Thanks for the disassembly instructions. I was able to fix my power switch by cleaning the contacts with some electrical contact cleaner. After I pulled the two halfs of the case open in step 4 I could spray the switch with some contact cleaner and it worked like a charm.
My original problem was that the power would randomly turn off and had a difficult time turning the unit on. I had to play with the switch toggle it on and off and sometimes it would work. The switch contacts were dirty and all it needed was some cleaning of the contacts.
