Hi @Peaches4178, I'm sorry to hear about that. 

First of all, can you test the display in the Xperia tests section in the support application, you do this by going to: Settings > Support > Xperia Tests in the bottom right > Display. Do you see the lines here? 

You can also try putting you phone in to safe mode, you can read more about how you boot your phone in safe mode and what it does here.

Let me know how it went!

Hi yes I've tried that still got the yellow lines

Okay, if you have tried that i would recommend you to contact your local support team for more information about how to send your phone in to an authorized service center and get it examined. 

If you have any further questions, please let me know.
