Xerox WorkCentre 7835 does not exit energy saver mode

[Detonation]

Machine is on 073.010.068.33100 software that was clean installed using altboot. All machine functions work fine, but when it enters energy saver mode, it is unable to exit it. Pressing the green button either doesn't do anything or causes the machine to reboot.
I've changed SBC, LVPS and LVPS fan (since it isn't spinning - it isn't now either even though I have replaced both LVPS and fan), and also the hard drive.

Bump, since I haven't been able to figure out the problem just yet...

Sounds like loss of +5VDC standby power which is normally cured by replacing the LVPS which you have already done.

I'd order up another LVPS and before replacing it troubleshoot for shorts in +5VDC standby power, something is pulling it down. Could possibly be worth replacing the UI assembly also.

Thanks Richard will try this Monday.

Replaced the LVPS with a known good one and the UI assy as well, but no luck. Will search for shorts in the 5V circuit.

Anything of note pop up in the fault history once you power device back on after this fault occurs?
