my diamond pro 900u will not do a geomentry reset

[prc00l]

I was bored/curious/stupid and I was messing with my mitsubishi diamond pro 900u settings and I can't seem to restore it to the factory settings. Whenever I try to reset it it reads: Geomentry Reset User timing cannot be reset. Any ideas? I tried doing this with the computer turned off too but the monitor control screen won't come up. Thanks, i'm stumped
