Nope, I can't see the Sony/Xperia logo.

Yeah I wondered would a cable be loose. Is it easy to take this phone apart? If not I might try claim the warranty. There is no physical damage at all.
I haven't disassembled the phone myself (I have had no need for it), however I have just watched a YouTube video and it seemed to be easy enough to disassemble and reassemble. If you look it up yourself and judge whether you wish to try yourself or not. If you have warranty from the store you bought your phone at it will more than likely cover accidental drop damage so if you don't wish to risk your phone then that would be your best option in all fairness.

OK I opened it up and I couldn't see what the problem was. Nothing appears damanged, as expected. There are three main ribbon cables, none of them appeared loose. However, when disconnecting the mainboard from the phone case, the middle cable, which lights the LCD screen, has become fully detatched. It seems that unlike the other two cables, it connects via adhesive. I don't have thermal adhesive. When the phone turns on, now there is no backlight in addition to nothing being visible on the screen. PC Companion picks up the phone so all of that seems to be working. But no LCD and now no backlight. Unfortunately, there is evidence of me opening the phone. I doubt the warranty would be accepted now...?

In the reassembly video in document 1277-1354_Rev1 , it shows the three connectors just snapping/ glue situation.

If there is anything else I can do via home repair, what could I do? I can't be that far off, surely?

even if you don't open it, you can't file a warranty on SONY Service Centre if the damage is LCD, just buy a new LCD and replace it

Would that be the case even if I bought it locked on a network? How would they know it's the LCD if I don't say? Once before, with another smartphone, instead of listing everything I understood to the manufacturer, I told them almost nothing and got a full replacement.
