sounds like a jacked up usb port is shorting out.  shine a light in them and fix the one that doesn't look like the rest of them.

I have already seen it and normally I do not have bad contact or a course circuit in the USB

Hi,
everyone will throw at you the "check for shorts" statement, you might not find them... well i didn't.
I have the same problem as you and no solution, somewhere (on standby) one of the 3.3V rails is shorted.

This is the thread with my problem and with no help:

And this is something you definitely must look at:
http://xbox-experts....-xbox-360-slim/

First, with the console on 'stand by' check the 'Realiability Header' this is a good start to check for shorts.

Report that.

you did not try to change the MOSFET normally has its

No... i didn't

i check both voltages and they look fine, just like in the picture: http://imageshack.us...regulators.jpg/

But in fact i did bought 4 of them to have them replaced, but it's on hold ATM.

Are you talking about the MOSFET  ones in the picture or any other else?

Normally it can help you and help me as I have yet to test his or changed

[chapas5400]

I'm (almost) sure that i have tested both of those MOSFET pointed by the thread you referenced on a good trinity board on standby and each one of them yield 0 Volts in any pin. I did not unsoldered them, my mistake, i'll have to try that.

then you will replace the two you vien me shown in the photo?

Otherwise me tonight I'll test it and test the other and I'll tell my part what gives his OK

[chapas5400]

Yes, i will replace them, if the test on them fails; still i'll have to buy them first i don't have any spares at home.

ok informs me news I hope it will work if you also have a beep only with your slim!

how is it fail?

[chapas5400]

I really don't know how to explain how it failed.
It had a Matrix 1 glitcher installed.
I had played before many hours on it, this was one more session, didn't move the console anywhere.
Connected one controller at front and the hard drive on the back (rightmost USB port), played for 30 min. a xbox live game, turned off the console, did notice that the fan spin a lot faster than usual on turning off the console. Few days later tried to start it and never started up again. Only makes one beep and nothing more.

Strange right... this is the second one.

Hello friend,

So your new quesque done?? you changed the components?

[chapas5400]

Hi there,
as I told you, don't even have the components to replace, today i took the reference from them, and I'm going to place the order. I will only be able to test with new components in 3 or 4 weeks.

[nagui84]

Hi, here is the good and I found no voltage (or black arrow)

I do not know what I should have changed the 3.3v

help me please
