1. Definitely not related to subscription status.
2. Could be a hard drive problem.
3. Could be a power supply or cooling issue.
For the few minutes that it remains powered up, check the temperature on the "System Information" screens. Try to check it frequently to see if it rises into the danger zone(it will say so in system info). Check the back panel(or remove the cover) to ensure the cooling fan is spinning. If you decide to remove the cover, check all the internal connections, especially the hard drive, to make sure they are secure.
If you are comfortable with it, remove the hard drive and check it out. It should be a Western Digital 160 GB av drive. Also, if comfortable, go to www.mfslive.org, read and learn hot to save a backup image of the Tivo drive, while it is still working. If it turns out the drive is/goes bad, you will have the image to restore(install) on another replacement hard drive. If you happen to have a spare, working hard drive, all the better.
Whatever, run the drive manufacturer's diagnostic test scan on the suspect drive. This can be downloaded from the drive manufacturer's web site. If it fails the test outright, that is probably the issue.
If the drive and fan check out to be ok, then suspect the power supply or motherboard issues. Mother board issues are rare. Power supply issues do not seem to be too common with the Tivo HD, but it is still a possibility. Not impossible to self replace, or repair, but may require more skill and resourcefulness.
Hope this helps. Good luck.
