I have a Galaxy A5 (2017) and it won’t turn on. The screen and lights don’t turn on and it makes no sounds. I tried turning it on and charging it, but it’s still unresponsive. I even disassembled it and put it back together, there was no sign of water damage, broken parts or disconnected wires. I heard about the black screen of death and I thought it might be that my phone might have it, but I already tried force restarting it and it didn’t work. The battery doesn’t seem to be inflated or broken but I still feel like the battery could be the problem. Any help is greatly appreciated.
