Hi, my phone went blank all of a sudden. Everything inside is still okay, all functioning well, no cracks but just blank. Model samsung galaxy note 3.

1) How much to repair the blank problem?
2) How long will it take to repair it?
3) How much do you sell the samsung pen touch screen as mine already lost.
4) How much is the glass screen protector?

Please reply here or PM me asap. TQ.
