How do I fix a TCL TV that will not turn on or has no volume?

Follow these steps

1. 1

   Power-reset the TCL TV

   Turn the TV off if it responds, unplug the power cord from the wall, wait at least 60 seconds, then plug it back in and press the TV’s physical power button.

   You should see: The TV powers on, or the status light shows a clear power response.

2. 2

   Test volume on the TV itself

   With picture on, use the TV’s volume buttons (not only the remote). If the on-screen volume bar moves but you hear nothing, also check Mute and any external soundbar power.

   You should see: Volume changes on screen and sound returns, or you confirm audio is routed elsewhere.

3. 3

   Select the correct HDMI input

   Press Source or Input on the TV or remote and select the port your device uses, often HDMI 1. Power on the computer or streaming device after the TV input is set.

   You should see: The connected device’s picture and sound appear on the TCL TV.

4. 4

   Recheck cables if the screen stays blank

   Reseat the HDMI cable at both ends, try a different HDMI port, and confirm the source device is awake. Repeat the power reset once more if needed.

   You should see: Picture and audio work on a known-good HDMI path, or you have isolated a bad cable or port.
