You need to visit the nearest Apple Store as it may possible that your display is damaged.

Re: white line appearing on LCD

I have tried replacing the lcd/digitizer assembly twice on iphone 5c. Both screens initially look great and then after assembly the lcd starts to display white vertical lines and digitizer fails to respond. I now have gone through 2 LCD $160. My supplier says it is static electricity. My question is there a resolution?

I'm having the same problem. Checked the connectors with a microscope. Tested with 2 screens. The connectors are looking brand new, when fitting, there's a nice click but no response at all from the digitizer and the squares and lines on the screen.

I'm also reading about electrostatic problems, but i'm working here in the shop with a anti electrostatic mat, and bracelet (or hows that called in English)
