Print Page - Southbridge Chip?

It's definately not overheating, so I'm assuming the Southbridge Chip Error is the cause of my 0010 secondary error code now. Anyone have any idea on just how to fix this? Supposedly it's a cold solder issue?

This is easily repaired. I've worked on several with 0010. You need to reflow the SB chip. Basically you need to completely disassemble the 360 and use a heat gun set on a medium setting (anywhere from 500 to 750 degrees) to apply heat to the top of the chip. Don't use continuous heat (hold the gun about a quarter inch above the chip, count to 20 and then remove it for 10 seconds. Repeat this process for 4 minutes). Be aware of other components around the SB chip. Many of them can easily be burned or melted. You may also want to go ahead and reflow the GPU, RAM, and CPU (if the SB chip is failing, then these will need to be reflowed soon anyway). Just put your 360 back together and you're done! If you do decide to reflow the CPU and GPU, you'll need to get some thermal cleaner (I highly recommend Arcticlean) and some new Arctic 5 thermal compound. Make sure you clean the chips until they have a mirror-like shine, and then reflow just like you did with the SB chip. Then use a Qtip to apply a new layer of Thermal Compound to the CPU and GPU (make it very thin, it only takes a drop about the size of a grain of rice to cover the whole chip).

Hope that this info helps! BTW: My heat gun only cost me $19 at Home Depot and I've fixed over 100 RROD consoles with it so far.

Another thing that works great is lighter fluid(like bbq lighter fluid) for taking off the old thermal paste...
Tin foil(Wrapping the board so the capacitors and other plastic parts dont melt) is a great way from saving you trash the board. i have done it to 3 boards even with tinfoil on... so just be careful as you dont want a dead console

Okay, I tried to reflow the southbridge with the instructions given. I did the 20 seconds on, 10 seconds off thing and the top part of the chip separated from the bottom part after about 2 mins. Now I can't get the top chip to reconnect to the bottom chip at all. What do I do now?

uhh I dont think thats a good thing.... youre southbridge is completely off of the motherboard?

I recommend you take some pics before doing anything else

This is exactly why you DO NOT use a heat gun. Stop listening to all the kiddies who watch Youtube Videos...

Heating up the solder balls with a heat gun is a bad move and you will just slowly ruin the solder balls to where a proper Re-Flow will no longer work. Heat gun all you want but the error will eventually return and you will be forced to sell it broken or get a PROPER Re-Flow...

Sounds like you heated it up too much(too much air/heat is a no no) and lifted the chip. =/
