[Dead] Konica Minolta BIZHUB 211 - dead

[Guest]

Hello everybody! At first - sorry for my bad english.

I have a big problem with BIZHUB 211. When I turn ON the machine, turn on the machine I hear the motor rotating but nothing on LCD. Scanner lamp doesn't lit, and so LED on lid. Fan on left side of the machine works all the time.

When I connect machine via USB, Windows says "Unknown USB device" or "Device malfunctioned", so I couldn't upgrade firmware.

Power supply seems OK. There is 3.3V, 5V and 24V. I doubt that the GDI board is faulty, however I haven't found on the internet where I could get a new one.

If anyone had a similar problem, I'd like to hear his experience. Thanks in advance.

have you ever checked or replaced the MFP board and printer control board? Try it. Something wrong with them.

Thanks.

Where could I get or buy them? I couldn't find it on Internet.

edit: If anyone has an electronic scheme of bizhub 163 or 211, I'd love to share it with me.

Thank you
