Good Morning, mcarlin84. I'm so glad that you have reached out to us today. Sounds like you need our help. I want to make sure that we get your device back up and running. When you say the screen is blank, are you still able to hear notifications coming through on the phone? Have you tried to remove the back cover and pull the battery from the Galaxy S5? Also, has there been any kind of physical or liquid damage to the phone? Please keep us posetd.
