After removing the screws, dis-assembly is nice and easy, the top part of the power supply (label side in my case) will hinge up and out of the way.
The hinge for the cover simply slides out revealing the power supply in all its glory
As with every power supply repair that can be found.. Anywhere, the output filtering caps are first to fail.
These caps are rated at 1000uF @ 16V, and there are three of them crammed in down there. All three of these are used to filter the output 12V rail from the power supply, one filters the output rail before the current shunt and then the other two filter the final output voltage.
To remove the main circuit board from the unit is quite easy, just unplugging two cables and then removing 4 screws total from the unit.
And now comes the easy part, just desolder and replace the caps.
