We have had a number of inquiries from Series3 owners reporting frequent rebooting and restarting. This problem sometimes occurs after a power outage or after the Series3 has been powered down. It sometimes happens with units that have off-air antennas attached. Here are some suggestions for solving the problem; please post your experiences.
1) If your TiVo has CableCARDs, and if it has been working fine but suddenly starts rebooting/restarting, please try the following:
A. Unplug the TiVo and remove the CableCARDs. Be sure to note which card came from which slot. The cards are NOT interchangeable.
B. Power up the TiVo without the CableCARDs installed.
C. The TiVo will display a message saying that your setup has changed. Go to the messages and setup / system reset menu and choose Repeat Guided Setup. Set up the TiVo with cable WITHOUT CableCARDs.
D. Insert CableCARD one onto the bottom slot and navigate to the CableCARD configuration screen. Once your CableCARD is authorized (or once you are able to see a digital/scrambled station in LiveTV), repeat the process for card 2.
E. Once you have both cards authorized, then repeat Guided Setup, telling the TiVo that you have cable with CableCARDs.
2) If you have an off-air antenna and your unit reboots (especially if the rebooting occurs with specific channels), you might try unplugging the antenna and see if the problem resolves itself.
