Apple iMac 21.5 Delta ADP-200DFB Power Supply

[bosscharles]

Anyone ever worked with this supply before? I've got a non working one with no visible burn marks anywhere. Have replaced both startup capacitors with new ones but I'm not getting any power or trickle voltage at all on the imac. Fuse is fine. Can hear it make some noise when plugged into mains.
