[Electrical] C250i Won't Power On

[copytechtrouble]

Hello all,
I have a Develop C250i that wont power on. when the power switch is flicked to the On position, I can hear an initial sound from the power supply but nothing else happens, no lights or sound, completely dead.
I've tried a new power supply, base board and power switch from a known good machine but the issue is still the same, machine dead.
the customer said it was working perfectly all morning but when they when to print after lunch, the machine was off and wouldn't turn back on. no power surge or other power problems occurred on the site.
anyone have any ideas?
thanks

Sounds silly but i would check that the correct power is coming from the plugin. Is it plugged into a EPS surge protector? if so just try it without it. I have seen those go bad before.

Does display lights up? Stuck on boot with 25% indicator,? You may try SSDB(NVME SSD). Those were known to fail. There is boot problem troubleshooting based on led lights also available on these.

that reaction from the machine is usually a short or a blown up board. if equipped with a 704, try removing the ds board, try with side door open. also if it was running fw 45 or earlier the ssd is toast.

Re: C250i Won't Power On

try with all the doors open, if the fuser is shorting out it can do the same symptom but keeping the door open will NOT supply power to the fuser.

Had something similar a few months back. Machine would boot up until the scanner lamp powered up, then would immediately short out and go dark.

Try powering it up with all doors open, this will stop everything but the boards from getting power. If it still does it, then its likely a board issue, if it doesn't then it might be another component shorting out. But they made some changes with the i series, now all boards have 5v and 24v regardless of the main switch so to get it to reset itself you may have to unplug.

Had same issue recently, was the CPU board.

Re: C250i Won't Power On

I have had a similar problem with 3 of these machines. It was the CPU boards on all 3 machines, 1 of which had to be replaced. If you pull out the CPU board and reseat it, It may solve your problem. Make sure you slide the board in at a 45 degree angle. One tech didn't slide it in at the correct angle and the machine was dead until he went back on himself to see what he might of done.

I am currently having the same problem on the same machine type. Have replaced, DCPU, BASEB, CPUB and the power switch. Through all of this there is 5 volts at the DCPU and at the base b but the machine will not power up. We have jumpered the wiring harness on the switch to bypass it all together without success. Continuity has been confirmed in the wiring harnesses and have not been able to detect any shorts either. Anyone have any ideas? I'll sacrifice a chicken and a mother board at this point. I'm out of ideas.

When you re installed the CPUB did you make sure you did this at a 45 degree angle? We had a tech fit a CPUB straight up and that machine never powered on until he back tracked what he had done.

Yes

I had this recently and it was the actual power switch. Never saw that before. Had tried psu/cpu/memory etc first.
