Blank screen..How may i fix it??

Hello,

I use Nokia5130c-2 for almost a year & i am very comfortable in using it.

However, recently..my phone's screen turn white..I cant view anything anymore.
But it still can receive calls(even that i may not know who is calling), unlock keypad(i knew it from it sound), connect wit PC using USB cable & etc..except that i cannot view its screen!

Can anyone help me please...??
