Hello, I have a Onkyo TX SR 604 e and every time I disconnect the main power it looses it's memory and all the settings. I've tried a factory reset, but it didn't help. It still looses it's memory. Is there any way of repairing it? Can anyone help?
Change the C704 memory back-up capacitor.
The capacitance is 0,22F / 5,5V.
