Hi nasir, My first guess would be that you damaged the touch-screen cable. Try on a new known good screen assembly and see if it works. Be gentle with the cables, don't pull on them when installing the screen assembly. But you can try first to disconnect, clean (using a cotton swab dipped in 90%+ isopropyl alcohol) then reseat the screen cables. If the above 2 suggestions do not solve it, then you may have damaged something during the repair, such as: - ESD damage; - Prying damage, may be visible or not. For the visible part, look specially (but not only) at and around the display connectors on the board. Is something missing, broken, part-removed? Let us know.
