1 iPhone 5s black screen but iTunes detects
Dear all,
I have a wierd issue with an iPhone 5s. First it showed searching in the top left corner, I figured it out thet this was a baseband problem because of a drop. So I decided to change the logic board. After the change I tried to turn it on but it didn't work with the new logic board. Although iTunes detects the phone and says "There is a problem with this iPhone it needs to be updated or restored" After the restore the same issue happens. I tried another srcreen but still nothing. Than I put back the original logic board and the same issue happened with that, iTunes detects and says it needs to be restored but the screen is black. I tried multiple computers, mutiple charging cables, multiple LCDs and multiple batteries.
Do you have any idea what can be wrong?
The fact that you're getting the same iTunes error with both logic boards would tell me that its one of the peripherals connected, id try disconnecting everything from the logic board apart from the battery and lightning port and try restoring if you get the same problem then use an alternate battery then alternate charge port, process of elimination.

Yes, basically I tried that mathod and the only common things left are the power button and the lightning port. Can any of these cause the problem mantioned above?

I have got a result now, sometimes the screens light up but there are only various colored strips on it

I would of suggested connecting the phone to Wi-Fi and synchronizing the date and time to fix the searching issue..
If it was baseband usually there would be no IMEI / activation issues during setup screen or iTunes restore error 9-29.
