kristyhawkins, First thing I would try is a reset. Problem could be that all your data will be erased, except data stored on the microSD card. From the main home screen, tap menu Tap Settings, then Privacy tap Factory data reset Tap Reset phone Enter your password, then tap Yes to confirm Or you can do this for another way of resetting. Turn the power off. Pull the battery out and reinsert it Hold the Volume Down button Press and release the Power button Select Clear Storage by pressing the Volume Down button Press and release the Power button Now confirm your decision: Volume Up for YES and Volume Down for NO If a restore did not make a difference, It is time to open your phone and check for any disconnected or broken connectors. If all of those are okay, the problem will be a broken LCD. The assembly is available at places [http://www.xphoneparts.com/item-search.html?nkw=Samsung%20Epic%204G|like this.] Hope this helps, good luck.
