Tivo still crashes after replacing two capcitors

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.

Yes, bulging means they had to vent. They can be bad without the venting.

And yes, expanders can cause these problems as well. Which size is it? You sound clever enough to just upgrade the internal to have one less point of potential failure...

adding to what jrtoo said.
Even though they can be bad without bulging, I have noticed they fail in waves by manufacturer, so if any were the same brand as your bad ones, they would be on my "replace no matter what" list, but I'd consider replacing most of the larger and mid-size caps anyway.

Replacing Hard Drive and Capacitors

I am going to replace the remaining capacitors on the power supply.

I am also going to install a 2TB drive in the Tivo as well. Just to cover all my bases.

Replacement caps should be low-ESR types with a temp rating of 105C, or they won't last long. Parts lists for various tivo models have been posted on this forum. Mouser is one good place to get them.

The really big one rated around 200V is probably just fine.

And the really little ones probably are as well.

Just worry about the ones clustered around the heat sink.

And get a WD20EURS if someone's got new retail ones for $100 or less.

But work on one problem at a time so as not to introduce too many variables at once.

And check your video output with the yellow jack, not the 3 component jacks or the HDMI.
