If you open the document feeder when you turn it on, do you see the scanner mirror moving or the exposure lamp turning on?
Machine runs on 110/ 220 down to 24 volts.

My guess if only fan works, could be a bad main or power board.

Machine is as good as dead. No mirror movements, no exposure lamp. When I checked the power board output is giving 24v,3.9v,5.1v etc

Any previous error code on the display?

Might be a display panel or RAM DIMM?
As a test, try another HDD., see if the machine gets POST and the display comes on.

Remove covers and use a flashlight to see the wiring and boards inside, in the past I've seen chewed cables and mice pee-damaged boards, if it's your case not worth a repair, too much work, too much money and too much risk to your health...just a little advice.

firmware on this machine was tricky needed to use CF card, and small size 128 card large cards did not work and some brands worked some did not. Usually was it was the copier with the fax boards on them that we would see it , always had fingers crossed on on update until company got the Buffalo brand cards recommend by Mita
