I'm in the same situation, except my receiver is an AVR65. Can anybody help me with this?

Need to replace the "backup" capacitor that keeps enough of a dc charge to back up the tuning data. It is usually rated at .047 to 1 milifarad(not micro) & located close to the processor & or display Ic---very common failure among all brands of receivers & a great gravy repair Smile
