Harman Kardon AVR 7000 loosing memory

My HK AVR 7000 looses memory after a few days and returns to factory default settings. Everything in memory is lost, e.g. radio presets, audio settings etc. I have tried the cpu reset method from the users manual but that does not help. Any suggestions?

This is what's in the AVR7000 service manual:

Subject: Backup Memory on AVR/DPR/HK series receivers.
In the event of the complaint: “the receiver is losing its memory (any programmed system settings)
when the unit is turned off, or after the unit is unplugged (briefly*)”:

Check and replace:
Model: AVR7000
Designator: C730
Location: Front PCB
Description: 0.047 Farad 5.5v capacitor
Part number: # P10790-ND or # J3432147324X

I'm having the same problem and this is how far i got so far. I don't kwow how to get and replace this part.

    The front PCB is the board that is in the front display of the receiver. And it is kind of difficult to reach. I have a friend that has removed the front PCB en replaced the part before. So i'll bring my receiver to him and see if he can fix this.

You can check all your speaker wires for shorts, as well as try the reset to factory defaults procedure found in your owner's manual, but I doubt this will resolve your issue. If you require more assistance, or would like to inquire about repairing your HK, please visit my website at audioserviceclinic.com, and contact me there. BTW, I worked for Harman as technical support for all Harman, JBL and Infinity products. Thank you.

I have the HK AVR 65 Amp. After power failure I loose all my preset settings.


Hi, there is a super capacitor on the front panel PCB (C 906), value:
0.1F 5.5 V.
Just replace it, and hope it will resolve the problem.

No gots. The 3485 is pre-digital stereo-only.

From the manual, page 19

"You may have observed that the HK 3485 is not equipped with digital audio inputs or surround sound decoding. If you prefer the complete home theater experience, you may wish to consider purchasing a fullfeatured Harman Kardon AVR Series audio/video receiver. However, we hope you will find that using a DVD player with the HK 3485 in smaller settings, such as a bedroom or den, surpasses the audio performance of most televisions, including those with onboard stereo speakers."

Settings lost when powered off. My Harman Kardon AVR 300 forgets all its settings when powered off. All radio station settings are lost, but also the input selections eg. cd=optical 1 etcetc. I guess there...


Most of these HK receivers have a 3.6v rechargable battery on the front panel board. If the battery dies, you lose memory when it is turned off/unplugged/power failure. The battery is soldered on the board. Not replaceable by the user unless you are a tech. It should keep memory if left in standby.

Harman Kardon has a great website on Ebay and they sell just about everything you can think of, new and remanufactured there. If you don't see this remote advertised just click on something they are selling and call them directly. I bet they have it in stock and will ship asap.
