Would a Bad Inverter cause a laptop screen to flicker and look blank? Or am I looking more at a bad back-light? Is there an easy way to tell which is which? I'd hate to buy a new inverter and it turns out to be the back-light.
Background:
I have a Lenovo 3000 n100 that when I first looked at it for a friend that it would light up for a second, off color, (kind of amber) when you first opened the lid, and then it would go "blank."
I disassembled it to make sure the connections were good, and they are. I noticed when I held it just right, if what was displayed was light enough in color (i.e. white) I could see it was present on the screen. It currently will sometimes flicker on for a moment, off color, when you would be expecting it to change screen modes, or on start-up.
It also works fine using an external monitor, other than seeing a post or splash screen. (It's apparently configured for the flash screen, displaying the Lenevo logo.)
