When you say exchange the main controller; Do you mean swap.

Did you check the bootrom, dimms

Did you check all connectors.

Check for pinch connectors.

Cut wire ties.

unplug FAX Board/if installed- re boot- check screen

if you have no rotation & no screen/ u are not able to see progress bar/ - disconnect HDD_turn on power_check if screen pops up w/ E602

For some reason u can not SWAP the iR5570 Control Panels / check your 5v supplies
