Chosen Solution

I recently replaced the LCD on my Z3 play, and it was working great for about a month. Now I have a vertical line in the center of the screen. The line goes away if you slightly press down on the bottom right corner, or if you slightly lift the LCD. Any ideas what is causing this and how to permanently fix?

There are two possibilities:

  1. The screen is warped, (Manufacture defect) Would explain why when you press down on parts of it the lines go away. Your re-aligning the internals to make a solid connection.
  2. Faulty Digitizer, (Manufacture defect) Same as the first reason, but it is generally caused by the hardware IO’s chip giving a crappy signal. Firm bet is on number 1 though. Call the manufacture and see if they still have it under warranty, if it is not, you can replace the screen cheap.
