Control panel error message 57.3 on laserjet 9000n printer

I ahve a laserjet 9000n printer with a 57.3 error message. I have replaced the delivery assembly that includes fan #3,#4 and #6. I then replaced the dc controller board but still have the same error message. Any help would be appreciated.

The number does not correspond to the fan number. 57.3 is a power supply fan error and is I think fan 1. See the attached.
