To compress this story as much as possible, back in March I got my parents a TiVo Bolt Vox to use to get OTA channels and streaming services. It worked for about 2 months before it had a sudden and catastrophic tuner sensitivity failure. After much troubleshooting and getting insistent with Support, they were sent a refurb replacement for their Bolt. The replacement worked for 6 weeks, and three days ago it started exhibiting the same behavior-- only the strongest signals come in, and everything else suddenly and catastrophically failed. Other TVs and tuners in the same house still "see" all the channels they saw before at the same signal strength as before, and only the TiVo's behavior has changed. I'm sure replacing it again would fix the problem again, temporarily. No, there hasn't been a repack. Yes, they've scanned for channels again anyway. I can't keep going through the setup song and dance remotely for my parents every couple months, so I'm curious if anyone else has experienced repeated reliability problems with the Bolt series, specifically with the Bolt Vox 500 GB. Cursory searching seems to indicate they have some heat-related problems. Has anyone else gone through multiple replacements with TiVo, and if so, did you ever get one that worked consistently and continually?
