If the indicator doesn’t light up on the Mi TV 4A 55, please refer to the following steps:
1. Make sure the TV is properly connected to a power source. Check the power outlet and ensure it is functioning. Try plugging another device into the same outlet to verify;
2. Make sure the remote control is working correctly and has functioning batteries;
3. Try turning the TV off and then on again to see if the indicator light lights on;
4. Turn off the TV using the power button, unplug it from the power source, and wait for a few minutes. Plug it back in and turn it on. This helps to reset the TV and may resolve minor glitches;
5. Check if there are any physical issues with the indicator light itself. Make sure it's not damaged or obstructed. If the indicator light itself is not functioning or there are any signs of physical damage, it can be a hardware issue;
6. If the issue still persists, please update the firmware of your TV by navigating to [Settings] >> select [Device Preferences] >> select [About] >> select [System update];
7. If all these methods fail, please reset your TV to the factory default. Navigate to [Settings] >> select [Device Preferences] >> select [Reset].
If the above troubleshooting methods can’t resolve the issue, please contact our local official service center or your seller for further assistance. They will help you in this regard.
