel as far a

27、way as the remaining connecting wires will allow, enough to tilt and gain access to the rear of the Tone/Volume PCB. See illustration Page 2. 9) Remove the (10) screws or (9) screws holding the Tone/Volume PCB to the front panel. 10) Detach and pull back the PCB; unplug top connector CN84 (7 cond) o

34、charts are used to help the tech quickly isolate audio problems in an AVR receiver. Use the following procedures to help find what is working, then to quickly locate the problem area. Equipment needed: ? 1 set of (RCA) Y adaptors. ? Function/signal generator. ? Oscilloscope. Models covered: AVR210 A

35、VR310 AVR220 AVR320 AVR520 AVR225 AVR125 AVR525 AVR130 AVR230 AVR330 AVR430 AVR630 Procedure: 1) Do a factory reset of the receiver. (This will eliminate any common micro processor problems.) Reset List can be found in this service manual. 2) Print the block diagram from the service manual. 3) With

36、no inputs or speakers attached to the AVR turn on the receiver and turn the volume all the way down. 4) Turn unit off. 5) Hook up an oscillator to the 6/8 Direct in jacks using the Y adaptors. Adjust the oscillator to about 0db (.775Volts RMS). 6) Hook up an oscilloscope to monitor the line out jack

37、s. Or, if there are no line out (preamp out) jacks monitor the input to the power amps or the speaker outs. (AVR125, 225, 130 do not have preamp out jacks) 7) Turn the AVR on. Select 6 or 8 direct in, depending on the receiver. 8) Slowly turn the volume control up until you can easily measure the vo

38、ltage at the line out jacks.

39、 In 9) At this point you will be able to check and assure all output levels are the same. 10) IF THE OUTPUT LEVELS ARE NOT THE SAME STOP! Go no further. At this point you will need to use the charts to see where you are losing your signal. The chart shows the analog signal flow from the input jacks

40、to the output jacks. 11) If the output levels are the same check the power out stage at the speaker out jacks. 12) If you find the levels at the speaker out jacks are OK, your problem will be in the DSP part of the receiver. Congratulations! You have now eliminated 90% of the electronics in the AVR

41、and confirmed that the problem is in the DSP section.
