Blank Screen-tried various fixes already.

[AC Question]

Hi, I have a 4 week old Samsung Galaxy Tab2, have been getting "touchwiz not responding" messages for the last few days, and my lock screen works fine, but after I put my passcode in, the screen is usually blank (it very occasionally works), apart from the clock/battery % in the top. I have searched this forum for answers, tried turning motion/hand gestures off, tried clearing touchwiz cache in the settings and tried to wipe cache partition in the Android System Recovery. Nothing seems to be working, so if anyone has any other suggestions, I would greatly appreciate it! Thanks.
