I'm not familiar with the power supply on the Series 2 SA units, but check the capacitors on both power supplies. The tops of them should be flat. If you have any that have bulging tops, you have identified the problem. Another test: Power the system on with the hard drive disconnected from both power and the main board. If you still have the same problem most likely the main board is bad.
There's a difference between needing help, and just being plain ole' lazy.
