no power to my console

No power is normally caused by either a bad Mosfet or a bridged connection. In the traditional xbox 360, if you have no power due to a bad Mosfet (power regulator), it will turn on and red ring, reading codes 0001,0002, or 0003. I am not sure how slim error codes work so I couldn't say for sure the source of your problem.. but if you hadn't opened it before I would say check inside of the USB ports and make sure nothing in them is bridged.. also look for bridged connections on the motherboard. Other than that, you'd have to check each mosfet for correct power output and replace the ones that are bad and hopefully that would fix it.

i took a heat gun and heated the back of the mother board for 3min and then turn in on the top side heating it for around 4min and it came back on hope yours work

Jejejeje is very easy i bet u is onley the RF Board the little one behind the faceplate and is onley 15 buks!

Had a problem with my 360 slim. Green power dot no rings. Fan going but what caught my eye was the hdd wasn't spinning up. So I found it wasn't (because of a fall perhaps) seated inside properly. Upon opening and taking it out, I switched it on without it in and bingo. It finally worked. Stuck the drive back in and everything was back to normal. Another cause can be a bent usb inner flange in the socket making contact (same symptoms). Good luck. Hope it helps

Mine is doing exactly the same for 8sec the green dot comes on then goes off again. Xbox charges 500 just to look at it. I have cleaned and replaced the silver paste on the chip and put everything back. Still nothing. Checked the hdd can hear it starts but screen still doing nothing. What can i check?

Xbox360 and the xbox360 Slim will display an orange light on the power supply while the Xbox displays red error lights or display a red light on the power supply (a ground fault) while displaying red error lights on the Xbox. This can occur for many different reasons but I'm only going to reference the USB ground fault issue. Forced entry or twisting of any USB cable plug, whether Xbox controller or other proprietary cable or cable connected device may cause a breakage of the USB connector support bridge inside the Xbox USB port. This bridge holds the USB 5.0 volt metal connector and data metal connector and these metal connectors can get bent if there support bridge is damaged or broken. If the bridge is broken then the next time you plug in your controller or other USB device you may push the (metal) 5volt and data connectors towards the rear of the USB port which is like a small metal box. This will cause the 5volt connector on any Xbox or any device to go to ground and cause any type of red light error and may cause either an Amber or Red light on the power supply while the xbox360 has redrings or the xbox360 slim has a red-light. I am not familiar enough with Xbox One errors at this time to make comments about expected errors, although I'm sure a ground fault would occur if 5v goes to ground. To check for this USB ground possibility, grab a flash light and shine it into each of the Xbox's USB ports located on the front and rear of the console. Check for bent and/or broken pins; if found unplug the Xbox & then take a small screw driver or paper clip and pry them apart and/or off the rear of the USB port. Once completed, power back on the Xbox, Done.!

The light on my power supply is green and fan inside is spinning full blast but yet no power to my two front buttons as well as no beep controller fails to turn it on as well I've checked the USB ports and it has no power
