Thought I would post this for informational purposes. I have had two problems with my old Phillips series 1 TIVO with lifetime license/membership. The modem stopped working a few years ago. Just today the receiver (apparently) stopped working. The TIVO worked in both cases, but the functionality for the particular area did not. I tried multiple resets both times. No luck. Both times I was able to correct the problem by removing the cover and using canned air to blow all the dust off the mainboard, connectors, etc. Just something to try before going to more drastic measures. Thanks for all the useful info posted.
