Hello i have 2 power supply a12-220p1a(the external ones for original xbox one) that manifest same fault ; this was tested on 2 xbox one in 2 different location; they work ok but from time to time it can be 5h or in first second at power on when they stop and the led is off; i measured inside and in the DC side the management ic (CP053WD which i can't find anywhere any pdf or data) i think it pulls pin 16 to ground (some protection or something ) ; This open an mosfet that pulls the 5V to ground trough a resistor of high wattage; this resistor become very hot climbing to 100+*C if you don't remove the 220V ; anyone can help me with something? thanks |

If i force manually the source to start and i put load of 5-6A no problem. I don't understand what is wrong but both have same behavior |

Когда неисправность плавающая, то в первую очередь проверьте все электролитические конденсаторы. |
