I was having a problem with my battery life so I replaced it with a new battery. After install the screen no longer comes on. So I opened the phone back up and checked the connections and they seem to be connected correctly but still no screen. Any suggestions?
By only replacing the battery such type of fault not appera like that you can change the lcd and check because while the display is band on 45% over while on screwed on board the flex might be damage and cause such type of problem.
