Sharp MX-M850 error code A0-01

[Froota]

Hi guys,

We have an issue on a Sharp MX-M850, as we are getting fault A0-01. (PCU ROM abnormality)
This problem is mostly generated at morning when the machine has to come out of the standby mode.
After rebooting the problem is cleared until a few hours later, where we have to repeat the same procedure.

We already rewrote the firmware, replaced the PCU PWB, memory, MFPC PWB, W-ICU and main power PWB, but without any result.

Someone with a solution?

Regards,

Froota
