ok you open the pcb check the fuse first then replace it if faulty if it burns again then check 4 diodes then see if 200v big capacitor is expanded or not if so then replace it if not then check diodes after transformer if short then replace it

the caps dry out. look for bulging caps. you won't find a schematic for the ps boards. infocus had someone else make them. the problem seems more like a overheating issue. as for the other one with the "just the fans", check the colorwheel.
