Benq E2220hd Monitor Start Up Problem

Start up with no computer input shows "BenQ Logo" (2secs) then black... then "No signal HDMI 1 cable connected" for (2secs) then black... power button stays on... just blackness. Read about power transistor resolding on inverter board. I have taken the monitor apart to the boards. Don't know which of the 3 is the inverter board. But when I do should I just resolder and check first before I check the transistors for faults and replacing transitors? also all caps look not blown out. here is a video of issue http://www.youtube.com/watch?v=QzT58tOmf-8&feature=youtu.beand here are some pics of the inverter boardhttp://s91.photobucket.com/albums/k288/angelboix/E2220HD%20BenQ%20lcd%20monitor/I do not know where the power transitors are... so if anyone could help me out that would be much appreciated!
