Ricoh MPC3504ex won't stay powered on

[Perry]

We had a bad storm last week. Customers router had to be replaced. Ricoh mpc3504ex had a surge protector on it, but now when you turn it on screen says loading, then says shutdown and powers down. I tried hdd, unplugging fax and ethernet . I have a power supply board and controller board on order for it.

If you leave HDD unplugged any thing different? Will it take firmware?

Have you tried a power reset of the SOP? When it shuts back off unplug the power cord from the wall then press and hold the control panel power button until the power led flashes. This will discharge all the capacitors in the SOP which will clear any memory lockup.

i guessing the controller already KO. Had one machine like that, power on untill blue screen, and it just keep restarting itself. After changing the controller, everything working fine

That sounds operation panel main board-y to me.
