사용자에게 답변하기: Why Samsung galaxy tab a 10.1 2016 goes black some timeI've got this same, hear volume up and down but black screen. I'm opened tablet and check the tape for LCD. Tape has two connection. One is on main board , I'm open up the connector, remove tape and put it back. Still black screen. Then I removed battery. Lift gently plastic on both sides of another end of tape, then used bend copper wire to open connector, slide tape out and back in, close connector. Plug battery back on and press power on, and screen back to life.
