One of my buddies asked me to fix his iphone 6s screen. It was shattered and the phone wouldn’t turn on. I replaced the screen and digitizer and now the phone will make sounds, connect to itunes, but the screen is all black. It will occasionally flash on and i can see the normal home screen for a split second. Any idea what causes this? is it the screen i ordered?
I hate to be the bearer of bad news but I suspect that you have blown the backlight circuit on your logic board. The iPhone 6S has a well known weakness in that regard. Forgetting to disconnect the battery before removing or installing the LCD will blow the backlight filter and sometimes even more. This requires a micro-soldering repair and it is not a DIY repair. By all means, follow Neil’s suggestions (hopefully it is just a connection problem) but if that doesn’t work, then you will need to find a repair shop that does micro-soldering repairs.
Hi jared page Open the phone disconnect battery keep screws separated make sure you replace them in the correct positions. Remove the ribbon cable cover for the LCD again make sure the screws are returned to their respective positions when assembled. Remove all micro connectors and inspect with magnifier both connector and connections clean with tooth brush or similar Reconnect and replace all items test again. Hope this assists Neil
