Re: Hitachi Plasma Type Displays
* With the TV turned ON
* Press and hold the “MENU” button on the TV.
* Then press the MENU … 8 … SELECT buttons on the remote.
* To exit, press the “MENU” button on the TV or the “EXIT” button on the remote control.
** It should be noted that on some plasma units, there are actually better grayscale controls in the user menu than in the service menu. Look to the user menu first for grayscale controls listed under titles like “white balance”
