Well I certainly apologize for it not working. I love caller ID and I know how frustrating it can be when it doesn't work! Bear with me, and let's see if we can fix this. First, has it ever worked? I'm not trying to make you look bad but these are stupid (but important) questions. Next, can you plug a live phone into that outlet to test the line itself? Next, go through the settings. Menu - Extras - Caller ID. Notices should be 'on'. If they ARE turn them 'off', unplug the phone line from the receiver, UNPLUG receiver (better reset) for 15 seconds. Plug back in and let reset, plug phone line back in, and set notifications back on. In VERY rare circumstances the phone jack 'can' go bad, but it's highly doubtful. I really hope this fixes the issue for you. Let me know!!
Enable/Disable 1.From either the receiver's quick or main Menu or the receiver's System Setup menu. 2.Select TVmail & Caller ID, Calls & Msgs, or Caller ID, depending on the option displayed. 3.Turn Caller ID, Calls & Msgs, or Display Caller ID on or off as necessary. For caller ID to be on your receiver should be displaying NOTICES: Off (which means caller ID is on) IF that's what your receiver shows and still not working and you subscribe to caller ID with your phone company, disconnect the phone cable form the back of the receiver, Now press the red reset button; once your receiver is back up, reconnect the phone cable - resolve issue 99% of the time - if still not working and you want that feature - you'll need to call into technical support 1-800-531-5000 for possible replacement of your receiver
