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 …

These pictures come from a Dynapower USA DP-40205 400W power supply. It appears the standby regulation failed and took out the FET pictured above and also the capacitor and resistor near the top of the fan. The exploded piece of the FET was rattling around the power supply when it was opened and the part …

The capacitors in the first picture are failing as can be seen by their bulging. They are supposed to hold the electric charge for the inverter circuit using the 4511GM FET ICs shown above. Once the capacitor cannot hold its designed charge, the BIT3193 PWM controller in the middle of the bottom picture tells the …

This picture comes from a Mitsubishi Diamondview 24″ monitor. An insect came in contact with the CCFL output of this inverter and was charred to a crisp. This lead to arcing on the board which destroyed the PCB and the inverter. Credit: PodeCoet.
