My xperia J won't start up

[AyyAshleigh]

All of a sudden my phone just stopped working, when I try and switch it on, nothing happens. I connect it to a power source, it powers up shows  the sony logo, then the charger symbol. After this the screen blacks out and nothing happens, you can't switch it on or anything. the led light just stays green until disconnected from a power source.

Not today no, but what is the need of another pc if I may ask?

It doesn't hurt to try on a different computer

but it is the phone that doesn't do anything, it does the same thing when plugged into any computer or power source.

Sorry to hear that, you will have to take it to a Sony repair center
