iPhone 6s turns on for a second then goes black?
I recently attempted to fix my friends iphone 6s screen. When he gave it to me it seemed to be working (it was out of power but charge indication popped up) but just had a shattered display. I replaced the finger sensor with his old one, and hooked up everything no problem. After screwing everything back into place, I plugged it into my Mac to charge. I came back after about ten minutes to find the Mac had registered it on iTunes and was asking for permission to access. I hit the homebutton but to no avail the screen didnt turn on. After hitting the sleep/wake button a couple times, the screen came on for less then a second and then went black. I preformed the quick restart (using the homebutton and sleep/wakebutton) and when i hit the power button a couple times it flashed on for a second then off again. I repeated this about ten times and became progressivly more frustrated. I would like to note that the phone only turned on when I hit the sleep/wake button twice, and that the phone does seem to be running in the background. Can anyone help?
Is this a good question?
