Samsung DLP Discrete codes are in firmware versions 212 or later. To check the firmware version of your set you must enter into the Service Mode using your remote. Start with the TV turned off. Using the remote, enter the following sequence; Mute-1-8-2-Power. The set will come up with a service menu. The S/W Revision will be the last three numbers displayed in red near the bottom of the screen. To exit the Service Mode, turn the set off for about 1 minute before using again. Hmmm...I wonder what the other Service Options do that are displayed on the screen.
