If you are willing to get into the service menu, there are a series of gray scale displays you can step through. Be aware that making changes in the service menu could really mess up your set. so be careful.
That said, here are the steps to get to the gray scale displays, taken from other posts in the D62U/D64U forums.
1) unplug the set.
2) hold input and volume down (on the set not the remote) simultaneously while plugging the set back in. Hold these buttons until a K symbol appears on the left side of the screen.
3) When you see the K, hold down both channel-down and volume-down(again on the set) until the service menu appears
4) at this point press #'s 1 through 6(on the remote) to get the various gray levels. DON'T MESS WITH ANYTHING ELSE. It is possible to destroy the set from within this menu.
Turn the tv off and back on again to return to normal.
