I was using my J3 Emerge last night and all of a sudden the screen just went blank. At first, I could press the power button and I would see the Samsung logo for a split second but now it doesn’t do that. You can tell it is trying to turn on because you can see it change from black to a blue like color. I thought it might be the battery so I took it to a store today to buy a new one but he said that wasn’t the problem. It is charging but I just can’t see anything. Do you think I need a new LCD screen or is it something else? Thank you!
