Blinking LED when charging using Dock

[Delaitre]

When I plug my phone on the dock to charge it, the led is blinking and the phone is not charging.
The charging indicator appears near the battery symbol then goes away, appears again, disappears again,..

Is the dock faulty or is it my phone?

Quite sure the phone is faulty cause same problem with another dock...

Any idea to solve this problem?

Thankd

Is the dock connected to a mains socket or a Pc's USB port?

Thanks to try to help me.

Both chargers I have tried are connected to wall, not PC. And also the charger in my car is not working. 😞

If the dock is fine and the mains socket is fine then I'm sorry to say but you would need to either return your device to the place of purchase or contact Xperia care and ask that your device be inspected http://www.sonymobile.com/global-en/support/contact-us/
