hi y not
i have some tough in my mind~~
i want too ask what you think !!
more i see 360s i get too think too myself YYY YYY YYY
and i see
"Team Modfreakz" discovered that his console with 3 red lights and error code 0102 also had graphical errors and putting great pressure on the memory chips the errors would disappear. This is important because the memory chips, the CPU and the GPU all attach to the mainboard though what's called a Ball Grid Array or BGA. Basically when manufactured there are hundreds of tiny solder balls on the bottom of the chips, the chips are laid into place on the motherboard and then sent into an oven. The oven heats up the solder and in doing so connect the chips permanently to the mainboard. This is used for its low space requirements and ease of manufacturing, the Xbox 1 and many other products use this as well.
What's interesting about Team Modfreakz discovery is that it proves that (his Xbox 360 at least) did not have a good connection between the chip and the mainboard. It's no unheard of for a BGA connection to occasionally go bad or not come out of the oven as it should. If the solder balls were not properly heated in the oven it can easily create a weak or finicky connection between the chip and the mainboard that might be dead out of the oven, or get worse overtime, or even change in reliability based on changes in temperature and humidity etc.
Team Modfreakz decided to use a heat gun and simulate the effects of an oven in an attempt to "reflow" and thus repair any bad solder joints in the BGAs. It would seem that this method was quite successful. Later Team Modfreakz released a video demonstrating the proper procedure for re-heating the mainboard.

While it does not have 100% success it seems to have worked well for many people who were able to get rid of their console problems altogether. The method is quite dangerous and easy to screw up it is certainly NOT for the faint of heart. I would recommend anyone who has problems either return your console to the store to have it replaced or call MS at 1-800-4MY-XBOX to have the console replaced or repaired. I would only recommend attempting Team Modfreakz's method as a very last resort. If you do attempt it, you do so at your own risk.

Hi all
Just wanted to pass this along, I have used the heat gun trick successfully for about 70% of the system I repair, and with the addition of 12v cooling have not had any further issues. You know what annoys me is the last 30%, my conclusion is that the soldering is so bad on these even the heat gun won't work
Now this got my mind thinking, what if we could heat the board up to the 400-450 degree mark and let the solder flow enough to remake these knackered contacts. My solution to this is to put the complete board into the oven!!, set it up for about 400-450 as the thermostats are not great, remember there for cooking food! COVER anything with plastic in it (All connectors etc, remove board from case (obviously) and the heat sinks. Place on a baking tray (to allow you to remove with out picking up board and cook for about 10mins at that temperature. Then you have 2 choices turn off oven and DON'T move the board or move extremely carefully to cool slowly. I have repaired about 2 out of 3 other boards like this. IT MUST BE STRESSED TO BE EXTREMELY CAREFUL TO PROTECT ALL PLASTIC< IT WILL MELT. Successful on 0110 and 0102 errors so far.
Wife not very happy but hey if it works!!
Let me know how it goes
C
How do you cover the plastic connectors? Do you desolder them and take them off the board?
I used the foil backed fiberglass insultation for the plastic parts. The board that have been repaired are still working 4 weeks and counting!!!
then y and y so many error code ?
and i was thinking thinking .................................
went to work and lock onder the mobo i see all and look look look !!!
and i see y !!!!!!!!!!
i need too test befor i post
but to let you know a bet
yes it is macking a shot in bottom of the mobo that is y
and reson for all the error code !!
time to time it will billup a something i dont know how to expland
but i could see the things that macking the 3 red light
if i am right we will see a new malter case from MS soon !
i have some picture but i dont know how to post !! ( i know domass ya it me )
i have 2 way too test if my info is right..
if thingks go well i will post soon !!
hi ok
this is what i think what i have done ?!!
to repair 360s yes i have fex all in my job
now no more 360s (but lots of psp)
i dont know how but it is done!
i give back 2 360s onrepair ...
so i say 87% i have fex not bad at all for newbee! (i think)
all the repair i did i keep photos of motherboard
and MFG date. S# ...
i dont know y but i did (in my job we do keep rco)
i think way the 360 is bill they have saftey divice the keeps
360 sayfuer so frome mobo if it shots up it will lock up
and y it gets shots
what i think time to time betooin the mobo and metel case in the gap it will billup
somekind of tural (you will see this in fire damage computer )
if you look at the bottom of mobo you will see this(look hard)
so with heatgun it is oney a mater of time that it could comback!
i need to be sure it will last a one full year
i am testing 2 360
1 with adding a fiberglass insultation in the mobo gap
2 adding a 12v fan
i will update soon what happans !!
hey tell me what you think ?
P.S. if you could post 3redlight 360s info it helps me a lot
MFG date
