Canon IR C2880 No boot, Blank Screen from Power on.

[danman]

Hey all, Here's an interesting one.

Changed a Default Gateway Address on this IRC2880 help the on/off button down and "shutdown" the machine to make the settings change take place. Flipped the Power switch on the right hand side and left the machine off for a minute. when i turned the power switch back on, the "power" light is green and the machine is going through the checks but the screen does not cahnce from being blank (no progress bar or logo) machine sits there after it checks and doesn't make a noise.

did the usual Unplug the power cord from the wall and let sit routine. plugged it back in still the same.

Any thoughts are greatly appreciated.

Thanks!

check fuse on power supply, if blown replace the power supply pcb

[danman]

Where is the access panel to check the fuse? haven't working on this machine very much.

Thanks for the quick response!

you need to remove the rear cover of the machine to access the power supply pcb, also check the boot rom is seated correctly(you need to remove hdd to see the boot rom) remove it and clean contacts then reseat it. hope this helps

Check the remote signal at J254E, pin 3 on the Controller Power Supply (UN12).
POWER.JPG

The remote signal should be at least 3VDC.
Also check the signal back to the Low Voltage Power Supply at J302E, pin 3 and see if it is also low.

The Low Voltage Power Supply may be defective, thereby preventing the Boot-Up Process to initialize. The part number for the Low Voltage Power Supply is (FM2-5544-010).

Title : The machine has a green LED on with no cycling. Error :
The machine has a green LED on with no cycling. The machine was first found with the AC driver fuse blown. After replacing the fuse, the machine still did not have a display or any cycling, just a green LED on the control panel.

CHECK....
that the remote signal (3VDC) was making it to the AC Driver PCB at J209 pin 3, it was then determined that this signal should allow AC to be supplied to the Low Voltage Power Supply PCB at J301. Once the AC is present on connector J301, there should be 13VDC out of connector J303 pin 9. (orange wire) on the Low Voltage Power Supply PCB. If 13VDC is not present on pin 9, it would be necessary to check pin 9 with connector J303 disconnected. Turn the power off, then disconnect J303. Go to pin 9, when the power is turned on, there should be 4VDC at the pin for about 2 seconds. If this is not seen, replace the Low Voltage Power Supply PCB. In this case, the replacement of the Main Power Supply was needed.The Low Voltage Power Supply PCB cannot be replaced by itself, it must be replaced by ordering the Main Power Supply PCB, which comes with the AC Driver PCB and the Low Voltage Power Supply PCB. The part number for the Main Power Supply is FM2-5544-010. Check the image below for reference.

Had to replace a low voltage PSU recently for non booting.

Check the boot rom and the ram's on the ip board

Low Voltage PSU might be a Winner! only Measured 1v, ordered replacement. Thanks guys!

[danman]

ordered a Low Voltage PSU and a bootrom, replaced the Low Voltage PSU still nothing, replaced the bootrom and solved the problem.

looks like it was a combination of both. although the main control board had the necessary LED lights on with the old Low Voltage PSU. so not quite sure if the bootrom was the only problem or not. decided not to chance it.

Thanks Again!
