When applying a picture test, the TV will show a pattern from which is already uploaded in the firmware; this pattern is unrelated to any connections or inputs.

1 Test the HDMI cable.

To perform the test, make sure the TV's source is still on the HDMI setting for the cable you want to test, and then navigate to Settings. Select Support, select Self-Diagnosis, and then select Signal Information. Select HDMI Cable Test, and then select Start Test.

If the test says the cable is bad, replace the cable. Service is not required.

2 Test different external devices

Try connecting a different device or using a different source port. If you were unable to test the cable in the previous step, then try swapping the cable too.

If the TV can display a picture in any other setup, then the TV is not the cause of the issue. Keep trying various setups until you identify the device or cable that is not working, and then troubleshoot or replace it.
