If the color of the video is abnormal when playing the videos from the source of AV/TV/HDMI/USB, please follow the below methods to do the troubleshooting:

1. Confirm if the TV works in the right source mode or not. For example, the TV should work in the Media Player mode if you play the videos from the USB drive.

2. If you use the AV port for the videos, please ensure whether the cable connection is correct. Usually, the AV device will have three ports, two for the sound, and one for the audio. For some TCL TVs, the AV ports combine to one AV port, so check the AV ports connection on the AV video device.

3.  Power cycle the TV. You could unplug the power cord from the socket and plug it back in.

1. Try to restore the TV back to the factory settings: press the Home  button and select Settings Device Preferences Factory Reset.

If the issue cannot be resolved, please feel free to call the TCL hotline for further help.
