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 "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 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 applying power to the 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 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 electrical 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 replacement
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 into which the device will be installed.
CAUTION :
8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together
or your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices.
Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
Each precaution in this manual should be followed during servicing.
Components identified with the IEC symbol in the parts list are special significance to safety. When replacing a component identified with
, use only the replacement parts designated, or parts with the same ratings or resistance, wattage, or voltage that are designated in the
parts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts are acceptably
insulated from the supply circuit before retuming the product to the customer.
SAFETY PRECAUTIONS
The following check should be performed 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, 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 AND MUST BE CORRECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER.

IMPORTANT NOTE: The AVR 330’s remote may be programmed to control up to eight devices, including the AVR 330. Before using the remote, it is important to remember to press the Input Selector Button e that corresponds to the unit you wish to operate. In addition, the AVR 330’s remote is shipped from the factory to operate the AVR 330 and most Harman Kardon CD or DVD players and cassette decks.The remote is also capable of operating a wide variety of other products using the control codes that are part of the remote. Before using the remote with other products, follow the instructions on pages 35–36 to program the proper codes for the products in your system.
It is also important to remember that many of the but­tons on the remote take on different functions, depend­ing on the product selected using the Device Control Selectors.The descriptions shown here primarily detail the functions of the remote when it is used to operate the AVR 330. (See page 36 for information about alternate functions for the remote’s buttons.)

Service bulletin # H/K2003-10 December 2003 To: All harman/kardon Service Centers Models: AVR130, AVR230, AVR330, HK3380, HK3480 Subject: Volume Level Changes On early versions of the AVR130,AVR230,AVR330,HK3380,HK3480, when the volume control is turned, the
volume level and display may be erratic, and not track accurately, or the level may progress in an unintended direction. This may happen on a random basis and depends on where the volume control knob is positioned after a volume adjustment. During a running production change, new volume encoders were installed.
In the event you receive an AVR model listed above with the complaint “The volume control on my receiver does not track accurately when turned”, perform the following procedure:
REPLACE VR74 (AVR130/230/330) or VR81 (HK3380/3480) VOLUME ENCODER
Note: It is important that t he various screws do not get mixed up and inserted in other locations upon reassembly. Mak e
note or label eac h r emoved screw set; keep them apar t from other screw sets.
1) Remove the top cover, (13) Phillips screws.
2) Remove the volume, bass, treble and balance knobs by 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 ass’y to the chassis: (6) at the bottom and (4) at the sides.
4) Cut all plastic cable ties that would prevent you detaching the front panel ass’y 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 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 ass’y. See below.
8) There should now be enough slack in the connecting cables to lift and detach the front panel ass’y from the chassis. Pull the front panel as far away as the remaining connecting wires will allow, enough to tilt and gain access to the rear of the Tone/Volume PCB. See illustrat ion 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) or CN83 (4 cond) if necessary.
11) Remove and replace VR74 or VR81 (5 soldered pads) with hk part# HSR2A029Z.
12) Reassemble in reverse order, taking care to replace all connectors, cable ties, and ground screw.
13) Power up receiver, and test volume control to assure setting no longer changes settings by itself, or when the volume knob is tapped.

Troubleshooting tips and solutions to common service problems

TIP# HKTT2004-03

Isolating audio problems in an AVR receiver
Using 6/8 Direct In
The following 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:
9 1 set of (RCA) Y adaptors. 9 Function/signal generator. 9 Oscilloscope.
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 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 jacks. 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 voltage at the line out jacks. ( -40 to -25db )

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 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 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 and confirmed that the problem is in the DSP section.
STOP! Go no further. At this point
