Need help locating Schematics

[Rip01]

I need help locating the schematics for POWER SUPPLY-DC PB67 Part code 3N100831. For the Nec vt580 projector. I tried Google and the links provided here by Steve. By the way Thanks Steve and no luck. At any rate any help would be appreciated.

Is the NEC VT580 any way comparable to the VT540?

It may be that there are enough similarities that makes this download useful:

Kellys_eye thanks for the reply sadly they are not similar.
