I have a "new" (refurb) Premiere. I have not as yet installed a CableCARD but have it configured for both OTA and Cable (accessing the clear QAM channels). About 3:30AM today, Comcast had an EAS test. No problem, I just had it on for background noise. It was tuned to the local OTA sub-channel that carries Antenna TV. The EAS test forced it to the cable WGN channel as normal and I got the alert sound which prompted me to mute the sound and of course got the announcement crawl. 15 mins later, I noticed the crawl was still going. When I un-muted it, the sound was back to normal but the TiVo was still unresponsive. I went in the living room and checked the status of the other Premiere and the THD, both of which have CableCARDs installed. Neither had a problem. Since the Premiere had been in standby, its status didn't eliminate the possibility of it being a general Premiere problem. After an hour in this state, I decided to do a hard boot of the TiVo. When it came back up, no problem.
Beyond actually reporting this to TiVo, does anyone have any ideas or suggestions?
