I have a LG Mobile purchased in Singapore some two years back. Today morning I made two calls and it was working. Again when I want to make another call the display screen has turned into light blue colour and I could not get any screen. I tried to recharge the battery and I am not able to see whether the batter is being charged or not as there is no indication on the screen as the same is blank.
Please hlep me

Take out the battery for a few seconds, put it back in to reset the phone, if that did not help, you will need to replace it or repair it.
