SOURCE: My Harman Kardon receiver (

I used the live chat and the problem was resolved.
Usually the problem are strands of speaker wires which cause shorting and protection shuts off the receiver in order to prevent damage. There was one speaker that I repositioned recently which was causing shorting. I twisted the wires and tightened them in place and my receiver has been working w/o a glitch. I was lucky that I did not have to check all the wire strands on the receiver and all the speakers.
Problem solved and I learned valuable lesson.

SOURCE: can I conect harman Kardon avr 230 to apple tv

Yes, although it (AVR) does not support HDMI only component video.

Connect the audio to the receiver and the video directly to the TV if you have inadequate video inputs, or want to take advantage of the HDMI.

SOURCE: AVR amber light will not return to blue after

There is an internal reset switch mounted on the transformer board. Open the unit, look at the boards attached to the transformer, the pushbutton is facing up. Measure the voltage on the 2 pins of the switch. If it is a logic low, the switch is partially shorted. Replace the switch or just cut the jumper wire just below thw switch. When this switch fails, it constantly resets the receiver and stops it from powering up. It does not fix a protection mode problem.

HOW TO RESET HARMAN KARDON AVR70


Hi, Try this. Hope this helps and I have the link here to the manual.
Processor Reset
If the AVr behaves erratically after a power surge, first turn off the front-panel
main
power switch and unplug the Ac power cord for at least 3 minutes. plug the cord back
in and turn the AVr on. If this procedure doesn't help, reset the AVr's processor as
described below.
note: resetting the processor will erase all user configurations, including speaker and
level settings, and tuner presets. After a reset, reenter all of these settings from your
notes in the Appendix worksheets.

To reset the AVR's processor:

1. press the front-panel Standby/on switch to place the unit in the Standby mode (the
Standby Indicator led will turn amber).
2. press and hold the front-panel Standby and memory/folder buttons until the reSet
message appears on the front-panel message display.
3. press the memory/folder button again to reset the AVr's processor.
If the AVr does not function correctly after a processor reset, contact an authorized
harman
kardon service center for assistance.
to locate an authorized service center,
visit our web site at www.harmankardon.com.

No cengter display or sound


I also have the problem of no center display but I do have sound.

On my avr 7000 I am sure that the display is not functioning but on yours try holding the middle select button for three seconds as in the manual this is how you turn the display brightness back on.

I have no clue why they have made it able to be turned off lol

Hello. I get no sound out of my AVR 7000 Receiver. No cables behind has been touched in the past. I'm trying TEST TONE, and everything seems normal in the display, but still no sound. I use Preout a NAD...


You don't say if all speakers are silent or just the ones to the unspecified NAD power amp. Do ANY speakers work regardless of which device powers them? Could the NAD be the problem?

I have a harman kardon avr 745....looks frozen


My device is AVR 645, but AVR 745 has the same power regulator board and you could check, if the problem is there.
(AVR 645 volume blue light was not pulsating)
When device is turned on, it shows all display indicators,
no blue light on volume button and no response to any remote or front panel buttons.
Reason for failure:
No 3.3V and 5VD voltages.
I checked bridge rectifier D701 on power regulator board.
One of the diodes was shorted. Also fuse F702 was blown.
Original D701 is KBU6G, but because regulator board is a bit difficult to get out, I decided to use KBU8G. The only difference is Amps rating 6A versus 8A.
Be sure to use SR-5-3.15A fuse to replace F702 and use heat sink paste (you know where) when board is reinstalled.
There is large heatsink in the middle of the receiver. Power regulator board is mounted on the right side of that heatsink. It is down there near the front panel and to get it out you most probably first have
to remove two PCBs hindering access to some regulator component screws. Here are pictures to clarify situation:

AVR 7000 audio/video receiver


Harman kardon amplifire are known for that.specially AVR 7000
but sometimes this comes from poor wiring and using a wire that will not conduct better sound. Remember your wiring is very important.you may think your wiring is currect, better to double check. even if your connection is ok and the wire you are using are not better to produce quality sound you will not get sound from every speaker.

good luck
