Whats difference between LCD backlight and inverter problem?
How can I tell if its LCD or inverter problem in my laptop? External montor works, screen is visible but barely. Thanks 
))
Replace the inverter. If that doesn't work, replace the screen. The only alternative is finding either part to test the other.
