AVR8000 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.

AVR8000

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

harman/kardon

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 metalcabinet parts anda known earthground, 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 theAC voltagedrop across the resistor. (This test shouldbe

performed withthe 0.35 volt RMS or more is excessiveand indicates apotential shock hazard which must be corrected beforereturning the

unit to the owner.

harman/kardon Service Bulletin

Service bulletin # H/K2002-04 April 2002 Warranty labor rate: MINOR repair

To: All harman/kardon Service Centers

Model: AVR8000

Subject: Idle Current Adjustment Procedure

In the event you receive an AVR8000 with the complaint “The receiver is overheating, or the protection circuit is engaging, or intermittently shutting down after the unit warms up” the DC idle current should be checked and adjusted as described below. Top cover may feel abnormally hot to the touch.

Synopsis: Set DC idle current of output devices by adjusting five potentiometers

Specialized equipment/parts needed: Variable AC transformer (“Variac” type) to adjust and monitor AC line voltage. Two pin harness plug to connect DMM to idle current test points. Order hk part# 55212910NR.

Note: Unit that no longer functions when cool may have damaged components: output transistors, resistors, diodes, etc, in the output stage which must be replaced before performing adjustment so protection circuit is not activated.

1) Unplug any external connected cables to the AVR8000.

2) Remove the top cover, (18) black Phillips screws.

3) Locate the five idle current-current adjustment potentiometers (see illustration page 2). Facing the front of the AVR8000, they are located on the left and right sides of the unit along the top of the vertical PCB’s. They are also marked on the PCB’s “Idle-Adj.”

4) The white 2 pin Connectors (test points) and their related adjustment pots are referenced below. First, with the unit turned OFF, adjust with a small screwdriver so that all idle current pots are “centered”.

Test Point (Check with DMM) Adjust Idle current Pot

CP903 Affected by VR902 CP904 Affected by VSR902 CP922 Affected by VC902 CP923 Affected by VL902 CP924 Affected by VSL902

Do not confuse the idle current adjustments with the DC offset adjustment pots which are located directly adjacent to them !

5) Replace the top cover (no screws); turn unit ON. Unit should be connected to a “Variac” type (variable transformer) adjusted to 120VAC. Let receiver idle with no load, no signal input, and volume control at minimum (full CCW), for five minutes to stabilize the amplifiers.

6) Remove cover again. Plug in the two pin harness plug at first test point and connect to DMM set on the mV scale. Check and adjust AC line voltage to 120 volts again if necessary. Using a non-metallic screwdriver, adjust each of the idle current pots, one at a time, in the following manner: The final desired voltage at each test point is 10.5 mV, but you should arrive at this voltage by reducing a higher amount in 25% increments with each adjustment, with the final adjustment set at 10.5 mV. This adjustment should be made gradually in steps, so the amplifiers will have time to stabilize. Repeat this procedure at least three additional times, each time replacing the top cover (no screws necessary), and letting unit idle turned ON for at least five minutes between each adjustment. Monitor the AC line voltage and adjust to 120 volts when necessary.

7) If a wattmeter is available, total wattage drawn from line should be 165 to 170 watts at idle.

8) Replace the top cover and screws after the final adjustment.

Service bulletin # H/K2004-01 Rev1 March 2004 To: All harman/kardon Service Centers Model: AVR8000 Subject: DVD Surround Mode Switches to Stereo

W hen DVD soft ware is b eing m astered, the producer has the opt ion to choose w hich audio f orm ats are us ed, and the time intervals when they present themselves. For example, a typical DVD may utilize Dolby Digital 2.0 (2 channel) audio format i n the initial screen. A typical first screen may include menu choic es such as: Special Features, Audi o Setup, Directors C uts, and Play Movie. This remains on- screen until the user makes a selecti on, and normal ly would be “Play Movie”. At this point, the p roducer may decide to Dolby Digital 5.1. If this time interval is too short, as it is on a small number of DVD titles, the surround DSP process or i n ear l y AVR8000’ s may stay in Dol b y Di gital 2.0 ( s ter eo) , r at her than sw i tc h to Dolb y Dig i tal 5.1 when the prog ram b egins , even thoug h the fr ont panel i ndicators on the unit may imp ly 5.1 is in effect. In this condition, this will not be a tru e stereo mode and music information will be lost, and not added to the stereo loudspeakers.

In the event you receive an AVR8000 A/V receiver with the complaint: “When I play a DVD with a player that’s connected to the AVR8000 digital inputs, the receiver stays in stereo mode once the DVD starts playing, when it should be playing Dolby Digital 5.1”, perform the modification below:

Synopsis: Change IC100 on the DSP sub-PCB. CAUTION: IC100 is an electrostatically sensitive device and can be damaged by careless handling; follow

proper static control procedures to prevent damage to the module.

1) Unplug any external connected cables to the AVR8000, particularly the POWER cord.

2) Remove the top cover, (18) Black Phillip s screws.

3) Locate and remove the metal shield located between the PCB’s and the power transformer (See figure 1); remove th e (2) bottom Phillips screws first. A long shaft Ph illips screwdriver is required, and magnetic blade preferred. Then remove the (2) Phillips upper screws; remove the shield from the unit.

