Does anyone have any idea how to fix it? Because it was modded I decided to open it up and fix it. I opened, took off both X-CLAMPS and heat sinks. I cleaned them off as well as the chips with alcohol. Then I put "Antec Formula 5 Silver Thermal Compound" on the chips and some on the back of the heat sink. I bought 8 5mm screws put a metal washer on following by a nylon washer on each screw. I put the screws through the holes and put nylon washers on the other side and metal washer on top. I screwed the heat sinks back on and snugged the screws. I than put the Motherboard back in the case and turn on the xbox, it gets the red ring of death so I left it on for 10-20 minutes. Then I let it cool off for 20 minutes and I turn it on and the green lights go on. So I turn it off take out the board and tighten the screws. Now when I put everything back together it works for about 2 hrs or so and it freezes. What can be the problem?
First clean the heatsink and the chips from thermal compound because you applied way too much...
You have to apply thermal compound of the size of a rice grain and only on the chip dies... The finer the layer the better
Tightening/loosening the screws might help but to give accurate answers you have to tell us your secondary error code for the ROD that you had.

* Turn the xbox 360 on, and wait till the 3 red lights are flashing.
* Press and hold the sync up button (the small white one), while holding that button press the eject button.
* The LEDs will now blink the first number in the code (as described below).
* Release the eject button and press it again.
* The LEDs will now blink the second number of the code.
* Release the eject button and press it again.
* The LEDs will now blink the third number of the code.
* Release the eject button and press it again.
* The LEDs will now blink the forth number of the code.
* Release the eject button and press it again.
* The LEDs will go back to the 3 red flashing lights.
You should be able to determine the difference between the 3 flashing lights and the error code lights by the rate in which they flash.
Here is how you interpret the LEDs to get the code number:
* All four lights flashing - 0
* One light flashing - 1
* Two Lights flashing - 2
* Three lights flashing - 3

it might reset everything there is to reset.
and then if that doesnt work.
throw it away.(somewhat not recommended) buy a wii. xbox360's dont seem worth the trouble anymore.

Can I use a hair dryer for this? It gets pretty damn hot because it can burn my hand. I don't really want to go get a heat gun if its not necessary.
Hairdryers have a safety cut off switch at 140F (60C). The lead free solder melts at 423F (217C).

I don't really want to spend $60 on a heat gun... Do you guys think there are any other ways?
Put it in your oven and heat it up to 220°C
This might fuck up other components though make sure that you isolate the buttons and the capacitors properly...
Search for the oventrick there is a tutorial...
Using a heatgun is better because you can direct the heat at the area which you want to reflow...

Never mind, I got it to turn back on. Too bad its still getting the RROD... I put it in the oven on 340 F for 10 minutes than I put it in for 370F for 10 minutes. I tried it and it didn't work so I put it in the oven at 400 F and left it there for about 10 minutes. It started sizzling so I took it out and let it cool off outside. I just tried getting it to work and it doesn't work. It takes about 30 seconds and I get the 3RROD. Any other ideas?
Secondary error code?
I guess 0022?
However you didnt heat it up enough to reflow the leadfree solder...
It's melting point is 219°C(426°F) you only heated it up to max 204°C(400 °F)
Preheat the oven to 430°F and put it in again for a few minutes, take it out as soon as you see that the components are becoming loose, the solder is getting a golden/yellowish glance or something starts smoking.
And isolate the other components properly, use rock wool if you have got some otherwise use a few layers of tin foil.
I solate everything except the CPU/GPU area(RAM as well), the GPU-ANA-chip and the Southbridge area.
Concentrate especially on the big capacitors as they might blow up.

A few capacitators already blew up. Can you give me a picture on what to cover?
Will do when I am back in the evening, I gotta install gimp again somehow it is fucked up...
I will post the picture when I am done with it...
Post by: Wilhelm_I on May 05, 2008, 12:44:00 PM
Here is the picture...
Isolate everything except the red area to fix 0022/1022(and other GPU only related stuff like 0102 etc.)
Isolate everything except the blue area if you want an overall "reflow" of all components that might cause an error.

Do I also isolate the whole other side? Also, do I take off the heat sinks when I put it in the oven?
WITHOUT THE HEATSINK!!!!
If you reflow it with the heatsink installed it will push the heatsink onto the melted solder balls and flattens them completely.
This wil shorten out great parts of the GPU and the only fix for that is to get off the solder and reball the GPU
It would also be nice if you could post the secondary errorcode for this late ROD.
You should isolate both sides (except the areas marked in red/blue top and bottom)
The top side is more important though

IMHO, baking it in the oven is just about as bad as the towel trick, unless done very very carefully its likely to kill something. a hatgun is always a better method, and can be found cheaper than $60.
what transistor blew? it might be best if you take a scan (using a scanner or just use a camara) of both sides of the motherboard and post them here.
i suspect your original problem was way too much thermal paste, just like someone else said. the thermal paste should be spread very thinly and applied to the die only

I cant edit my post actually...
Sorry about that but my resolution is 1600x1200 so it didnt look that big and making it tinier would have made it harder to see the marked area.
Additonally the host scaled the picture up which is quite retarded as you can now see each pixel.
It would be nice if you could edit my post and replace the IMG-tags with that
