Yup, I would suspect the capacitors on the power board.
Zaccaria – Power Board (all components from BigDaddy)
C1 = 150uf 350v axial
C6 x 2 = 10,000uf 16v radial
C9 = 1uf 16v radial
C12 = 1,000uf 25v axial

Here are a couple other suspect parts that are common to fail on a power board (more for the displays). Check with DMM
High power:
R1 – 100K ohm 1w (Brown, Black Yellow)
R6 = 47 ohm 5w (coming from eBay) Yellow, purple, black, red

If you need bridges, just get 25amp 200volt or higher

Here are the test point voltages

Gen2 Power Supply Test Points.
Test Point Location Voltage
TP1 170 vdc
TP2 12 vdc
TP3 5.6 vdc
TP4 5 vdc
TP5 39 vdc
TP6 -5 vdc
TP7 (power fail) 5.6 vdc
TP8 Ground