4) At the rear of the AVR8000, remove the (2) black Phillips screws holding th e IR Remote PCB t o the rea r cover; set the PCB aside, with cable st ill attached; remove the (9) black Phillips screws ho lding the V ideo PCB to the rear cover. (See figure 2)

5) Remove the 7 conductor amber colored Molex plug (CP602) from the right side of the Video PCB.

6) Remove the fina l t op (2) Phillips screws holdin g the Video PCB on.

7) Push the narrow vertical connector PCB away from the rear of the Video PCB, disengaging it from the Video PCB (and the Input PCB).

8) Lift the Video PCB, with ribbon cable attached, out of the unit and set it aside.

9) Carefully unplug and remove the IC100 module, pulling straight up; the connector and pins are on the left side so more effort is required there.

10) Replace IC100 with h/k part# 55229550DPS; CAUTION – after replacement, make sure module is inserted correctly – On PCB the lettering “TOP SIDE UP” should be facing the rear of the unit. Do not force into place or bend pins, and make sure the socket is engaging all pins correctly.

11) Reassembly: follow instructions above in reverse order, assuring module, screws, molex connector, vertical PCB, and shield/support is replaced. The metal shield has two “locator pins” at the bottom; make sure they are replaced in the holes designed for them at the bottom of the chassis. Replace IR Remote PCB and all screws at the rear of the unit; replace cover. When replacing the screws, use caution and do not over-torque as you may strip the plastic receptacles.

12) Test the AVR8000 by re-connecting to the DVD player and playing the exact DVD disc that the problem had occurred in, and assure the receiver stays in Dolby Digital 5.1 when the program is played.

harman/kardon TECH TIPS

Troubleshooting tips and solutions to common service problems

For models: AVR8000 TIP# HKTT2002-02

Complaint:

Remote control seems to have stopped working

Solution(s):

1) Remove the batteries and confirm they are not weak or defective. If battery voltage in either battery is less than 1.4 volts, replace both batteries in the Remote Control. Assure batteries are inserted correctly.

2) If the Remote Control still cannot control the AVR8000: if available, see if the AVR8000 zoneII, or another AVR8000 or AVR7000 remote control will operate the basic functions on the receiver. If the AVR8000 does not respond, skip to step #6 to perform a system reset of the microprocessor.

3) Use a InfraRed detector/test card to see if there is an output from the Remote Control. If there is no output, order new remote control, h/k part# BE10A00.

4) If an output is detected, but it still will not control the receiver, follow steps a-e to reset the microprocessor in the Remote Control. Note, however, that once it’s reset, all special commands or codes that were entered will be erased, and the Remote will be reset to factory default. You do not have to point the Remote Control at the receiver during this procedure:

a) Press any of the Input Selector Buttons and the 0 Button at the same time until the Program/SPL Indicator

begins to flash amber. b) Press the 3 Button three times. c) The red LED under the Input Selector will go out; the Program/SPL Indicator will stop flashing and turn green. d) The Program/SPL Indicator will remain green until the remote is reset. Note that this may take awhile,

depending on how many commands are in the memory and need to be erased.

e) When the Program/SPL Indicator goes out, the remote has been reset to the factory settings.

5) If the Remote Control still does not control the receiver, (and other Remote Controls are successful), order new remote control, h/k part# BE10A00.

6) If any h/k Remote Control mentioned in Step #2 will not control the receiver, follow steps a-c to reset the microprocessor in the AVR8000:

a) Unplug the unit from the AC wall outlet and wait at least three minutes. After the pause, reconnect the AC power

cord.

b) Make sure the unit is in Standby mode by pressing the System Power Control Button; the unit is placed in a

Standby mode, as indicated by the AMBER Indicator.

c) Next, press and hold the Tone Mode 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. NOTE: Resetting the processor will erase any configuration settings that were made for speakers, output lev els, surround modes, digital input assignments, and the tuner presets. All settings for these items must be reentered.

7) If the Remote Control still does not control the receiver, follow the instructions on Page 3 to replace the AVR8000 IR Receiver/Sensor. Optional: You can check for an output at the IR Output jack at the rear panel of the receiver, when a Remote Control command is attempted. A connection can be made from a “test cable” consisting of a 1/8” mono mini-jack plugged into the REMOTE OUT jack, attached to an oscilloscope at the opposite end.

Figure 3

This view of the unit shows the connections from the 3-channel amp assembly to the main PC board (See Figure 3). Note that 3 connections on Main PCB board are the same size, and use the same color

wires. These connections CAN BE INTERCHANGED if not careful and serious damage can occur if the technician is not careful.

Figure 4

Be careful not to break any of the contacts, wires, or sub assemblies. The PC boards shown in the above picture (Figure 4) are all interconnected through four separate extender boards. If you look carefully at the stacked PC boards, you will notice that when they are not in the chassis with the rear plate attached, they are NOT supported at one end. This may cause a Short to occur if one PC board touches another while the unit is being serviced.
