Hi all,

I'm wondering if a service manual for the bizhub C450 with detailed schematics (for the pcbs, not only the wiring diagrams as shown in the manuals we got from Minolta) exists?

We have a machine here which actually works fine, the display reacts to touch, but does not display anything. Before you ask, the backlight is fine, it's actually on.
I would like to trace down to the point where the data stream to the display processor gets lost to determine which board to blame. The fault probably occured when our trainee tried to clean the ADF and shorted out the 24VDC to some other wire...

with kind regards
Stefan
