Panasonic Projector

I have a classroom installed with a Panasonic PT-LM1E projector, it is wired through to a socket on the wall and has a laptop plugged into it.

The problem i am having is that when it is turned on the position of the screen on the projector display is too far to the right, the position can be adjusted to the correct one, but then when the projector is powered off it resets back to the (wrong) position.

Anyone got any ideas/suggestions here?

Has the projector got an automatic keystone / alingment? Could be that this is over-riding any settings you make.

Yes it does have a automatic keystone alignment, tried turning this off, there were 2 options for auto this and that so set them both to off and this seems to have cured it thanks!
