I have an Epson EMP TW700 projector and the top left and bottom left side of the image is going towards the centre left, there is a setting/button to adjust the top left and right and another button to adjust the bottom left and right sides but there is no setting to adjust top/bottom left. If I use either of the buttons to adjust the top or bottom it is still out of being plumb. When I disassembled this projector to fix a different problem I must of made things out of alignment but I dont know which thing or screw to adjust.
The picture below is an over exaggerated example but this is basically it.
