Controller to BICU connection?

Remove and reconnect the Controller.

Remove all units and switch on.

Try loading new firmware. Will the machine boot to an SD card with new firmware?
..........................

[Symptom]
When switched on "Please wait" is displayed, followed by either "Functional problem - restart required" or SC 670. Fuser does not warm up and no drive occurs
....
[Cause]
This may be caused by a failure of the VBCU (Base Engine and Image Control Unit).
......
[Action]
Initially check for the following conditions.

• No LED’s are lit on the VBCU board.
• The LED’s on the controller board are working.
• All 5V, 24V and 12V lines are present at CN200 on the VBCU.
• All 5V, 12V and 24V lines are present from the PSU EXCEPT the 24Vs lines on pins 11, 12, 13 and 14 of CN414.

Should all of these conditions be met, replacing the VBCU board [D014 5133] will resolve the problem.
