@ali1206 sounds like a bad LCD or a loose cable connection. Post some images of what your screen display with your question. If will allow us to see what you see. Use [guide|21499|this guide] for that. Worst case scenario you will have to open it up using [guide|51314|this guide] and check the cable connections to ensure it is properly seated. If so, consider replacing the LCD.
