Searching the internet I see that many people have problems with the Xbox Slim that wont power
From what I see there are 2 large cases
1. Press the button and does nothing
2.Push the button and makes Beep.
1.For what I was reading and trying myself when normally does beep burned u5a1 regulators 3.3v 18/1.2v U5A2 either trinity or crown.
I tested and changed by some that if they worked and the Xbox has caught again.
Two. Case 2 is more strange, regulators seem to be the most well but where I play xbox check my see a problem with the 5V.
For example no power to USB
Another thing I found is that the component U1B1 on xbox that are well gives the following voltage
Pin
1 0v
2 0v
3 5v
4 0v
5,6,7,8 all 5v
you just do not walk and beep
Pin
1 0v
2 0v
3 5v
4 5v
5,6,7,8 all 0v
When the 5V not comes to USB its imposible to read the NAND
anyone know if this may be causing the error?
