I'm experiencing very difficult problem with a c253 Machine which is powering on for only 2sec.
i have tried replacing all the boards (Power supply,MFB and printer Control) from the working machine. still the problem exists,
at one time i disconnected all the connector from the print control board then only connected with Power supply and the MFB, but it was still the same.

The boards from this machines are working in the other machine.
I'm Totally confused.
Please Some one Advise in this issue

You mean that your machine is totally OFF? you can check the power supply unit and PWB-A.

It powers on for a 2sec, then goes Off, like the display panel power Light and the light and the Fan on MFB gets on for 2 sec, after after that there will be nothing.
i have tried changing the power supply from the Good working machine, still the same.

I'd have a bad surge protector do this very same thing. Check that.
