MJE 13001 explodes in a GMT-TR20 USB Charger
This transistor comes from a GMT-TR20 USB phone charger which was distributed with the L7, L9 and other phones. After the explosion a trace to the transistor was destroyed and the PCB was blackened. Wire was run to replace the damaged traces and after the transistor was replaced the charger worked again. Credit: http://gushh.net/blog

Xbox power supply failure damages pcb
This appears to be an Xbox revision 1.1 where the power supply failure caused significant damage to the PCB. The vented capacitor in the picture is a 680uF/16V capacitor which shorted, damaged the FET, and led to the failure of the power plane. Ideally the power supply should sense failure conditions and shut down. The …
