Last gen, did you survive YLOD and/or RROD?

My old power supply simply goes red when I close the pwr enable circuit. I guess it's faulty. The borrowed one worked fine before I got my hands on it and I assume my 360 didn't wreck it. Anyway I don't feel comfortable to short circuit it to find out :)

So it seems it's my 360 that's broken too. Perhaps my faulty power supply overloaded the circuit inside the 360 when it went out. So much for the advantage of an external power supply :/ (Or my 360 shorted and overloaded the power supply) Broken either way.

Alright no problem. Based on your explanation that you can solder and use a meter I figured it might be worth a shot.

You actually wouldn't be shorting out the power supply per se, and the short amount of time you would be making the connection to verify, wouldn't really hurt anything. Keeping the jumpers on for a very long period of time would eventually do damage, but we're talking a long time.

Have you tried looking up the more specfic secondary codes ?

 

Secondary error codes

An Xbox 360 with three flashing red lights will not power on, so the error message must be obtained by an alternate method.

Obtaining secondary error codes

Power the console on so the three red lights are flashing. While holding the sync button on the front of the console, press and release the disc eject button. The lights will begin flashing in a different pattern. The number of flashing lights in this new pattern determines the first digit of the secondary error code, ranging from 0-3, with all four lights flashing indicating a 0. Continue to hold the sync button, and press and release the eject button three more times to obtain the second, third, and fourth digits of the secondary error code in the same method. Pressing the eject button a fifth time should return the flashing lights to the original Red Ring of Death pattern. You have now obtained your 4-digit secondary error code.

Corresponding error codes

To determine which error message corresponds to your secondary error code, use the error code database provided by Xbox-Experts.

My brothers code was (E01) 0001 - short circuit in the console/faulty psu. Some of the codes are very specific so its might help you more than just guessing. It may also help the shop you take it to depending on how familiar they are with 360's.

 

Great info. My 360 gives error code 0003.

The CPU is somehow not getting clean power, can be a cold solder joint under it or one of the external parts like a missing cap etc.

Known fixes:

1) Scan the mainboard and make sure that there is nothing that might short something out, like metal chipping, components, that moved out of place while reflowing, etc. - Especially in the CPU area
2) Replace MOSFETs and regulators that are known to cause it if they were blown
3) Check if the standby voltages are existent, if they are not at a certain area replace the parts in the area which are likely to be defective.
4) Reflow the CPU
5) X-Clamp replacement

That doesn't sound like the quick fix, replacing psu, I was looking for :) Which still needs to be replaced anyway.
