http://www.fixxboxrepair.info/blog-red-ring-of..., http://fixxboxproblemsguide.com/blog-xbox-360-... so many bundles and console editions available I thought I would try and make sense of it all for you. Though the general hardware failure brought a very bad name to the device and damaging the overall goodwill of the company but it was not the only failure detected. Many other failures listed below were also contributing towards the customer's dissatisfaction.
1. Hardware failure
Hardware failure is the result of malfunctioning of any component on the motherboard and is indicated by a one led flashing around the power button. Usually an error code is also displayed on the bottom of screen referring to the component causing the failure like E74. This is more commonly known as one red light problem. The light that flashes red is Q4. Though it is not critical as the red ring of death error but in 2009 Microsoft had to amend its warranty and covered the one red light problem in it.
This is an indication of the status of the Xbox 360 rather than a failure. When console gets overheated and the temperature of the console gets higher than a predefined level it shuts down the CPU and GPU simultaneously and starts running the fans at full speed to cool it down. In the meanwhile the two red lights start flashing until the temperature gets down sufficiently. Once the device is cooled down it is ready to be run again. To avoid this kind of situation continuous long duration gaming sessions should be divided into fairly smaller sessions and in between the sessions the console must be powered off and plugged out of the socket. It is better to keep it in an airy and well ventilated place.
3. AV cable error
All the four lights flash red when the AV cable is not connected or connected but console cannot detect it. It is a sort of status message than a mere fault so when you will connect back the cable the lights will automatically goes off and console returns back into normal operation.
4. General hardware failure or Red ring of death error
The most notorious one! The red ring of death error is deadly dangerous to turn the console into a brick. When three red lights start flashing it is time to ponder. Although it can be efficiently recovered with care in the home too but needs a bit of expertise. General hardware failure is indicated by flashing of three lights and is termed as a general hardware failure. It could GPU, CPU any other component on motherboard causing the problem. Mainly, the reason behind the red ring of death error is the bad design by Microsoft. Any sort of vibration or over heating results in the movement and expansion of the material and this causes the GPU to leave its place from the motherboard. Thus GPU gets loose on motherboard and red ring of death error appears.
Those of us that own an Xbox 360 console all love and admire the gaming experience it gives us. We especially love the online option that enables us to chat and interact with others who enjoy the same kind of games that we do. However, there are a few issues that come with owning an Xbox console system.
