XZ Premium flashing screen

[gzyjason]

The screen of my device is not working properly. There is no external cracks or scratches on the screen, but when you turn the screen on, there's flashings and wired white lines across the screen. How can this issue be fixed? the flashing screen

@gzyjasonyou could try performing a software repair (/t5/FAQ/How-to-perform-a-software-repair-with-Xperia-Companion/td-p/1103057/jump-to/first-unread-mes...) and see if it fixes it, but it looks like it's hardware related. in that case your best bet would be to contact your local support (https://support.sonymobile.com/global-en/contactUs/) and send the device to them so that they can take a look at it.
