Hello, Please postback with the model number off of the back of the TV.
Reason being is some Panasonic sets actually need the Inputs "Named" or "Labeled" in order to be able to access them.
Additionally the Fire Stick also needs to be connected via USB to a power source in order to power up. Your TV will not let you access the port if there's not a signal detected.
Please first try this- Shut your TV off and unplug the Fire stick.
Make sure the micro USB port on the Fire stick is connected to either a USB port on the TV, or to a USB wall adapter for power.
Then plug the Fire stick into the TV's HDMI port (whichever port is available).
Turn the TV on after everything is connected and then look for the following button on the Panasonic remote:
If that does not work then I will need the full model number off of the back of the TV.
