This is normal after 6 power failures in 3 hours!!!
Replace the capacitor, but have in mind that you might more components, malfunctioning there. If all go well and you repair it, install a power stabilizer between your xbox and the power socket. Just to be safe for the future.
Haha, yeah, something in the kitchen was repeatedly tripping the breakers when it was being used (suspecting a faulty kettle!).
I have no soldering skill at all, so replacing the capacitor is going to be a problem, but I'm gonna give it a go anyway, really nothing to lose at this point.
