If your Amazon Fire Stick is not working properly, there are a few things you can do to try and fix the issue. The first is to try a different HDMI cable. If that does not work, you can try a reset. To do a reset, you need to go to the Fire Stick’s settings, select “About Fire Stick,” and then tap on the “Reset” button.
If that does not work, you may need to reboot your Fire Stick. To reboot your Fire Stick, press and hold the power button for about 20 seconds until the Fire Stick turns off. After your Fire Stick has turned off, press and hold the power button for about 10 seconds to begin the reboot process.
