You can try to do soft reset (Just press and hold both the Sleep/Wake and Home buttons simultaneously for at least 10 seconds, until you see the Apple logo. You can let go of both buttons after the Apple logo appears) If it doesn't work You can try to reset settings it will not erase any of your data but will erase some of your settings So its good to back it up before you do reset. ( Goto Settings --> General --> Reset --> Reset All Settings) and the last option is restore your iPhone I hope it helps .
Hi. If you already haven't done this please try . Do you know how to get into the recovery mode ? (Turn off the mac then Press the power button to turn on the mac , right after hold the left option key and wait until you see the recovery HD then chose the recovery HD and hit enter ) When you are in recovery mode you will see disk utility click on it. On the right pane of the disk utility you will see Macintosh HD unless if you haven't change the name of your HDD before, Highlight it then go to first verify disk then repair disk . Let me know how it goes . Thanks
With help of luck you have blown the backlight fuse. To be able tell you need a multimeter to test the fuse if its good or bad To be able to fix you will need a Soldering station and skill. If the fuse is good then things gets more complicated but if the fuse is bad needs to be remove and replace with good one then see if it will fix the problem. google (a1278 backlight fuse )and see how Louis does . I hope it helps . Thanks .
Hi arneblommaert3 Dc board is a part of complex circuit talks to each others and tells the charger to turn on and charge the mac. So if there is no light on the charger it means there is a problem in that circuit includes the dc board .Maybe its the dc board itself or one of the other component on the logic board .I would recommend to start inspecting from where to water contact has occurred . Thanks .
