@markoo okay so you still have a working tablet just no video. double check all of your work. Make sure that all cables are properly seated and re-connected. If all of that checks out okay then look for and pry damage. see if you accidentally broke a component off etc., If all of that looks good it is a. possible your board got shorted out or b. your LCD has somehow failed at the same time. Let us know what you find out.

I checked everything I saw without going deep into detail (getting every component out) I didn't find any damage or something missing.
