[LG TV] Troubleshooting an LG TV With No Picture and No Sound

If there is no sound or picture, first make sure the TV is turned on. Then press a volume button on the remote control to check if the volume bar appears on the screen.
If the volume bar appears, the problem may be with the external device or cable connections.
If the volume bar does not appear after pressing a volume button, there may be an issue with the TV itself.
If the "No Signal" message shows, check the input mode and make sure the connected external device is turned on.

First, check the standby light.

Is the standby button turned on?

If the standby light is turned on, it indicates that the TV is not turned on.
If the standby light is turned off, it indicates that the TV is turned on. Turn off the TV and check if the standby light illuminates.

Does the screen show the message ‘No Signal’?

If the ‘No Signal’ message appears on screen, it means the TV is not receiving a signal from the set-top box or service provider.
In this case, the set-top box may require inspection. Please contact your service provider for assistance.
If the TV is turned on but no message or picture appears at all, there may be an issue with the TV itself. This may require further diagnosis by an LG professional.

[Wired cable connection]

Press the remote control Home Hub [] button or the External Input [] button and select Live TV.

[Set-top-box or HDMI connection]

Press the remote control Home Hub [] button or the External Input [] button and select the connected HDMI port.

Does the TV turn on, but the screen stays black? (No picture)

To check if the volume bar appears, use the remote control to adjust the TV volume.
※ If the volume bar appears normally, the issue is likely with the set-top box or cable connection.

Reconnect the cable connected to the TV or reset the set-top box.

1. 1. Unplug the set-top box power cable and reconnect it after five seconds.

   

2. 2. Unplug the router power cable and reconnect it after five seconds.

   

3. 3. Reconnect the cable securely into the correct ports to prevent any connection issues.

   

4. 4. Similarly, reconnect the set-top box HDMI cable.

   

5. 5. If the issue continues after following the steps outlined above:
   If the TV is turned on, and the message ‘No Signal’ is shown on screen, the problem may be with the cables or external device.
   Inspect the set-top box or other connected devices.
   If the TV is on but the screen remains blank with no messages, the TV may require professional inspection.
