Black screen, no LED light

The screen of my Fairphone 2 has been black for more than 60 hours. The battery was not empty when it happened. I tried to reboot it, switch into reset mode (power and volume up for at least ten seconds) - nothing helped. I also took the battery out, first time only to take it out and straight back in and after I read a few articles in the forum a left it out for half an hour and longer. I also tried to charge it. The led light was not on (not immediately and not after waiting half an hour and longer). I read again in the forum and then tried three different chargers - nothing worked.
I also completed the new update a few days ago.
I would appreciate any tips and help!
