Appreciate all the valuable information I have learned here. Anyways, my Tivo HD goes offline every few days. Rebooting the Tivo fixes it. I assumed it was the power supply issue that was mentioned frequently on the forum. I inspected my power supply and saw that in fact two capacitors were bulging. I replaced them this past Sunday. I checked my Tivo this morning and there was no display coming from it again. Do you think I should just replace all the capacitors or could it be something else causing problems. I do have a WD Expander plugged into it as well. Thank you in advance.
