Console not turning on?
I've tried replacing power bricks and trying in different wall sockets and the standby light is on when it's plugged in but when I press the "On" or "Eject" button it doesn't do anything at all?
The slim edition of the classic Xbox 360 with a 250GB HDD and built-in Wi-Fi. Repair requires intricate prying and special tools.
Try replacing the rf board there cheap that should fix your problem. If you hit the eject button or power button and it don't do anything. Now if it powers on for a second with a green light then powers back off you need to reflow or reball the south bridged and your system should come back to life.
