I already did a factory reset.
Yeah, I know what you mean, don't know how it's stuck on zone 2.
Let me mess around with the zone 2 stuff in OSD some more...
Headphones do work when watching a DVD or CD, just not in TV mode...
If nothing else, page 78 of the online manual shows how to do a factory reset.
Looks like section 3 of your OSD (Option Menu) has Zone 2 controls, but not necessarily an on/off option. Looks like you can select whether the speaker B terminals go to power speakers in zone 2 or additional speakers in zone 1. Also whether the zone 2 speakers are powered by the yamaha or if the pre-outs go to an external amplifier.
The double star button on your remote sets it to zone 2 control. The manual says it goes back to main zone control after 10 seconds though, so it doesn't seem like your remote would be "stuck" in zone2 mode.
I guess try messing with the zone2 controls in the options menu?
Do headphones work if you plug into the receiver?[/quote]
