Hi @EminOd, I am sorry to see this. Please try the following:

• Restart your device.
• Use safe mode to check if any downloaded applications are causing the problem. Downloaded applications can cause your device to behave unexpectedly or affect its performance. In safe mode, your device only starts with software and applications that were already installed when you purchased your device. If the device’s performance improves in safe mode, it’s likely that one or more of your post-purchase downloaded applications are affecting the device negatively.
  You can exit safe mode and restart the device to uninstall the application or applications that you suspect are causing the problem. If the problem is recent and you're not sure which application is causing the problem, you can start by uninstalling the most recently downloaded application.
• Check to see if there is a software update available for your Xperia™ device using Xperia™ Companion. When you update your device, you ensure that the device has optimal performance and the latest enhancements. Tap or click here to read more about how to update and find the latest software version.
• Perform a factory data reset. Note! Always back up all personal data before performing a factory data reset. All data in the internal memory is overwritten during a factory data reset. Content on an external SD card is kept. 
• If there still are lines on the display, contact us.

Thank you for noticing my appeal and responding, but I already did all of the above, and it did not help me. I understand that this is a hardware problem. At the moment I passed the phone for service, I hope to get an act and a new phone ...

P.S. Google Translate

Hi @Sick_Mind,

If you have completed all the steps I listed, then sending it to be looked at for service is the correct next step. Good luck, I hope this gets resolved for you quickly.
