AVR210 harman/kardon
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.

AVR210 harman/kardon
Before returning the unit to the user, perform the following safety checks :
1. Inspect all lead dress to make certain that
leads are not pinched or that hardware is not
lodged between the chassis and other metal
parts in the unit.
2. Be sure that any protective devices such as
nonmetallic control knobs, insulating fish-
papers, cabinet backs, adjustment and
compartment covers or shields, isolation
resistor-capacity networks, mechanical
insulators, etc. Which were removed for the
servicing are properly re-installed.
3. Be sure that no shock hazard exists ; check for leakage
current usingSimpson Model 229 Leakage Tester, standard
equipment item No. 21641, RCA Model WT540A or use
alternate method as follows : Plug the power cord directly
Into a 120 volt AC receptacle (do not use an Isolation
Transformer for this test). Using two clip leads, connect a
1500 ohms,10watt Resistor paralleledby a 0.15uFcapacitor,in series withall exposed metal cabinetparts and aknown earth ground,such
as a water pipe or conduit. Use a VTVM or VOM with 1000 ohms per volt, or higher sensitivity to measure the AC voltage drop across the
resistor. (See diagram) Move the resistor connection to each exposed metal part having a return path to the chassis (antenna, metal,
cabinet, screwheads, knobsand controlshafts, escutcheon, etc.) and measure the ACvoltage dropacross theresistor.(This test should be
performed withthe 0.35 volt RMS or more is excessive and indicates a potential shock hazardwhich must becorrected before returningthe
unit to the owner.

Letters flash in the channel indicator • Digital audio feed paused • Resume play for DVD
display and digital audio stops • Check that Digital Input is selected
Processor Reset
In the rare case where the unit’s operation or
the displays seem abnormal, the cause may
involve the erratic operation of the system’s
memory or microprocessor.
To correct this problem,first unplug the unit
from the AC wall outlet and wait at least three
minutes. After the pause, reconnect the AC
power cord and check the unit’s operation.If
the system still malfunctions,a system reset
may clear the problem.
To clear the AVR 210’s entire system memory
including tuner presets,output level settings,
delay times and speaker configuration data,
first put the unit in Standby by pressing the
System Power Control button 2. Next,
press and hold the Tone Mode 6 and the
FM Mode Selector @ buttons for three
seconds.
The unit will turn on automatically and display
the RESET message in the Main
Information Display X. Note that once you
have cleared the memory in this manner, it is
necessary to reestablish all system configuration
settings and tuner presets.
NOTE:Resetting the processor will erase any
configuration settings you have made for
speakers,output levels, surround modes,digital
input assignments as well as the tuner presets.
After a reset the unit will be returned to the
factory presets,and all settings for these items
must be reentered.
If the system is still operating incorrectly,there
may have been an electronic discharge or
severe AC line interference that has corrupted
the memory or microprocessor.
If these steps do not solve the problem, consult
an authorized Harman Kardon service depot.

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 )

Isolating audio problems in an AVR receiver
Using 6/8 Direct 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
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
