One of my Shark's PSUs went tits-up after a month of use. Replacing the
switching regulator IC (the only IC on the board) solved the problem. Mind
you, I'd already swapped the power MOSFET in case that's what had blown,
so I can't say for sure both were actually faulty.

Both parts are common, and available from Maplin Electronics.

The usual disclaimers apply when fiddling with switch-mode PSUs of course.
Don't hold me responsible if you zap yourself! :-)
