I guess my question to you is have you tried recalibrating your monitor or double checking to make sure that all the settings are correct for your region?

In my dealings with Yamaha, their customer support (in the U.S.) has been very good and definitely a lot more responsive than anything I've gotten from Denon or Sony. Then again, I've never had a defective unit from Yamaha either.

FYI, the customer support is handled by the regional distributor for each country and I would guess that Australian models are somewhat different than the U.S. models with different power supply parts, tuners, and probably video components as well since Australia uses the British PAL broadcast standard.
