Be sure that once you have changed your player settings to the preferred settings,
that you are power cycling the player with the remote or the power button on the front of the player.
If you are cutting the power from the outlet or surge protector, your settings may not be saved,
and thus the next time you power on the player, the default settings take over again.
Also, make sure that you are using the setting inside the settings menu to control what volume you want the player to power on at.
If you do not change that setting, no matter where the volume is when powering off the player, it will turn on at full volume again.
If neither of those scenarios describe what may be happening to your player, then there's a good chance it may need serviced by Oppo.
