Service bulletin # H/K2000-06 April 2000
Warranty labor rate: MINOR repair
To:
All harman/kardon Service Centers
Models: AVR7000
Subject: Switched AC Accessory Outlet Dead
The Switched AC Accessory Outlets on the AVR7000 are used to power up any low-wattage
device when the AVR7000 is switched on with the System Power Control. Ordinarily this means
CD players, DVD players, Tape Decks, etc. or any device not exceeding 100 watts per outlet.
These accessory outlets are not intended to be used with higher-power devices such as television
sets, power amplifiers or powered subwoofers.
However, under some circumstances, even the use of a recommended device connected to the
AVR7000’s Switched AC Accessory Outlets may briefly exceed the current rating of the internal
1A AC accessory fuse, and blow the fuse.

In the event you receive an AVR7000 with the complaint “The switched AC accessory outlet
at the rear of my receiver is dead”, perform the following procedure:
at the rear of my receiver is dead”, perform the following procedure:
1) Remove the top cover, (16 Black Phillips screws).
2) Locate F451, a 1A GMC (5 x 20mm) fuse at the rear corner of the unit, where the AC power
cord enters the rear cover. Remove it and replace with a 3.15A GMC (5 x 20mm)
Slo-Blo fuse, h/k part# 5508302735 . Original fuse can be extracted with a pair of long-nosed
pliers.
3) Replace the top cover.
4) Test the Switched AC Accessory Outlets by connecting a low power device, such as a CD
player, DVD player, or Tape Deck and assure the unit powers up normally when the AVR7000
System Power Control is switched on.

TECH TIPS
Troubleshooting tips and solutions to common service problems
For models: AVR7000
TIP# HKTT2000-01
Complaint:
The Remote Control has stopped working for the AVR7000.
First Check:
1. Make sure the batteries in the remote are installed correctly. (Plus and minus to correct terminals)
2. Make sure the area between the remote control and receiver is not blocked by some object, and the
2. Make sure the area between the remote control and receiver is not blocked by some object, and the
distance is no more than 15 feet at an angle no greater than 30 degrees from the front of the receiver.
3. Make sure strong lighting is not directed towards the IR sensor of the receiver.
4. Press each button on the remote and verify proper operation.
4. Press each button on the remote and verify proper operation.
If these steps are taken and remote control still does not function properly
−
Probable Cause:
Factory-supplied batteries.
Solution:
1. Remove the batteries from the remote. Leave batteries out of the remote for a minimum of three minutes.
This ensures the internal capacitors discharge, allowing the CPU in the remote to re-boot.
2. Reinstall new alkaline batteries (major brand recommended).
3. Press the AVR button and the Mute button at the same time until the red light illuminates under AVR.
4. Enter the numbers 0-0-1 on the numerical keypad.
5. Press the AVR button again.
3. Press the AVR button and the Mute button at the same time until the red light illuminates under AVR.
4. Enter the numbers 0-0-1 on the numerical keypad.
5. Press the AVR button again.
Test the remote control. It should be functioning properly once this is completed.

AVR7000 IDLE CURRENT ADJUSTMENT
1) 2-CH AMP and 3-CH AMP sections should be adjusted when they are intact on the Heat-sink
2) Initial warm-up and test condition: 1Khz - Signal input, SPKR-OUT(8ohm load), 5CH All driven
3) Warm up 3 minutes in step 2, then remove input signal
4) Emitter resistors - connections across MPR901,904, MPR907,910,913 as follows:
adjust voltage to 26mV ± 5mV connected across opposite ends of resistor leads.
5) Potentimeters to adjust are as follows:
