Hello, look, they brought me a j7 2016 phone that changed the screen, after that it went 1 day and it was ticked, they recognized him and they put the old screen back on but now it doesn't start anymore, it just vibrates when I turn it on but it never turns on ( or not at least). Any ayua? Thank you.

good morning friend the safest thing is that or they broke the screen when it was placed again because they come out with heat or they didn't connect it well but I lean more towards the first option salu2

One question, if the cell phone vibrates when switching on, should it be only the module? I say not to buy it and then something else
