What to do if the phone doesn't turn on
I have replaced the broken screen and everything was fine.
Then about 3 days later, when I pressed sleep/wake button, the screen showed apple logo then black screen.
So I pressed sleep/wake button then again, the screen showed apple logo then black screen.
After that, no respond after pressing sleep/wake button.
Plugged into wall socket, came back to life.
Then following day, same thing happened but this time no respond when I plugged into wall socket.
So I connected to itunes but nothing.
When I did sleep/wake 2-3 seconds then add home button for 8 seconds then release sleep/wake button, the itunes recognised the phone and took it to recovery mode.
I have attempted for recovery mode twice but error 4005 came so couldn't recover.
I opened the phone and disconnected battery connector then connected then started.
This time apple logo and ten swipe screen for 2 seconds then black.
Then pressed sleep/wake button then came apple logo then black for 4 times and nothing.
Can anyone suggest what is wrong with this phone?
Oh, I tried to connect to previous broken screen and it doesn't turn on so I guess it's not screen.
Is this a good question?
