Faian Jamil, if your LCD is cracked I believe that you will definely have to replace it. As for the issues that you had prior to this, it could be a bad inverter a bad backight and/orbad cable. You will have to reasses this when you have a known goodworking screen. The LCD is available here http://www.blisscomputers.net/acer-extensa-4620z-laptop-lcd-screen-14-1-wxga-glossy.aspx and multile other places. Good luck.
