Its been a long time since I've posted but alas my TIVO HD has taken a turn for the worse and I want to repair it but I'm having a hard time figuring out what capacitors I need to replace. When I look around no power supplies look like the one I have.

Bigger yet the 3 green caps in the photo are slightly convex and I want to replace but I cant tell what parts I should order on Mouser as the picture on mouser looks completely different from what the tall green capacitors look like.

Any help would be appreciated.

I have never seen that supply all I can tell you is all the caps close to the heat sink needs to be replaced. I think I saw a couple 2200mfd @ 16v
100mfd @ 16v 100mfd @ 6.3 the two 2200 @ 16v looks bad. The few at the front hardly ever go bad there small and very low voltage. If you could get a few more Pics in sections I might be able to read the caps you need to order. Are I can login to mouser and put in a cart save it and send you the link.

Thanks Tim! From what I could tell the(3) 2200@16v appear to be convexing and 1 about to start leaking.

As far as the blue caps the 1000@6.3v and 1000@16v do you think those are starting to go bad? If so could you explain to me why. I am asking this from a learning perspective not critiquing your knowledge and experience.

Thank you!!!

It only looks like it's the 3 2200Mfd @ 16VDC that needs to be replaced.
Let me go put them in a cart at mouser and post the link to the cart.

This should bring you to the cart

http://www.mouser.com/ProjectManager...sID=39f187698f

It's a shame it will cost you more to ship them then the cost of all the caps you need. If you have some other projects you need parts for it would be a good time to order.

Fortunately this is the only project I need to attempt this on! I'm glad you knew the exact cap as I was going to order the 10x20mm by 2200@16v from the list that was setup on the previous page.

How many different boards do they have for this unit?

But they look alike that was kind of a shock "no pun intended" I was thinking it was a series 2 but I'm sure you know it's a series 3 HD I guess that old saying is true you can teach a old dog a new trick..
Make sure you put the ground side on the side with the hash marks
since you have some good pic's to fall back on you should have no problem...

LOL.

I also saw in your previous post that the large cap should be looked at or even replaced? Mine says Elite 470uf200v. Whats your take on this and if so would you mind shooting me another link for purchasing.

This year and only replaced 3. If there is no goop on the bottom it's good. Those caps will vent from the bottom and trust me it's a mess to cleanup. Yours look good so I would just replace those 3 that are wearing there caps....
If you run into trouble hit me with a PM and I will see what I can do for ya.
