Xperia XA white lines across screen

[Lawl]

Thanks Rendell my phone on to find it was only black lines, which slowly turned white. The touchscreen worked at first (could feel vibrations at first) but now this is broke too and the screen is completely white. Any diagnostic/trouble shooting?

you might have to repair the phone with XC

but it seems that its a hardware issue rather than software.
