Do not attempt to repair the device yourself if you want to retain your warranty. If you contact Sony they will send you a box and you can ship it to them for repair. If you are outside of your warranty then you can look into replacing your power supply. Usually the power supply will pop and short out if it is full of dust, and a ESD event causes damage. Dust is made up of mostly human skin and human skin has oil which can carry a charge across the circuit board causing a short.
