To troubleshoot power issues on your TCL Fire TV, follow these steps:

Basic Checks

1. Check Power Source: Ensure the TV is plugged into a working power outlet. Test the outlet with another device to confirm it’s functioning.
2. Check Power Cord: Make sure the power cord is securely connected to the TV and is not damaged. Try a different power cord if available.

Restart the TV

1. Unplug the TV: Disconnect the TV from the power source. Wait for about 1-2 minutes.
2. Plug the TV Back In: Reconnect the TV to the power source and try turning it on again.

Remote Control

1. Check the Batteries: Ensure the remote control has working batteries. Replace them if necessary.
2. Use the Power Button on the TV: If the remote is not working, try using the power button located on the TV itself.

Power Cycle

1. Perform a Power Cycle: Unplug the TV and press and hold the power button on the TV (not the remote) for about 30 seconds. Release the button, wait another minute, and then plug the TV back in.

Check for Signs of Power

1. Indicator Light: Check if the standby/power indicator light on the TV is on or blinking. This can help diagnose the issue:
   • No Light: Suggests a power issue; ensure the outlet and power cord are working.
   • Blinking Light: May indicate the TV is in standby mode or there’s a hardware issue.
   • Steady Light: Suggests the TV is receiving power but may not be turning on correctly.

HDMI Devices

1. Disconnect External Devices: Unplug any HDMI or other external devices connected to the TV. Sometimes, faulty external devices can cause power issues.

Firmware Update

1. Update Firmware: If the TV turns on intermittently, check for firmware updates which can resolve software-related power issues:
   • Go to Settings > Device & Software > Check for Updates.

Advanced Troubleshooting

1. Inspect for Physical Damage: Check the TV and power cord for any visible signs of damage.
2. Check for Overheating: Ensure the TV is in a well-ventilated area and not overheating. Overheating can cause the TV to shut down unexpectedly.

Factory Reset

1. Perform a Factory Reset: If the TV powers on but is unresponsive, you may need to perform a factory reset:
   • Go to Settings > Device & Software > Reset to Factory Defaults (if you can access the menu). Please note this will erase any stored information such as passwords/logins.

Contact Support

1. TCL Support: If none of the above steps work, contact TCL customer support for further assistance. Be prepared to provide information on the steps you've already taken to troubleshoot the issue.

By following these steps, you should be able to resolve most power issues with your TCL Fire TV.
