Hey Guys
I got myself a Xbox 360 Slim Trinity today.
It boots correctly, goes to the dashboard but it has a DVD drive which is not functioning correctly (Open Tray problem), so i shut it down to go and look for the problem.
The guy i got the xbox from told me that he had a Xkey installed, but not anymore.
So the first thing i thought of was the SATA cable which can get faulty after some fiddling.
After replacing the SATA cable i tried to fire it up again but didn't boot anymore.
When i press the power/eject button you hear the PING, green light for a second, and nothing.
No spinning fans, no sound, PSU not powering on.
So when i opened the xbox up again and took the DVD drive out i found a horror story around the HANA chip. It looks like a cap exploded and like someone pulled some things out with force.
As you can see on the picture below:
Bigger picture
Resistor R3B15 was missing, a wire was soldered and was going to the underside of the board, the Trace left of R3B15 is completely gone and all caps/pads around are black (and a bit fluffy). Looks like a RGH was used, burned out and has been removed. The cable from R3B15 to the bottom was going to this trace and was loose:

In the middle of the picture, just right of the hole and left of the (foxconn) text is a visible trace of copper. I've found out that this trace is in connection with the trace to R3B15. So they apparently tried to bridge it.
I've resoldered a 33Ohm resistor at R3B15 and i've repared the bridge but still no boot.
When i connect everything and try to turn it on i just get the beep, a green light for a short second and nothing more. The PSU light is amber and does not switch on.
I find it so very odd that the xbox booted before (with problems that is) and after just (carefully) replacing the SATA cable nothing works anymore.
Do you guys have any clue what to check next?
Is the bridge not good? (STBY_CLK right?)
Or are there other things to check?
I have an oscilloscope available, so i can check the signals on the trace going to/from R3B15 if needed.
