Answer to: iPhone 5 screen won't display and phone is really hot while chargingI'm having the same issue. Approximately 4 weeks after a display replacement, the display suddenly went black while laying on the desk. Initially the backlights were still working, but didn't come back on after a reset. The phone still gets recognised by itunes, however, turns very hot after a few minutes. The heat comes from the mainboard area. A battery replacement did not fix the issue. Reassembling did not fix the issue either. Looking at the only solution posted so far, I suspect it is caused by a shortcut that somehow damages the display but are unable to confirm this theory. I'm afraid that this might happen again after a few weeks if I replace the display, since I don't know what actually caused the display to fail.
