I have this exact same... Did you get a solution?? What can be done to fix this?? Tab A screen powers down or goes black when I move it, and sometimes will power back up when I move it again. I don't hit any buttons, it does it in safe mode, it did it before I added any apps, it does it now that it has apps, I ran diagnostics and nothing was found, all parts function like they're supposed to. There is absolutely nothing I can find to explain this. I went though the programs myself, I didn't see anything there that could explain this. I thought it might be auto rotate for the screen so I turned that off, still does it if I move it too close to me or lay it down on the screen or faced up.
