Hi,

I have a iPhone 4s which was initially having issues in iTunes while 'Restoring software'. It was giving ITunes error 21. There was not display when I had received this iPhone to begin with.

I have now managed to do the firmware update successfully.

But the issue is:

1. No display. When I switch it ON, the apple logo appears for like 1 second and then screen is black.

2. I have tried with other screens but same.

Please advise which IC's I need to replace or reflow to get the screen working?

Many Thanks,

Regards,

Yasser.
