Clean the PCB pad area
2 minClean the desoldered board area using isopropyl alcohol and a lint-free swab to remove residual flux and debris.
- 13
Solder replacement components
5 minInsert the new capacitor or fuse into the board, paying close attention to polarity, and solder the leads securely in place.
- 14
Clean the cooling fan
3 minHold the fan blades still and use compressed air to blow out dust accumulated inside the fan shroud and heatsinks.
- 15
Reinstall the metal shield
3 minFold the top metal EMI shield back over the board and secure it with the Phillips screws.
- 16
Reassemble the plastic housing
3 minPlace the internal assembly back into the lower shell and press the top plastic casing down until it snaps closed.
- 17
Secure the outer screws
2 minReinsert and tighten the four Torx T10 screws into the bottom of the power supply casing.
- 18
Reattach the rubber feet
1 minPress the four rubber feet firmly back into their recesses over the screw holes.
After your Microsoft Xbox 360 power supply repair
Power the Xbox 360 back on and test the power supply repair function before you put every screw away. Check touch/display response, charging, cameras, buttons, and wireless as relevant to this repair.
