Hi Javis. This is perfectly normal ! This mode change is done because the receiver auto detects the digital audio signal and sets the receiver's DSP to decode the signal correctly. You can go into the OSD menu to bypass the auto detection of it, but it's not recommended at all ! You're getting the best audio quality by doing so. Thanks ! cheebster.

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

Followup on higlider's problem. Now it has to be turned on ten times before it stays on. Email from Harman Kardon only suggests taking it to an authorized repair shop. It is clear that it is not from speaker short or overheating, because it only happens when the rcvr is cold.

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.

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: Harman/kardon avr 247 no audio or LED display on the reciever

I've had the exact problem. HK in the states is no help, you need to deal with a company in Montreal (Jan Industries). Regular techs are unable to fix it without schematics that only authorized dealers have and the manufacturer. This problem happened to me just after 2 years and outside warranty. I've bought a Yamaha today.

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.

How do i fix a noise problem on 6.1 avr 135 ?same trouble occur on alls channels,a high frequency sound disturbing listening.neither inputsi used(cd-dvd-tape)


There are many reasons this may happen, but without having the unit on the bench, it will be hard to tell. It may be oscillating, which would make that sound. I worked as a Technical Support Specialist for Harman Kardon. If you are interested in repairing your HK, please visit my website at audioserviceclinic.com. Thank you.

HARMAN KARDON AVR 130NO SOUND FROM SUB WOOFER


Register and download the manual for free at retrevo.com

http://www.retrevo.com/support/Harman-Kardon-AVR-130-Receivers-manual/id/386ci155/t/2/

The receiver must KNOW it has a sub and you must decide how bass is managed among all your speakers and set up relative levels.

Harmon kardon 745 displays "unlock" no sound for tv or movies


I also had this UNLOCK message on my Harman Cardon AVR 130.
The reason for this error was - in a hurry I've plugged the optical input into optical OUT! Double check that your connections in the back are correct and hopefully it fixes your problem.

Cheers,
Sergey
