mine did that at first... but then i took out the fans, and overheated it... TRUST ME! it will turn to 2 lights.. .i promise.. then put the drive and fans back in and it plays fine (for now)
Great news! My 360 is operational!
OK first thing is kudos to I_Solar_I for the advice on overheating the CPU in order to re-flow the bad solder joints.
To this point I still blame the spring update on causing the 3 ROD on my box. 3 minutes after applying that update the box died! Was working perfectly for almost 2 years.. Anyway that is my own personal opinion.
Below is the list of today's sequence that I performed to finally get the 360 operational again!
1 - Yesterday I had cleaned the CPU and GPU to the point I could see myself in the reflexion of each chip.
2 - Installed a very thin layer of Artic Silver 5 on both Chips. Re-installed both heatsinks using X-Clamp replacement method.
3 - Today based on the help from this forum I decided to tighten the GPU heatsinks to the point where I would get the 3 ROD. Then I loosened them by 1/8" until the unit booted up. The reason I did this was to verify that the heatsink was as tight as possible prior to the box going back to 3 ROD.
4-With the DVD drive still connected I simply moved it off the heatsink and placed it to the left of the box (power and sata connector still connected)
5 - I unplugged the power from the fans
6 - Turn on the Xbox and waited for the green lights to turn to 2 red lights. This simply means the CPU is overheating. Once the 2 red lights where displayed I left the box powered on for an additional 2 minutes.
7 - Unplug the 360 and let it cool down for 30 - 45 min.
8 - Boot up the Xbox and verify that it boots to the dashboard.
9 - Based on what I mentioned about the Spring update i decided to connect the 360 back to the Internet (I don't use live) and see if a new update would be detected.
10 - Downloaded new Update (no clue if this fixed anything!)
11 - With the Internet still connected to the 360 I swapped all 30 of my games one by one into the drive and to my surprise 85% of the games had M$ updates for them. (Game Patches, etc)
I played BIOSOCK for 2 hours tonight and then had to leave, but normally it would only run for 3 minutes. The fans are running properly and the heat that is being expelled by the fans is extremely hot which means it's doing it's job keeping the hot air out of the unit!
