My series 3 Tivo box drops the input signals, cable and antenna, and displays the searching for signal gray screen every few days. All problems seem to start from tuner 0. Screen interferance shows up after reset on tuner 0, not tuner 1. Digital signals are ok. In a few days frame bars between frames start on tuner 0 also. Then tuner 0 starts dropping signals on all analog chanels.
Restarting clears everything up for a few days or a week. Check of cable and antenna signals are fine when Tivo problems start showing up.
Is this a problem anyone else is seeing?
