Question:

What should I do if the Mac Address Test fails during the Network Test?

Answer:

 First, perform a Factory Reset on the TV. Then, run the Network Test again. A Factory Reset resets all TV settings (like brightness, contrast, volume, etc.). To do this:

With the TV on, press and hold the EXIT button on the remote for 10-15 seconds.

After 10-15 seconds, a message will appear saying all settings will be reset. Use the Left Arrow button to select OK, then press the ENTER button. The TV will turn off itself.

Turn the TV back on and follow the onscreen instructions for initial setup.

Run the Network Test again.

If the Mac Address Test still fails, the TV needs repair. Click "Create online Service request" to get help fixing the TV. If the Mac Address Test passes, but another test fails, return to the list of Network Tests. If all tests pass, the TV is connected to your network.
