    But did you take voltage readings on the PSU connectors or anywhere else in the machine?

    Have you tested to see if the wall outlet is bad?

    Is the copier power cord bad? Correct power cord?

    Hi all

    just an update on the MPC 307 doorpost.

    Replaced the complete controller and BICU cage this morning, and it started!

    Swopped customer's NVRAMS and HDD over and it still worked!

    So all is well in MPC307 land...

    Thanks all for your ideas and input.

    It will work now, but it might fail in the future because other electronic boards might get broken in the way i described in my earlier post.
