Question [HELP / HTC MyTouch 4G] NOT charging problem

Hello everybody. I have a HTC MyTouch 4G and I have a charging problem.

When I put my phone to charge, it discharges like no charger connected.
The phone shows charging animation and led but nothing is happened.

I've tried: charging via usb (with several cables (Motorola, Samsung, BB)), via wall-charger (5V/1A and 5,7V/2A) of several brands like Samsung, original HTC, BB, Alcatel.

The problem happens with all roms (I've tried with Stock GB Rom, also with Stock Froyo Rom and CM 4.3) / even with phone turned-off and in recovery and fastboot mode.
Without results

The phone doesn't charging at all, I'm sure that this is a hardware-related problem. Any can help me??
Thank you so much
