Wondering if anyone has run into this before: I bought a Roamio and sold my Premiere to recoup some of the dough. When the buyer received it, he reported this problem: >>The channels are listed under the program guide, but all channels are blank but for the message "Searching for a signal on this channel." I have run the complete setup twice and separate channel scans numerous times. I only have the basic analog cable package but do get 6 HD channels through the Clear QAM broadcast. Those channels are there and look good. My old Tivo HD Series 3 displays all channels properly, plus when I connect the cable directly to the TV, all channels are there, so this is not a problem with the signal not being present from the cable provider.<< I had only used the Premiere for OTA, so never had occasion to use the cable tuner. Does this sound like the cable tuner is hosed, or could there be some other cause? If his Series 3 works fine with the cable signal, I would think the Premiere would be fine as well. Any thoughts appreciated!
