Question Panasonic 2007 plasma connecting to firestick

[Alliedog]

When I plug in the firestick to the hdmi port on my 2007 Panasonic plasma nothing happens.

Did you manually select the input port on the TV to match the one the Firestick is using?

Did you connect a power supply to the firestick?
