Default MOTO G always shows blank screen even during boot animation

I was watching a video on youtube and then suddenly my Moto G's screen went blank. I can seen a the backlight on the blank screen but nothing comes up on the screen. It can still receive the call which means the android OS is still running fine. It had almost 80% battery when it went blank. I tried pressing power button for 10 seconds for the forced restart. It restarts with a vibration but doesnt even shows the boot animation. I tried pressing VOL down and POWER button combo to bring up the boot menu, but nothing comes on the screen. I am suspecting a faulty screen. Does anyone here have any suggestions?

I have not rooted my phone yet. It runs kitkat 4.4.2.
