Hi,

Here is a link to the service manual for your laptop.

I'm wondering, given that I think that you replaced the screen or had something to do with the lid, (you don't say) if the problem might be with the internal display switch, which is located in the lid.

Scroll to p.5 Chapter 2 External component identification, to view its' location and function.

Here’s an image showing the backlight power supply for the screen. This is assuming that the motherboard is a Compal LA-A994P
