I recently purchased a Samsung hlp5663w 56" DLP off of craigslist and after bringing it home I found it has this black line on the left. The picture looks great and the bulb has ~1800 hours on it along with a color wheel that was replaced last year. I tried going into the service menu to see if there is some settings I could change but I don't really know what I am doing. It seems like the projector gun is slightly off and is cutting the picture off on the right by a inch or two. Here is some pictures to illustrate the issue. Any help would be greatly appreciated!
