Re: C454e dead, no power
get out your point to point.. find the various fuses in the LVPS & HVPS... test the fuses w/ OHM meter compare.. then do continuity check on harnesses.
did you PULL the PWR boards and check BOTH sides visually?
could the outlets have dips-n-surges on the lines? Voltage on negative lines?
some troubleshooting beyond VISUAL is required on these issues! -
Re: C454e dead, no power
Yes, staring at dead machine won't revive it. Some real troubleshooting steps are needed.
Follow these steps, precisely:
Verify that the MFP is plugged in and the wall outlet is supplying sufficient voltage. With a multi-meter, check the wiring from the wall outlet to SW1 to CN001-1 and 2 on the DC power supply (DCPU). Voltage should be supplied across CN001-1 and 2 on the DCPU.
Verify that MEMB/1 memory DIMM is installed correctly. Clean/reseat DIMM(s). If suspect, replace the DIMM(s) (Memory modules).
Is 5V DC at CN006-5 on the DC power supply (DCPU) and 24V DC at CN007, pins 1 and 3? If not, even if only one voltage is missing, replace the DCPU.
If the previous troubleshooting steps have not resolved the issue, check if LED1 on the Printer control board (PRCB) is blinking and/or ICP17 is OPEN. If LED1 is NOT blinking or the ICP is OPEN, replace the PRCB.
If still a "no power" symptom, replace the MFPB.A tree is known by its fruit, a man by his deeds. A good deed is never lost, he who sows courtesy, reaps friendship, and he who plants kindness gathers love.

O by the way, don't thank me. Just follow up as I can't remember how many threads you started here and not finished them with a problem resolution.

By chance instead the network port flashes? It happened to me that it didn't turn on due to faulty RAMComment

Re: C454e dead, no power
Can you hear the warm-up sound when the main power switch is turned ON?
If no sound is heard at all, the power unit is defective.
If you hear a warm-up sound but the screen is blank, the motherboard is malfunctioning.
If you think the main board is bad, please reseat the memory.Comment

Mfp board took a dump. Tried another and it came right on so off to Hytec with this one!Comment
