I accidentally dropped my phone. Now the display is not working . I see all 4 menu items get lighted up when I press the power button. The phone rings. The touch seems to work, as I keep hearing touch sounds and feel it. I tried following steps to debug: 1. Battery In/Out 2. Removing SIM, SD card and putting them back 3. Trying to a hard reset - but no display, so cannot see the reset menu Cannot see files etc when connected to laptop, I think it gets into charging mode. Its 2+ years old and unlocked. I never rooted this. Do I need to replace the screen? Anything that I can try, which I didn't do?
