One thing I forgot to ad...you would probably be best to measure the AC input to the power supply. I don't know the transformer spec, and it may be way out because it is not loaded since the power supply isn't working, but you should see 150+ volts AC or so at the input to the power supply. If you don't have that then your transformer is shorted, or the wires are broken or a board trace is bad or something. But confirm you have some AC input to the power supply before you start replacing parts.... always a good idea:)
