Sahara S2000 Projector problem, need to access the service menu

[SiE]

I have a Sahara S2000 projector and the image has started to ghost slightly. Apparently its down to the lcd timing but I do not know how to get the service menu up to change it. I found on another site the button combination down up left right but this seems to be for another model. Anybody got any ideas on how to access the menu?

I cant believe how hard it is to get this service menu up.

Sahara projectors are shit, we had 48 in school and all but 6 had to be returned, its no wonder they went bust.
The up down left right is only to get to the lamp reset.

good luck trying to get the info.
