The problem is, the console has no power. Doesn't respond to power button, eject button, stays off. PSU led is always orange. Here are the things i found: 1.8V standby is okay, 3.3V is okay too, at the power plug from pin 1-3 there is 0V, from pin4-7 there's 0.2V, that grows to 0.3V if plugged in, SMC_RESET_N at J2B1 PIN 6 is always low, no matter what, its at 0V. I tried to power it with my lab psu so i could find whether there's a short (thats potentially feeding back to the power connectors) but nothing. Still no life. The 3.3V is there at the RF Board so that's not the problem, the RF board also work on another motherboard. Already tried to reflow the NAND, Southbridge, and ANA to no success yet. Any ideas what could cause this? I'd appreciate any help! Thanks for reading!

EDIT: Forgot to mention, that i measured connectivity between J2B1 Pin 6, and all the points that are mentioned being connected to SMC_RESET_N, and all seems fine.

The console is LTU (i think). Is jasper. pure. without RGH or JTAG.
Well. after the flash, we tried to turn it on. but nothing happened. the controller wont receive power. the brick stays orange.
i know the led on the brick changes according to consumption. without anything connected, the led is slightly weaker. with the XBOX connected, it gets a bit brighter. this is normal response. with the xbox broken or not. but, she stays orange. without trying to get on.

i could try to force her on. but i doubt that this would be a good idea. and probably some magic smoke you come off him.

Either i think maybe a small ball of Solder joint got off and its shorting somewhere else.
We shaken it a bit to see if anything would come out. bur nothing really came out.

I recently picked up a broken xbox 360 for $5. I wasn't expecting much, but it was actually working when I got it! It would overheat the eDRAM, in about 10 minutes. Replaced the paste, and it didn't help. I checked the V_GPUCORE Power rail, and it's fine. But after about 3 weeks of sitting, it now will turn on and flash 3 red lights. Using sync and eject, it has error 0031. Reading online, the common issue is a bad power regulator. They have information on xenon library, but it's very vague on where to check this stuff. So, does anyone know, where i can check if V_5P0 or V_MEM are shorted? And, is there a refrence image i could use to try and find a bad regulator (if thats the issue), and one that has a map of the power rails? Thanks for any help :)

I bought the new laser, changed it, and it still gives the same error, any idea what it could be?

A Falcon V2 (Mfd: Sept 2008) flashed to L.T. 3.0 - This one got the ring of death

A Jasper V2 (Mfd: Sept 2009) This one still works

What should I do to make the Xbox recognize my profile?

My xbox 360 wireless controller shows that it’s connected at number 2 but actually it’s not connected and there are no other controllers. How can I fix it?
