Charging Problem/Red Notification Lights

[kiwi_son]

I've no idea why this is happening right now but my phone won't charge.
When I plug it in the red notification light blinks for a while, then the charghing logo appears on the screen for a short time and during that time red is light constantly lid, as it was suppossed to, however then the screen goes black again and the light starts blinking.

I found a solution on YouTube which suggested me to tape power button firmly so it's always pushed and then charge it for an hour. I did exactly the same thing, nothing changed.

It's been more than 2 hours and my phone is still charging with the same cycle (blinking red light, then charhing logo, then blinking again).

I wonder what happened to my phone and what can I do now?

Thanks in advance!

EDIT: I realised that with using charging dock I can see a glimpse of Xperia and Sony logo but then they vanish. The phone seems to be restarting itself while I use the dock.

Well i think there must of been some leek and water did enter your device. Not much but still. If you seen steam on the camera lens then it mean its a water damage. However if you are sure you closed all flaps perfectly it should be a faulty device. I recommend you sending your phone to Sony but first contacting them. If you don't want to wait a month tho,  then your only help is a bowl of rice!
