Having problems with your Dell UltraSharp 1800FP 18.1" LCD Flat Panel Monitor ?

I have a Dell 1800FP monitor. I get no power lights at all

\015 I have opened the unit up for a quick inspection of the power supply and here is what I found.I have checked the AC through the full wave bridge - it is good.I have 165 Vdc all the way until Q902 ( which I am assuming is a SCR??Could the problem be in IC 901??Does this power supply need to be loaded to get the 5 and 12vdc outputs??I have hooked it up on a bench with no loading.Any help or schematics of this thing would be appreciatedThanks Rob \015
