A long thin electrical screwdriver is the best tool, the base of the yellow power button has a clip with a lip on it, 1) push the screwdriver through the small slit on the flat side of the power button, 2) push down and into the yellow power button , may not work immediately i got it after a couple of goes 3) the power button will lift up slightly itself and just pull it out using your fingers 4) once power button removed u will see one 6 point screw, unscrew and remove switch housing, 5) 2 brown wires 1 blue good idea to label the brown wires 1 and 2 then you won't be confused replacing them back, 6) my DC04 had a broken wire from the main lead simply cut of broken wire and simply replace and fit job, common problam in DC04, Hope this has helped mine is sorted ! peace
