Auto channel scan locked

[glen.bevan]

I have an Hitachi plasma tv in which I can’t get channels to load. I try to do an auto scan in systems but this appears to be locked ( can’t click on the option because it’s not highlighted)
Any help appreciated

Check if the correct input is selected. If this is connected via HDMI or TV only. Press input on the remote to choose the correct source. Then, open the on-screen menu and select TV or Tuner option then highlight the tuner mode and select the right option.
