I disconnected my LCD screen when battery was still in. No backlight.

I disconnected my LCD screen on accident without removing the battery. I smelt a burnt fuse smell. When I use my new LCD screen there is no backlight. I checked the fuse with the small dot on it, and it looks intact. Do I need to replace the fuse regardless? Do I need board repair? Any help would be appreciated.

Thank you for your time!

You'll need to test continuity of the fuse a visual inspection is often not enough.

But lets see if the backlight fuse is blown by using a flashlight shining through the Apple Logo. Are you able to see the desktop icons?

Well, you're lucky! The backlight logic is damaged. Hopefully its just the fuse link.

At this point I think you'll need to visit someone who has the needed parts and micro soldering skills.
