Re: Cap. plague in Minolta DiMAGE Scan Elite 5400?

Got scanner with good plate and now it works ok.

Re: Cap. plague in Minolta DiMAGE Scan Elite 5400?

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.

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

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....

Does anybody recognize the characteristics of schottky diode 34 30 on the picture (red arrow)? How could I test it?
May be this diode is the solution of reversed polarity problem on Minolta DiMAGE Scan Elite 5400?...

Hi all,
I bought used Minolta dimage scan elite 5400 and it was ok. Then I accidentaly reversed polarity and after that I cannot switch it on, no lamp blinking.
After reading the article of BGUERBET at this forum I opened the scanner's casing but cannot see any damaged element, also the mentioned capacitor is ok for me. See my image.
As I'm not an expert could someone say me what to do. Is this the end of scanner's life or is there any chance to repair it.
Thank you for your reply
