Hi again @Dark-Orchid and thank you so much for the pictures!
I have to agree with @GANGSTAR here, it does look like a defect screen, however just to make sure that it's not related to the software in the device, I would recommend that you perform a software repair using Xperia Companion, as this will reinstall the latest available software in the device.
Do note that in the same process, all data stored on the internal storage will be deleted, so it's important that create a backup using the same program, before you start with the repair.
If the line is already showing in the start-up guide after the software repair has been finished and you have powered on the device, get in touch with your Local support team and they will assist you further with having the device sent in to an authorized service centre.
Feel free to keep us posted on how it went!

Thank you for your response. The problem has been resolved and I have no idea how or why! I'd switched off the phone and restarted it, messed about with display settings, switched it off for the night and restarted in the morning and it was exactly the same. Then I glanced at my phone at around midday three days ago and the line had gone. I've switched my phone on and off etc. to see if the line had returned and left it a couple of days just in case and, so far, it's not reappeared - it's bizarre. I'd like to thank you for looking at the problem for me. The forum has been really useful as it has answered my queries about what it could be, possible solutions and the fact that my phone supplier is blatantly wrong in saying that it's out of warranty. So many thanks for your help and advice. It's much appreciated.

Thank you, Jonas. As I've mentioned in reply to @Gangstar, the problem has disappeared (hopefully). Thank you for your advice especially the software repair option which I had never heard off. Advice like that is gold dust for amateurs such as I. I did make me think whether an update had caused or solved the problem but my tech knowledge of phones is as poor as my photography skills! Again thank you for your help, it is really appreciated

Hi again @Dark-Orchid and that is awesome news!
I do really wish that I could tell you exactly what fixed it, but as far as I know the only setting in the device that can produce such a line can be found in the Developer options.
Hopefully the line won't show up again and if it does and it does not help to turn it off and mess around a bit with the settings, you have all the needed troubleshooting in this thread.
To be honest with you, neither retailer or the manufacturer should never say that the device is out of warranty (if it's still in the 2 year warranty period) before the device has been examined at an authorized service centre, as it's the technician that examines the device that makes this decision, based on the warranty terms and so forth. I do understand that it's frustrating when you seek help and they reply with "this is not covered by the warranty", when they don't really have the support for the device.
Feel free to let me know if there is anything else I can assist you with and thanks a lot of the kind words about our forum, that makes me really happy and have an awesome weekend!
