First of all hello everyone, I have been following this forum for quite long time and I have learned a lot from all of you people and I am very thankful for that. 
I am writing just because I have no idea what to do next.
So the problem began with CCFL turning off for some reason after a few hours of usage and then started doing this repeatedly. So the picture is still there but no backlight. I opened the monitor and replaced all caps on both VGA and power board. When I tested the monitor again "hours to death" become famous "two seconds to death". I tried my spare CCFLs on these boards and I got the similar problem (some flickering was added to problem, probably because these spare CCFLs were smaller than original ones). After that I tried whole another display with the same two boards. Same result. As a last resort I soldered required cable (power board to VGA board) to another power board I had that works 100%. And the problem is gone. So its not CCFLs, it's not the screen, it's not VGA board it's the power board. I need to fix original one cause the other one can't fit the casing. I replaced the transformer from the working one to the broken one - same result. Replaced the inverter tranformer too - same result. I tested the mosfet - seems okay.
I also take out the big main cap and tested it, it is perfect. (that is why it looks so away from the board)
I have no idea what to check next. Any help here will be much appreciated.
Thank you. ^_^
