Probably is a bad display. Trying a different screen, possibly the old one if still available, will confirm this hypothesis.

From experience, it is something I've seen a few times with cheap screen assemblies.

Otherwise, the display circuit on the board may have been affected by the drop; or the proximity sensor cable is damaged (try a different one - this is a bit far fetched though).

Tianma is a cheap Chinese brand, and supposedly one of the good among the cheap Chinese brands. However, it is low quality compared to the original quality LCDs that are used for original Apple displays. I also believe that Tianma screen assemblies loose touch function if the display cracks.

where can I buy spare parts?

where can I buy spare parts original ?

I thought the original display not found out by apple. and I thought everybody are manufactured in china and are more good quality tianma

Hey Luca Ciclisti,

I can't say yes with 100% so, I would recommend to open the phone and check the connectors to be sure about it.

My iPhone 5s have experienced the same case, but for my iPhone, i thought it's the storage probelm, as it's a 16GB iPhone.

The black screen problem can be fixed temporary by a restart. i say temporary, because it will happen again, after several days.

I finally fix my iPhone by cleanup all junk files and temporay files and get about 5GB storage back. Now i keep it have about 3GB free stroage space, and it works normally.
