I have had this tablet since August 2014. It had a charging problem in December and I got it fixed.Now( in March), it wont turn on. i restart it to see if it will work and it loads until it says samsung and it wont turn on. Its charging just fine but it wont turn on. I NEED HELP OR MY GRANDFATHER WILL KILL ME IF ITS BROKEN AGAIN.I do not want to erase the memory because not all the stuff is saved to my sd card. Is there anyway that it can be fixed at home without wiping the memory?
