Welcome to Android Central! It could be a problem with the firmware or hardware. If you have an SD card inserted, remove it and see if it boots up. If that doesn't help, see if you can boot into Recovery Mode and wipe the cache: http://forums.androidcentral.com/sa...ing-into-recovery-mode-galaxy-s2-s3-tab2.html
