iPhone5 display randomly goes black.
My iPhone5 is out of warranty (2 Years old). My problem is that my display goes black after some usage (on average less than a minute time). I think this is not the normal display problem of black scree. I have already done home+power restart, restore/update to latest software.
History of problem: One day my phones display suddenly went black. I googled and quickly found the home+power button solution. Upon restart my display was on for some time and then again went black. After that since last 15 days my phone display goes black after some random amount of time and then after waiting for some time and pressing power button it again turns for some time and then again goes black. The more I wait the longer my display stays on after turning on. I can receive calls and messages etc when the display is blank. Another piece of information that I think is the major to pinpoint the problem is that, 3 months ago some my phone got some water damage after I was drenched in rain and there were some white spots on the display due to that. The amount of water was very less and My phone was working fine except those annoying small white spots. I want to repair my phone myself as there are not many good service options in my country but I am not sure if it is a display problem or some other chip/cable problem. If anyone has a clue what could be the exact problem that would be a life save for me.
Is this a good question?
