I beleive the SMPS IC for the 24dc power supply section is on that board, but let me verify the traces for sure that the VCC is generated fromm that board first, by thw way, how about that 18 Ohms reading on that ZENER, is it really 18 Ohms when you measure across that ZENER?
I have ordered some 1 pin connectors and some 24v 20 watt bulbs to make up some leads for adding load to some of the pins when the 24v circuit is back up and running.
Fixed so far : 1 Home cinema system, 16 LCD Monitors, 4 LCD TV's

It looks like pin #4 (Count from the left) on picture #3 is where the VCC is generated. Do you have a chance to find out what those three ICs are? One of them must be for the PFC circuits.
I'm really struggling to get the model off the 3rd ic though.
I can find those 2 but the one in the middle is more difficult it looks like 103AIW but the alldatasheet data for that number tells me that it cant be that number.
That pin does however connect to either pin 4 or pin 8 of that Ic

I can get this sub board back in and take some measurements now we have pictures of it? looking at these ic's that are on here its dealing with AC is that right?
Probably/possibly I googled lots and couldnt find it -tried substituting some numbers
ie your 1 may have been a 2 after a couple of pints and the W an H N etc and having
accidentally booked several flights on EK726 and EK545 sent the email 5 minutes before
