crazymao,
I thought at first it may be in a demo mode, but I don't think that's the case. You can try to hold down the menu button for 10 seconds to see if that doesn't fix the issue.
If not, I would fill out a repair request ticket, and you can do that here:

I have a SyncMaster 2693 Samsung TV. Whenever I turn it on, the MagicBright appears in the bottom left corner of the screen and goes through all the options. Whatever I do, turn it off, unplug it, its still there. Its driving my crazy so any help will be greatly appreciated.
