May be this diode is the solution of reversed polarity problem on Minolta DiMAGE Scan Elite 5400?
Is that diode shorted?

Thank you, in the mean time I found the pdf in attach.
I could test it only on the circuit, on both directions is 0,035 V with diode tester VC303.

I've unsolded and tested it with VC303:
- diode test shows 195 (forward) and 1 (reverse)
- position 2000 k Ohm shows 106 (forward) and 932 (reverse) Ohm

Minolta Dimage Scan Elite 5400, as said before in the posts inoperative because of accidentialy reversed polarity.
Does somebody have the same scanner with mechanical issue and with good electronic components? I'd buy it. I'd also buy only the main electronic plate of scanner.
