I need some inputs from people who are very familiar with these
monitors please. I have a 15 inch LCD monitor where the screen goes
dark (blank-nothing) one second after I turn it on. The green power
light on the front as well as sound stay on. What can be causing this,
and how hard is the repair for someone with a strong electronics
background like myself ? Thank you.

I just had exactly that, and it was bad caps in the power supply.

Well if you can shine a light on the LCD and still see an image the
problem may be with the voltage converter for the cold cathode backlight.
I've replaced one on a laptop LCD and it was a small module made by
Hitachi however none of the 5 desktop LCD monitors I own have yet to fail.

I've seen a lot of desktop monitors with bad back light inverters. In
fact, it's the most common problem I see. A lot of monitors shut
themselves off when they detect a back light problem.
