Corona v3 "no power"

I have a console that wouldn't beep or turn on. Power supply light stayed orange. Opened console up and tested standby voltages. Got good 5v but a short on 3.3v. Further inspection showed that u5a1 was shorted, and putting off a lot of heat. Replaced with a 3.3v regulator in a separate location and now the console beeps, but will not power on. I believe that it is due to no 1.2v supply (from same u5a1 fet). Would anyone be able/willing to supply me with any part numbers or even a rating for said mosfet? It would be greatly appreciated!
