Hi, I have replaced the LCD + touch screen, and tested it (when the covers were still off) it worked fine. Then i put back the covers and the touch screen stopped functioning. the pjone gets switched on, volume buttons and power button works, but the touch is not working. i disassembled and assembled it twice but the touch screen is not working. Is there anything that blew up ? may be i connected / disconnected the connectors when battery was still connected and the phone was on.
