Re: iR7105 cannot power on

troubleshooting problem ,
check for AC output from the All Day Power supply at connector J782.
J782 from the All Day Power Supply supplies AC voltage to the DC Power Supply. Check if 5 Volts is present from J784 Pin1 on the All Day Power Supply, to the DC Power Supply--


Disconnect J1718 from the Relay Pcb.
If the display lights, suspect a load from the DC Controller side, as J1718 supplies DC power to the DC Controller.Try powering up the copier with the Fixing / Feeding Assembly out see if the display will light.

Check the wiring from the Fixing / Feeding Assembly, can cause no power problem to be a shorted 5V line the Fixing Feed Assembly--
