Check your audio settings on the main menu of the receiver. The audio input should be set to "auto" Next, make sure you don't have the unit in "6 channel input" mode or "direct" mode. This is usually a small button on the front panel. If you check all this and you still have a problem, post a comment and I will help you troubleshoot some more. Hope this helps

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.

Will not retain presets


Many times a capacitor is used in place of an actual battery. On Harman Kardon receivers this component is on the front side circuit board behind the receivers external display. Harman Kardons website provides the actual location and part number if you dig around for the service manual PDF.

No sound in hdmi mode unlock flashes on display I get sound in cd


Its asking your permission to unlock the setup menu. When you hit setup, and it says "unlock," you have to hit one of the navigation arrows on the remote control. Once you have unlocked the menu, you can assign the audio to that HDMI input.
