Amazon Fire TV troubleshooting: issues from network to app to HDMI.
Fire TV problems usually start at the stick or the cable: a remote that will not pair, a screen with no signal, a stick stuck on its storage message, or apps that freeze. Find the symptom, then try the network and HDMI checks before a factory reset.
Fire TV apps freeze, crash or will not open
Force stop the affected app, clear its cache, restart Fire TV, and update the app and device. Clear app data or reinstall only if you know the service credentials because either can sign you out. Check Settings, My Fire TV, About for a pending system update, since crashes often follow an update that never finished.

Use fresh batteries, move the remote within range, restart Fire TV, then hold Home to pair. Remove nearby devices that may interfere and use the Fire TV mobile app only as a temporary same-network remote. A remote that works for a moment and then stops usually needs new batteries, even if the ones in it seem new.

Select the exact HDMI input, reseat Fire TV and its power adapter, restart the display, then test another HDMI port. Connect directly to the TV before blaming a receiver, switch or soundbar. Press the TV's own input button until the Fire TV logo appears, which proves that the TV can receive the signal.

Allow the first optimization cycle to finish on stable power. If it repeats, remove USB accessories, restart the device and power source, then check free storage and software; do not interrupt every boot or immediately factory-reset.
Open record Fire TV · Wi-FiFire TV will not connect to Wi-Fi
Restart the Fire TV, verify the Wi-Fi name and password, restart the modem/router, and move the device closer. Forget and rejoin the network only after another device proves the internet connection works. A Fire TV that finds the network but has no internet usually needs the router restarted, not the stick reset.
Open recordTroubleshooting a Fire TV
A Fire TV stick or box restarts from Settings, My Fire TV, Restart, or by unplugging the power for 30 seconds. Keep it updated under Settings, My Fire TV, About, Check for Updates. If the remote stops working, remove the batteries, unplug the Fire TV, plug it back in and press and hold Home for about ten seconds to re-pair.
Apps that crash usually benefit from clearing the app's cache and data under Settings, Applications, Manage Installed Applications, and from freeing storage, since Fire TV sticks have limited space. For buffering, test the network speed under Settings, Network, and move the stick to the HDMI extender in the box to reduce interference from the TV. Power the stick from the wall adapter rather than the TV's USB port if it restarts randomly.
