Hi,<br />I have a problem with the NEC 9PG plus that we have at work. I cannot access any of the operate/adjust menues, either from the back panel of the projector or the two remote controls. It will however respond to picture mute and position commands. At the moment it is linked to an ISS6010 switcher but disconnecting this and running directly into the projector from computer via the RGBHV input still doesn't enable access. This seems to have been a gradual loss of function as I used to be able to access the setup menues, adjust the position and convergence but not store the settings. Any thoughts as to the cause and solution. Regards, Simon.
