This problem indicates that your power supply is faulty it produces dc supply but not enough to transfer other parts. The cause of this is the capacitor or the transistor. If your power supply has a bulge up in the top of the capacitor or not perfectly flat like the others you should replace them because it cannot filter the dc supply and low dc output. Next is the driver transistor if they are leaky it will do the same problem to your power supply. try to test the small transistor beside the regulator. I hope that this may help you regards.

Check the fuse on the y-sustain board. If you they are open replaced it with same current(ampere) ratings and try again if the symptoms still there. Check the voltages at connector (P3). Let me know the reading to asssist you further.
