Answer to "Stuck on "Samsung" logo"I had the same problem . Do not do a factory reset swipe and clean of the memory as it will erase everything on the tablet. It did not work for me. Instead shut down the tablet by pressing on the power key on the side. Next pry off the cover from around the edges starting on one side proceeding to all 4 sides to get to the back of the machine. The purpose of this is to disconnect the battery for a few minutes and force a battery reset. Then reconnect the battery cable. You can go on you tube and it will show how to do this. I did it with a dull butter knife and a hard plastic tie used to hold wire bundles together. After doing this, I located the power button with the back case off still and used a ballpoint pen to power up. I got my touch screen back and then most importantly, I DISABLED THE POWER SAVE FEATURE. This feature seems to cause intermittent power problems with the logic board and doing a battery reset solves the problem.
