Sanyo Multiverse Projector Model PLC-SU50S Problem

[irvy101]

Hey guys. I have a sanyo projector. I hope someone is familiar with it. I'm having a problem displaying an input image.

On the the back of this projector is a switchable terminal (computer in 2 / computer in / monitor out). Hence this terminal can be switched to use it as either computer in or switched to monitor out.

It has been set to monitor out and I can't get it changed back to computer in. The manual is contradictory as far as I understand it. It states -

When choosing an input signal select either computer 1, computer 2 or video. To use it as a computer input using the scart cable select computer 2.

It then adds that if the option for computer 2 is not displayed (which it isn't) it is because the switchable terminal is set to monitor out.

So my problem is that because it is set to monitor out, the option I require (Computer 2) is not displayed. Therefore how can I switch the signal from monitor out to computer in?

Selecting Computer 1 doesn't do anything. Computer 1 is for a DVI connection anyway. Thanks guys.
