I can not find an HDM1 port on my Sharp TV. Can I use the USB Port?

No, the HDMI plug will not fit into a USB port. (It's the wrong shape and the pins are different.) The micro-USB port can be connected to some USB ports for power, not data, with the appropriate cable (micro USB to type A). (Without the model of your Sharp TV, I do not know if the USB port has the right specifications. Some older TVs only have a "service port" which doesn't always provide enough power.)

There are HDMI to component video/audio converters that may work. They do not always work with copy protected (HDCP) content. See http://www.bhphotovideo.com/c/product/770115-REG/KanexPro_HDRGBRL_HDMI_to_Component_Converter.html for one example. (Composite video is not recommended since that will downgrade the signal to 480i. Component video supports 1080p signals.)

If you have 1 HDMI port, then a multi-port HDMI switch may work. Note: automatic switches often do not switch on their own with some sources. If the source never actually turns off, like some set-top boxes, you'll need to switch the unit manually.

I hope this helps.
