I have an xbox that has a reoccurring e74 error. I want to reflow the hana and gpu on it, instead of using a heat gun, could I simply put the barrel of my soldering iron on the top of the chip and let it heat it up that way?
the unit runs pretty cold (compared to others I have) and its an hdmi model and have already removed xclamps. every couple of days the screen fuzzes out and gives the e74 so im suspecting the hana chip.

You could use a hair dryer, but that might not get hot enough before it turns itself off.

I have actually used a desk lamp with a 100 watt light bulb in it and a hair dryer.
Lightbulb on one side and hair dryer on the other...and then swapped them...I've "fixed" 3 boxes like this and once they started working I replaced the xclamp and heatsink with bolts/nylon and metal washers and replaced the thermal paste with artic silver...one is 8 months old and the others are probably 6 months...one used daily..the others used a couple times a week.

Awesome. I was actually going to attempt this soon because a friend gave me his E74 XBOX 360. I am glad to know there is good results.

How could this work? the solder melts at 200+ deg Celsius, it couldn't be possible unless you locked in all the heat at the same time (aka towel trick). I am now doubting if the heat gun trick even works I think its more likely they have created a bend in the motherboard which has forced the contact..
has anyone just used a butane torch directly below the board?

I'm not sure how it works I just know that I tried fixing them without it and with it and with it worked. Again as I have said in one of my previous posts...I have no reason to lie...
Yes I think there are issues with the board bending...there are tutorials that talk about sanding/cutting down part of the case that the board sits on...I'm not an expert...I just know what I've tried and what has worked and what hasn't worked...for me I have tried the towel trick on 2 boxes (not a large amount I realize) and it did not work...which lead me to looking for a heatgun and then realizing that I have no business buying or touching a heatgun...and thus the lightbulb/hair dryer experiments...

Hi yeah sorry, your right if it works it works. Im just interested in what works. I dont like the idea of firing a heat gun for the first time at an xbox mobo either, however I am pretty handy with a soldering iron, I am going to crack open one of mine with a re-occurring e74 error (hdmi model) and heat the pins one by one with the solder iron under the gpu. - Can't do the HANA chip as its a different type of connection. I can do that with the heatsinks attached and keep tweaking the screws to ensure its seated right and doesn't fall of like other people have done.

Ok so my idea of using a soldering iron has gone down the drain, cpu,gpu and ana chip use bga connectors not pins no way im going to try and melt those with the tip of the solder I can see that ending in disater.
Anyways never heard this before: (from llama)
" first step plug the fans in and stick on top of the cpu to keep it cool" then
You want to overheat the unit for at least 30 to 45 minutes. The key is in the lights; as long as it is flashing the 3 red lights (1,3,4) then your are in good shape and the overheating process is working. What you DO NOT WANT is for the unit to actually overheat giving your TWO flashing red lights (1,3) at which point the 360 cuts off power to both the CPU and GPU preventing them from actually getting hot. Again is probably the difference between someone who succeeds and someone who fails."
The method I use, is unplug the fans, turn it on, let it overheat (takes around 10 mins) leave it overheating for 5 minutes, turn off then tighten the heatsinks down again and leave to cool for 30 minutes.
anyone tried cooking the gpu for 30 mins?

whats the diff between your cooking and frying method? do you have the fan on during the cooking? their theory is that the thermal sensor is in the CPU, when it overheats it shuts of the CPU and GPU so when you have two red lights flashing your not actually getting it hot at all, so putting the fan on the cpu allows you to cook the hell out of GPU without it overheating the system.
I have a real stuffed one at a mates I will try maybe 20 mins of cooking with, the rest I don't think I will go more than 5-10 minutes to begin with.
Also a lot of tutorials say after overheating it, flip it up and tighten the heat sink bolts.. thats a no-no that could bump the connectors while they are still melted.

Always fry first. It seals in all the juices and keeps the middle lovely and pink.

I also want to note that I have never attempted to fix a box that was under 3 years old. I buy them already broken off of craigslist...and a couple were still under the 3 year warranty..and when i contact the buyer to see if they want to buy it back...they say they don't have time to mess with it...so I contact Microsoft and get them replaced.
But the ones I have modded/heated up have always been pre-broken and out of warranty.
I think I'm up to 4 or 5 boxes now...
