Gregory Herrera, this is a know error with that type of phone. First thing I would try is a new cable. It is possible that the cable end is not making proper contact. If that does not work, you will have to disassemble your phone and replace the connector. the ports are available at places [http://www.wirelesspartsinc.com/htcmytouch4gbattery-1-2-1.aspx|like this] and require soldering onto the circuit board. Hope this helps, good luck.
