    Hi,
    Friend
    There are three way to solve your problem-

    1-just dial *#36# then you will get all the hardware listed tap to test or calibrate it.

    2-refresh, then if nothing happens restore to factory settings,if still nothing happens consult your lg technician to look for it for possible hardware problem.

    3-Proximity sensor issue or screen going blank when surfing internet.To fix the proximity sensor error or re-set other sensor.

    Thank you
    all the best/////////////
