Hello. So a good friend of my father, gave him his old J3 2016. He said that it had a problem. So my father gave it to me to take a look, and the phone appeared to be dead. No signs of life whatsoever. But when i plugged it to my charger, the phone make the classic Samsung charging sound! I left it to charge for hours and came back, but it was still dead. My PC recognizes it, and by right clicking on it, i can see that the battery is 100% charged, the firmware version, and the serial number. Kies 3 recognizes it too, but it claims that the phone is locked. The phone is still looking like it’s dead. No matter what i try. (Yes i tried to boot in recovery and download mode, nothing) Any ideas? Update (04/28/2018) I also noticed that when i hold the home and power buttons, i can hear the “screenshot sound”. It’s looking more and more like a dead screen, but shouldnt the touch buttons light up in that case? Shouldn’t the phone vibrate on boot?
@gamwtnsammy from your description it sounds like a bad display. Challenge will be to determine if it is the actual display or if it is an error on the circuit board. That can only be determined once you check it out. I’d start with a new display and while the phone is dismantled check the board for missing or damaged components.
