Are the power rails coming up properly? Measure the voltages at the 3 test points on the power supply board. If not, try rechecking with the output connectors (the single wire and the small 4 pin one with the grey wires) disconnected, to see if the issue is in the power supply, or an excessive load somewhere else in the circuit.
Did you replace the SMD electrolytics, as well? They can fail just like the larger through-hole ones do....
