What is the history of this laptop? How, when, why did the backlight stop working?
IMHO, screens themselves rarely go bad, compared to backlight circuit (cable, connector, fuse, backlight driver, filters, etc.).
You need to troubleshoot that circuit first. Easiest would be to find the number of the board (820-xxxx), google for schematics, find the fuse and test it for continuity and short to ground on both sides, then report back.
If the symptoms before and after replacing the screen are the same (i.e. no backlight) try to return that screen and don't be buying any more parts until you determine the actual cause.

Can you take a good hires picture of the main logic board where the display cable connects so we can see it and the missing fuse location. Paste it into your question so we can see.

I just had the exact same problem, and I paid KT Electronics to repair the motherboard. Problem solved for me. Bump for Dan.

Sorry the picture doesn't show much here. Can you take a fresh one that has less glare and in focus. Also you'll need to zoom in a bit (take a few pics).

Hook it up to an external monitor and see if it generates a picture. Does it tone up (POST)?
