I have 3 fire sticks - the first purchased over a year ago working fine. Purchased a 2nd generation in September and it now won't connect. For a couple weeks it would either completely disconnect while watching or constantly restart. Now it's completely dead. The old Fire stick works in the same tv though - possible that it's the power cord port itself is the problem? Power cord worked when I tested it with the other fire stick. If I'm outside of the warranty can it be "fixed" or do I need to just get a whole new fire stick?
Did you try using the power cord from one of your other FS on the dead one? Or, did you try using the dead one on another TV? Did you try changing the batteries in the remote to see if it can connect to the FS?
If you’ve tried various maneuvers to get it to start up and nothing is working, it might be time for a new one. But first, contact Customer Service and they will troubleshoot with you. From any Fire TV menu, go to Settings > Help > Contact Us, make your selections and Amazon will call you almost immediately.
