I took the old screen apart 9 months ago and now that i work i wanted to change the screen with a brand new one. And now the tablet doesnt turn on anymore

Hi, This could be caused by any number of issues. The one that is most likely, the backlight fuse has been blown. You are able to check for this issue, by shining a light into the screen to see if the images are there and just not visible due to no backlight. If this is the issue, there are any number of repair shops that can handle this repair. Hope this helps.
