Re: LG and Zenith Plasma Type Display
Press and hold menu on the remote control until the menu screen dissapears. Release the menu button. A screen should appear asking you for a password. The password is 8741. This reveals a expert viewing mode. You have full picture controls and RGB cuts and drives. When this mode is calibrated, the User menu has a new Expert viewing mode that the user controls are grayed out. This mode is calibrated by input, so one calibration per input that is used.
