Answer to: iPhone 5 screen won't display and phone is really hot while chargingI have the same problem. The logic board looks ok in my opinion. iTunes does recognize the iPhone but the screen won't turn on, no backlight and also the touch screen is not responding. The metal cover gets hot after 15 seconds. I have replaced screen, battery and dock connector. But still the screen will not turn on. I tried it both mounted in the iphone as bare on a table.
