2. tried another display the phone works fine

3. the flex cable is not damaged

4. the connectors are good

now what i need to know what is the cause of the screen going black is it one of the matrix's of the screen glass or something else

quanta portal it is the actual AMOLED screen that has failed. Unlike other screens that may keep a partial display or show lots of lines and streaks, when AMOLED's fail they stay black. "tried another display the phone works fine" clearly identifies that you need to replace the screen to get your phone repaired.

thank you for your answer

but what i'm looking for is to identify the reasons of the fail

like where it happens exactly, what parts of the screen are the cause?

you help appreciated.

I understand but for that you really would have to have a good microscope and test equipment far beyond that of a DIY'er. Most likely failure would be either the substrate that contains the circuitry or the TFT layer, which contains storage capacitors which maintains the line pixel states.

This is my second phone with the same “black screen after lateral impact”. Everything is perfect, since I’m using it on Dex. The other phone was a Sony Z3, the same cause and problem, tested it on MHL, works well. So, the price of a Samsung S8+ screen is like the same of a entirely A21, it’s not worthy replace.
