Question about Harman Kardon AVR 100

1 Answer

Harman Kardon AVR 40 no sound

Harman Kardon AVR 40 was working just fine for quite a while, and then about 3 or 4 times in a row, when I switched to the audio channel that I wanted (CD or TV usually), a strange sound came through the speakers and then nothing.  Now no strange sounds come through, and it does nothing at all.

I've tried all the inputs, all the speaker outputs, taken the cover off and vacuumed/blown the dust away, and tried to see if there were any obvious problems.

Any other ideas?

    Yeah i have a Harman Kardon Avr 100 and when ever i turn it on it just turns off automatically. I did that twice and then about in the back center of it ( if you look at it straight down) something went pop then a little bit of steam came out. so i'm guessing it's the fuze.

Check the fuses - there may be one inside the box as well. May also be a bad transformer. You can get a multi-meter at Home Depot and lookup how to check the power at the transformer.

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
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
kardon service center for assistance.

I have a Harman/Kardon AVR 325. Left speaker not working with TV

How is TV audio (from the cable box) getting into the Receiver? If digitally, you wouldn't be missing any one channel on a connection malfunction, you'd lose them all. If analog, swap the channels around to isolate the problem (and reconsider using digital).

I have a Harman Kardon AVR 235 Receiver that go's into Protect

To avoid making the avr go into protect mode when you power up your Hafler 4000 that is connected in the avr's pre-out, you must power up the set up in the correct sequence.

1. Turn off your avr
2. Connect Hafler 4000 to the avr's pre-out it it is not yet connected
3. Turn on your Hafler 4000. The avr will not go into protect mode becasue of the transients from the Hafler because it is still not powered on.
4. Turn on you avr. There should be no more transients from the Hafler at this stage unless it is not functioning correctly, so the avr shouldno longer go into protect mode.

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 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

Harman Kardon AVR 120 turns off by itself after normal work for about 1 min

Do you get an indication on the display where the point of failure might be? It would show up on the LCD speaker diagrams just before shutting off.
