About a month ago I noticed that I could no longer tune to my premium stations. After some digging around I noticed that I was also missing many other SDV channels. So, I headed over to the Spectrum office to pick up a new tuning adapter and cablecard. Got them paired up with the Bolt and found that I had the exact same problem - missing stations. I have since switched out both the TA and cablecard again to no avail. Same problem. I need to mention that my life-timed Bolt TA/cablecard setup was stable for a year. Prior to that, I was using the exact same cablecard and tuning adapter for my Premiere for 8 or nine years. I've had 3 Spectrum truck rolls and the techs have not been able to diagnose a problem. My signal strength values from the TA and cablecard are within the "normal" range. One last interesting observation: my Bolt can "see" some of the SDV channels when the TA is not connected to the Bolt (unfortunately not my premium stations). I actually get fewer channels with the TA connected... I am beginning to wonder whether my lifetimed bolt has a problem or whether the issue is something on Spectrum's end. How do I diagnose whether it's the Tivo?
