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:
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.

I believe it is actually a memory capacitor that has to be replaced. It is soldered directly into the board and requires quite a bit of know-how to replace.
Hope this helps,

I'm having the same problem only difference is I baugh my product new, i love my reciver when it works I'm convinced the product is built like everything else these days cheap with no pride, designed to malfunction so hard working Americans like myself pull out of pocket to replace the product being a different brand or what, cuz large corporations repeatedly screw the little man time and time again for years and believe me folks it's only gonna get worse if the little man sits back and does nothing.. I personally do NOT recommend this product costumer service with this product also burns my as# it's a waste of time on your behalf.. Thanks for reading hope to hear from many of you.
