7、HANDLING OF THE PICK-UP 1. Notes for transport and storage 1) The pick-up should always be left in its conductive bag until immediately prior to use. 2) The pick-up should never be subjected to external pressure or impact. 2. Repair notes 1) The pick-up incorporates a strong magnet, and so should ne

8、ver be brought close to magnetic materials. 2) The pick-up should always be handled correctly and carefully, taking care to avoid external pressure and impact. If it is subjected to strong pressure or impact, the result may be an operational malfunction and/or damage to the printed-circuit board. 3)

9、 Each and every pick-up is already individually adjusted to a high degree of precision, and for that reason the adjustment point and installation screws should absolutely never be touched. 4) Laser beams may damage the eyes! Absolutely never permit laser beams to enter the eyes! Also NEVER switch ON

10、 the power to the laser output part (lens, etc.) of the pick-up if it is damaged. 5) Cleaning the lens surface If there is dust on the lens surface, the dust should be cleaned away by using an air bush (such as used for camera lens). The lens is held by a delicate spring. When cleaning the lens surf

11、ace, therefore, a cot- ton swab should be used, taking care not to distort this. 6) Never attempt to disassemble the pick-up. Spring by excess pressure. If the lens is extremely dirty, apply isopropyl alcohol to the cotton swab. (Do not use any other liquid cleaners, because they will damage the len

12、s.) Take care not to use too much of this alcohol on the swab, and do not allow the alcohol to get inside the pick-up. Storage in conductive bag NEVER look directly at the laser beam, and dont let contact fingers or other exposed skin. Magnet How to hold the pick-up Conductive Sheet Cotton swab Pres

13、sure Pressure Drop impact RadioFans.CN 2 NOTES REGARDING COMPACT DISC PLAYER REPAIRS 1. Preparations 1) Compact disc players incorporate a great many ICs as well as the pick-up (laser diode). These compo- nents are sensitive to, and easily affected by, static electricity. If such static electricity

14、is high voltage, components can be damaged, and for that reason components should be handled with care. 2) The pick-up is composed of many optical components and other high-precision components. Care must be taken, therefore, to avoid repair or storage where the temperature of humidity is high, wher

15、e strong magnetism is present, or where there is excessive dust. 2. Notes for repair 1) Before replacing a component part, first disconnect the power supply lead wire from the unit 2) All equipment, measuring instruments and tools must be grounded. 3) The workbench should be covered with a conductiv

16、e sheet and grounded. When removing the laser pick-up from its conductive bag, do not place the pick-up on the bag. (This is because there is the possibility of damage by static electricity.) 4) To prevent AC leakage, the metal part of the soldering iron should be grounded. 5) Workers should be grou

17、nded by an armband (1M) 6) Care should be taken not to permit the laser pick-up to come in contact with clothing, in order to prevent static electricity changes in the clothing to escape from the armband. 7) The laser beam from the pick-up should NEVER be directly facing the eyes or bare skin.

Such components com- monly are called Electrostatically

19、 Sensitive Devices (ESD). Examples of typical ESD devices are integrated cir- cuits 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 handli

20、ng any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device, which should be removed for potential shock reasons prior to ap

21、plying power to the unit under test. 2. After removing an electrical assembly equipped with ESD devices, place the assembly on a conductive sur- face 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 uns

22、older ESD devices. 4. Use only an anti-static solder removal device. Some solder removal devices not classified as anti-static can generate electrical charges sufficient to damage ESD devices. 5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ESD dev

23、ices. 6. Do not remove a replacement ESD device from its protective package until immediately before you are ready to install it. (Most replacement ESD devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive materials). 7. Immediately

24、before removing the protective material from the leads of a replacement ESD device, touch the protective material to the chassis or circuit assembly into which the device will by installed. CAUTION : BE SURE NO POWER IS APPLIED TO THE CHASSIS OR CIRCUIT, AND OBSERVE ALL OTHER SAFETY PRECAUTIONS. 8.

25、Minimize bodily motions when handing unpackaged replacement ESD devices. (Otherwise harmless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can gen- erate static electricity sufficient to damage an ESD device). harman/kardon service manu

40、ng guide to help you remedy the problem. Should any problem persist, consult your authorized Harman Kardon dealer. No power. Is the power cord firmly plugged into the power outlet? One of the safety mechanisms may be operat- ing. In this event, unplug the player from the power outlet briefly and the

41、n plug it in again. No picture. Check that the system is connected correctly and securely. The video cable may be damaged. Replace it with a new one. Make sure the system is connected to a video input on the TV (see page 14). Make sure the TV is turned on. Make sure the correct video input on the TV

42、 is selected for viewing with this system. Noise (interference) appears in the picture. Clean the disc. If video from this system has to go through your VCR to get to your TV, the copy-protection applied to some DVD programs could affect picture quality. If you still experience problems after checki

43、ng your connections, please try con- necting your DVD system directly to your TVs S-Video input, if your TV is equipped with this input (see page 14). The aspect ratio of the screen is wrong (picture vertically expanded) when you play a wide picture even though you set “TV DISPLAY” in the SETUP menu

44、 to 16:9. If you connect the system with the SCART cable, connect directly to the TV. Otherwise the autoswitch function of the aspect ratio for the TV may not work. If the TV is not connected with a SCART cable to the HS, or if the autoswitch function does not work you should turn the TV to 16:9 (if

45、 possible with your TV). Depending on the TV, you may not be able to change the aspect ratio. In that case (TV not adjustable to 16:9) do not select 16:9 in the TV Display.Then, no change of the aspect ratio is needed. There is no sound or volume is very low. Check that the speakers and components a

46、re connected correctly and securely. Make sure that you have selected the correct source on the system. Press MUTE on the remote control, if the words MUTE ON are blinking on the front panel display. The protective circuitry has been activated because of a short circuit.Turn off the system, eliminat

47、e the short circuit problem and turn on the power again. The audio interconnect is damaged. Replace it with a new one. The system is in pause mode or in slow-motion play mode, or fast forward or fast reverse. Press Nto return to normal play mode. Check the speaker settings (see page 19). The left an

48、d right channels are unbalanced or reversed. Check that the speakers and components are connected correctly and securely. Severe hum or noise is heard. Check that the speakers and components are connected securely. Check that the connecting cords are away from a transformer or motor and at least 3 m

49、eters away from fluorescent light. Move your TV away from the audio compo- nents. The plugs and jacks are dirty.Wipe them with a cloth slightly moistened with alcohol. Clean the disc. The surround effect is difficult to hear when you are playing a Dolby Digital sound track. Check to see if the Dolby Digital mode is turned on properly, otherwise unload and load the disc again. Check the speaker connections. Dependin
