Hi, I bought a Samsung DLP 4663W a couple of weeks ago and find the picture to be excellent. Did have the whine noise from the color wheel, and the service department came and installed the new light engine.
Now, when you look at the TV with a 4:3 source, you can tell that the entire image is tilted very slightly, so that a horizantal line going across the screen is a little higher on the left of the screen, than on the right of the screen.
The amount of horizontal tilt is slight, about 1/4 inch or so. It was also slightly vertically off.
I entered service mode and was able to use the horizontal and vertical adjustments to get the picture centered, but could not find a "horizontal tilt" adjustment. Is there such a control? Or should I have the tech back out to adjust the physical "level" of the light engine? I'm suspecting that it may not be sitting perfectly level in its slot.
