Hi I am having a problem with a sony cpl cs2 projector, it displays a start up image on the wall but I am not sure how to project my slideshow onto the wall. The operating instructions are missing. The start up box pops up when the pc boots up but the options do not appear to give the options to project the image from the computer to the projector - then to the wall.

Make sure the connection from the pc to the projector is secure, also make sure the display settings on the computer are set to extend the desktop onto the projector, and that the projector is set to pc mode.
An overhead projector is a very basic but reliable form of projector. The overhead projector displays images onto a screen or wall. It consists of a large box containing cooling fan and an extremely bright light, with a long arm extended above it. At the end of the arm is a mirror that catches and redirects the light towards the screen. An overhead projector can be used to enlarge images onto the screen or wall for audiences to view.
does the "lamp/cover"-led light up? i had the same thing happening, the lamp either broke or is about to break and the projektor won't turn it on again to protect itself. if its very urgent, open the projector pull the lamp out and put it in again, it might work for 1 or 2 more times, but it is very likely to explode (usually not breaking the projector but for sure not good for it).
IF I understand the problem from the limited info in your question, the problem is a distorted picture on whatever surface [probably a wall, or screen] onto which the image is projected.
With all lenses, the axis [centerline of the lens projected] MUST be absolutely PERPENDICULAR [in both the vertical and horizontal planes] to the perfectly plane [flat] surface onto which the image is projected.
IF for example, the projector is mounted in a rear corner of the room, and the camera is aimed downward and to one side to project the image on the center of the opposite wall, or a screen located there, the image will be distorted. It will be larger on one edge [fartherist from the lens] and smaller on the opposite [nearest] edge.
If it is non-perpendicular in only one axis, then two opposite edges will be different lengths, and if out of perpendicular in two axis then no edges will be the same length.
The solution to this problem is that the center axis of the lens must be perpendicular to the surface projected on, in both vertical and horizontal axis.
