Hi! Just subscribed to your channel. I've a question. My power brick shows orange indicator. When I turned on the Xbox 360 E, the power button on the Xbox turns solid red after just 1 second. I opened up the Xbox casing and saw the fan actually spinned for a second then stopped. Do you know if this issue could be caused by a faulty power brick? Thanks!
Thank you for the feedback! if you wish to support the channel you can LIKE or SUB or both :P regarding your question: when we get consoles like this issues 90% is the power supply, other 10% could be a components going bad on main board. but based on experience 90% its your power unit. amzn.to/3rDDDou
Thank you for the feedback! if you wish to support the channel you can LIKE or SUB or both :P regarding your question: follow this video and see if the capacitor is bad and if you see anything else blown, also check this old video i have you may have a bad coil: ua-cam.com/video/5tN3kqzsA6U/v-deo.html
🫠Regarding your question, 1st of if you going to replace the varistor i would recommend 1st measure the out put of the wall (home) as depending the city and place the voltage of the homes can be anywhere from 110v- 125v AC, once you know the home voltage then get the correct varistor, because the varistors that they include in the chargers are rated mostly for 140v and that is not good because the charger will burn if a surge happens. so i would recommend to get any varistor from 120-130v . i have opened many power supply and they always use a different model numbers. you can remove the varistor and test your charger and see if it is working. i will open one tomorrow and let you know the model.
Nice video, congrats! But I have another problem. Not a 300uF burnt capacitor. I have a Xbox 360 slim. His power supply is orange. When I press the on button, the red light of the power supply turns on. I have only the +5V at the red wire. When I short the PS ON, I should find +12V at the yellow wire, but not. There is not +12V. I measured and changed the 4 capacitors of 1500 uF near the output side of the board. (they was almost 1350 uF. Apparently, there is no one burnt capacitor. What should I do? What do you recomend?
