Slow charging, red light blinking when phone is OFF.

Hey.

I have a problem with my phone.

The phone is charging very slowly (150-300mA)

If the phone is switched off and connected to the charger, the red LED blinks and can not be switched on.

The phone only starts when I disconnect it from the charger.

PC does not detect the phone. After connecting to the PC there is no reaction.

I have already replaced the USB board. It still does not work.
