I purchased a Pioneer PDP-4280 on 9-10-2007 and it's been great! A couple of months ago though I noticed that the TV Guide is not working ... that is it ALWAYS shows "No Listing" and the progress seems stuck on the date 2-6. I tried turning off overnight ... no luck; I switched from Antenna A to Antenna B and still no success. I've gone through the setup process for the TV Guide many times with the same results ... no listings. Now - I can get to the channel I want by scrolling down or using the controller but something is broke .. or else I just don't know how to reset?? I live in Boise, Idaho. Do I need service and can I even get service??
