Advertisements TivoHD reboots now maybe once a day. Got refurbished power supply, but that did not help, but indeed there where some bulging caps in my power supply (i had swapped most of them a couple years ago, but probably didn't have all of them at hand back then), so new power supply definitely nice to have. Temperature in settings shows normal (43C). 2 GB WD green disk has only one year runtime, and didn't show any bad sectors, SMART is fine, whole disk copies where fine. Did a factory reset on the box. Unmarked from channel lineup all the channels i am supposedly not receiving (comcast cable), just in case the box has some issues relating to received signal. Wanted to try to disconnect from cable for a few days to see if reboots are related to that. Haven't seen threads reporting on actual motherboard failures. Of course, its aging. How likely could that be a problem ?
