回答“My phone works but my screen is blank”I had the same issue with my Note 3. My phone is always in the waterproof case and never drop bad, but one day, the screen went black. I tried to do everything like removed battery, hold the power button for a minute for so many time, but nothing work. I could just only see the green light when I started the phone, the home and the back button when I pressed the home button. I thought my phone LCD went bad, it would be costly to replace. The next day, I just disassembly my phone (https://www.youtube.com/watch?v=XJlsLUNs...) then put it back together. After finished, I tried to turn on again for couple time, and the LCD working again. I just went back and reset my phone and it's still working ok now.
