Solution for white display / no display / lines on display plug and unplug lcd display connector and check. check with any other working lcd screen in order to verify whether iphone 5 lcd display is faulty or if there is hardware problem.. It’s natural to feel frustrated when your iphone touch screen is not working. you use your iphone for everything, from making calls to scrolling through pictures — but don’t let your “touch screen troubles” get you down.. Even though the iphone is a device that is extremely convenient to have, it still can cause frustrations. specifically, there may be times when the touch screen does not work properly..
I have used the iphone 4 (factory unlocked) for more than a year now with only minor issues. like on a usual day i was playing a word game "rumble" then quit the game, connected my earphones for music & pressed the "home" button on the phone to unlock it and the screen was black.. My iphone 5 screen had gone blank all of a sudden and was working just fine calls, siri etc. i just pressed the home and power button together for 10 seconds and the phone got rebooted and the problem was resolved.. If your iphone display stopped working after you dropped it, your screen is probably black because the lcd cable (display data connector) has become dislodged from the logic board. if your iphone display stopped working after it got wet, your screen is probably black because the lcd is broken and needs to be replaced..
