Question [Q] Screen doesn't register input on one section of screen. Repair help?

Hi everyone;

I recently got a refirb F180S and after about a week of use, I've noticed that there is a strip on the screen that doesn't register any input. This is about a 1cm section about 3/4 from the top of the screen, across the whole width of the screen.

My guess this is a hardware issue. Has anyone else encountered this problem? I figure I'll have to buy a new Screen and Digitizer and replace it.

I don't know how much of a problem it will be considering I have an F180S phone. I know that this one has an antenna that extends from the top left corner which would be used for watching TV or something in Korea, Is this going to be a big problem? Would I be able to buy a whole front panel replacement instead of just a screen+digitizer?

Something like this:

I can't seem to find any instructions on how to remove the Screen+Digitizer, so I'm not sure how difficult that would be in comparison to buying a replacement screen+Digitizer+Faceplate.
