If the 7 segment stops at 6, the RAP starts with checking/replacing the SATA cable, replacing the HDD and finally replacing the SBC PWB.
no, with your information about the 7segment display, I could find out, that 12 V Supply of HDD is missing. 5 Volts are measureable. 12V are not. Is this coused by Mainboard or is this direct from Voltagesupply?
This could mean the Mainboard (SBC PWB) is defect. Should be a fuse for this voltage, can not see any?
If there is no fuse, i think I have to scrap the machine. Bad expierience with xerox tec with first contact.
Thanks for your help!
is there any way to find out where the 12 V for HD-Drive comes from. So, the question is: Do i need to change Power Supply or MainPCP?
Next Point would be, where can i get this part as used one?
Thanks for your help?
