AVR110 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.

AVR110 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.

• Stereo or Mono program material • The surround decoder may not create center- or rear-channel

information from nonencoded programs

Unit does not respond to • Weak batteries in remote • Change remote batteries remote commands • Wrong device selected • Press the AVR selector

• Remote sensor is obscured • Make certain front panel sensor is visible to remote

or connect remote sensor

Intermittent buzzing in tuner • Local interference • Move unit or antenna away from computers,fluorescent

lights,motors or other electrical appliances

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 110’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 W. 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.

Service bulletin # H/K2001-03 Rev1 January 2003

To: All harman/kardon Service Centers

Models: AVR110/210/310/510

Subject: No Output In Surround Mode

In the event you receive an AVR110,210,310, or 510 A/V receiver with the complaint: “The receiver has no output when any surround mode is chosen, when using any input, digital or analog.”, check the item below for a possible solution:

Probable Cause: Defective IC4 EEPROM AT27LV020 on the DSP board.

Solution: Replace IC4 (called IC04 in the parts list) following these instructions:

1) Remove the top cover, (14) Black Phillips screws at the sides and rear of the unit.

2) Locate the DSP PC Board; Figure 1. Remove the metal brace at the top of the unit.

3) Pull the white 21 conductor ribbon cable at the rear of the DSP PC Board straight out of its receptacle.

4) Unplug the multicolor 5 conductor molex cable at the top of the DSP PC Board.

5) Remove the (33) black Phillips screws on the left side of the rear backplate; see Figure 2. Do not remove any additional screws on the right side. Remove all three black plastic plugs that cover the optical inputs at the rear of the DSP PC Board.

6) Pull on the left side of the rear backplate, away from the receiver chassis; you should be able to pull it away enough to allow the DSP PC Board to be pulled straight up and out of the receiver. If necessary, cut any additional cable ties that would prevent removal of the DSP board.

7) Replace IC4 (called IC04 in the parts list); obtain part number from chart below. Caution: IC4 is an electrostatically sensitive device and can be damaged by careless handling; you must follow proper static control procedures to prevent damage to the IC.

8) Replace DSP PC Board and follow the above procedures in reverse order. Screws: If using a power tool, use care and minimum effort to avoid damaging the various plastic receptacles.

9) Test unit to assure original problem has been corrected.
