There has been a great deal of forum activity on this subject recently, but, IMO, specific details of each individual user's situation are not being presented.
Listed below are the reasons that I am currently aware of for a ReplayTV 5XXX to reboot. We don't have an entry for this in the FAQ, so, with this 'flurry' of activity (more hands make light work), I'd like to try to compile a proper 'Troubleshooting Checklist'.
Please reply if:
You have another reason / checklist item to add.
You have a correction for an existing reason / checklist item.
You're aware of a LINK in the AVS Archives discussing an item already on this list in detail.
This is a "Work-in-Progress" Document!
