"Several of those businesses have told Watchdog that the vast majority of consoles they see with the "yellow light of death" can be repaired by heating up specific parts of the circuit board. This process is called solder re-flow. By heating the connections between the components and the circuit board to temperatures in excess of 200 Celsius, the metal solder joints melt, just like they did when the device was first assembled. Console repairers say that this process method is commonly used to repair fractured connections, or dry joints."
But it's not the only rule from Microsoft's playbook on the issue that Sony have been following, whilst they have admitted 12,500 out of 2.5million (a convenient 0.5%) of systems have failed, they refuse to release full figures of failure rates citing them as being commercially sensitive. Unfortunately one rule Sony does not appear to be following Microsoft on is an extended warranty, stating that if it fails after 12 months, it is not their problem. In the UK however at least, the Sale of Goods act would disagree with that statement.
