Default LCD monitor screen light shuts off!

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.
