Bought and repaired a broken Day One Edition XBox One from Ebay. Ended-up repairing the power supply as it had failed fairly catastrophically.
Detailed the repair in the hope it may help others.
Component / values used in repair:
Switchmode chip: TNY277PN (or better)
R801: 1206 SMD resistor 2.2 Ohms / 2R2
C806: SMD Cap 37 pf
R806: SMD Resistor 0608 '30C' OR 20KOhms
Onboard fuse: T4A - 4 Amp time delay fuse
Elecrolytic capacitor on burned trace: 10 uf/50v
Cracked ceramic cap on 5v standby line: 10 uf / 50v
MOV: 14N471K
X/Y CAP: 0.47uf
Mosfets on 5vsb rail: 2N7002,N, 60V
Adapter Used to convert XBox 360 supply for testing can be found on Amazon for about £6. Use at own risk but I don't see why it wouldn't work. I get nothing from it.
Good luck All...
