Just recently I have noticed that I cannot tune to my extra HBO and SHOWTIME channels, both 200 series and 1200 series channels. My trouble shooting has been limited to rebooting my Series 3 TiVo and the attached Tuning Adapter (TA). It seems the TiVo recognizes the TA since it shows up in the menu when it is plugged in and it complains when I unplug the TA. The reason I think I have a problem with the TA is because there is no green light on the front of the TA. Usually there is a glowing green light on the TA but it is no longer there. When I unplug the TA the green light comes back as a flashing green light but after 15-20 seconds the light disappears. Has anybody else experienced something like this? I have not called Cox San Diego yet as I just got around to trouble shooting this tonight and I do not have time to be on the phone with them tonight. I will probably call tomorrow but I wanted to check in here to see if anybody else has had a problem with their TA. Thanks for the information.
