TCL Customer FAQ

To resolve calling issues on your TCL 20, first check your network signal strength and ensure your phone is not in Airplane Mode. Restart your device and make sure your SIM card is properly inserted. Verify that your phone plan is active and not restricted. If the problem persists, try resetting network settings in the settings menu.

It seems like you're experiencing a color display issue with your TCL TV. This could be due to a variety of reasons like incorrect color settings, cable connections, or a software glitch. Firstly, check your TV's color settings from the picture mode and ensure they're set right. If the issue persists, try resetting your TV to factory settings. Disconnect and reconnect the HDMI or AV cables to ensure they're properly connected. If your TV is still displaying in reds and blues after these steps, it might be a hardware issue requiring professional assistance.

This could be due to several reasons. The issue might lie within the location or orientation of the antenna connected to the TCL TV. Obstructions, weather, and distance from the broadcasting station can also affect reception. Try repositioning or relocating the antenna for better reception. If that doesn't work, perform a channel scan on your TCL TV to see if it then picks up the network station. If the issue persists, consider resetting your TCL TV to factory settings, though this will require you to set up everything as if it were brand new. Lastly, if none of these suggestions work, your TV could be experiencing hardware or software issues that need professional attention.
