Why does my LG TV have sound but no picture? If you hear sound but the screen is blank, LG’s support page lists a few checks to run. This article follows that page, LG TV has sound but no picture. We haven’t tested any TV.

Why Does My LG TV Have Sound but No Picture? The Causes LG Lists

LG says the issue may be caused by a signal problem from an external device, a loose connection, or a faulty HDMI cable. It lists three causes: the device is temporarily frozen or isn’t sending a video signal, the cable between the TV and the device is loose or damaged, or the TV itself has an issue.

Step 1: Run LG’s Volume Test

This test checks whether the issue is with the TV itself or an external device. Press the Volume button on the TV remote. If the volume indicator appears on screen, LG says the TV’s display is likely working fine. Use the TV’s own remote: changing the volume with an external device’s remote makes the test inaccurate. If nothing appears, LG’s FAQ says there may be an issue with the TV itself and advises contacting LG Customer Support.

Step 2: Restart the External Device

Turn the external device off and back on, or unplug its power cord and plug it back in. If the picture then appears normally, the issue was likely a temporary error with the device, according to LG. If the issue happens frequently or the picture still doesn’t appear, the device may need to be serviced.

Why Does My LG TV Have Sound but No Picture? Reconnect or Replace the HDMI Cable

Disconnect the HDMI cable from both the TV and the external device, then reconnect it firmly. If the picture appears but the problem comes back, LG says the cable may be faulty and suggests trying a new HDMI cable.

If the Problem Continues

If the issue persists after these steps, LG says you can get further support.
