Xerox Phaser 7800 Green screen and reboot

[copyTcat]

We got a Xerox Phaser color 7800GX at client location that has green screen with xerox logo attempting to finish boot process and than machine reboot again and again. (Boot Loop)
We suspect the SD card got issue but not sure. Is there a way to reload new data or image on the SD card or should we look into main board?

Had a similar issue with a Xerox phaser a while ago, not a Xerox expert but as it boots it seems to run up different parts of the machine in a specific order, it got to a certain point and then dropped and rebooted as you described, turned out to be the power supply dropping out under load when a specific component kicked in. Removed P.S.U. and found visual signs of damage. New P.S.U. fixed it

Good luck

You can reload the contents to the SD card with a disk image application. I have the SD image available.
