Sony receiver no longer remembers last audio source

[Mike Foss]

I have a minor but irritating problem with a Sony STR-AV270
receiver. When powered on, it no longer remembers the last
audio source when it was last turned off, but instead always
defaults to the FM tuner. It never used to do this until recently.
What's irritating is that I don't use the receiver for FM audio,
and no antenna is attached to the unit. So I often wind up
getting loud static in my headphones before I realize I need to
manually switch sources.

If the fix is easy I'd like to handle it myself. It's an old model
and isn't under warranty anymore.

Thanks for any info.

Maybe a backup capacitor - other than that I got nothing. No service
bulletins on this.

Sounds like the memory back up battery has failed. Common with age. Might
be a Ni-Cad or capacitor.

it's hard to say.
you could have some bad Flash memory if that is what's
holding your settings?
you could have an on board Ni-cad better/Cell that needs
replacing because it will no longer accept a charge or you
could be using one of those high dense button caps that needs
to be replaced!

Probably the battery.
