Tivo Bolt OTA worked perfectly for about 45 days. Then occasionally the picture crackles (green pixelation, and then just black). Audio cuts out at the same time. Each blip lasts a fraction of a second, and gets longer over the course of a minute. Accessing Tivo internal menus as screens cuts out as well, so it is not the OTA feed. Typically it blips on and off a few times over 20-30 seconds, and then it all just goes black and quiet. My (painful) work around is to unplug the Tivo power for 10-30 seconds, plug it back in, and then it works fine again for a few days. What is wrong with my new Tivo Bolt ?
