    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.

    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.

    I worked on a couple of those boards. Tivo had two different versions for that model. One trick to consider when you are de-soldering the old cap: the old solder is hard to melt, but if you add some new solder when heating it will dilute the old enough to easily melt it.

    Regards,

    I have 2 dead series 3 oled tivos (one dead, one almost). hard drives are good. got 2 sets of caps from mouser. my nephew removed and replaced the following caps: 667-EEU-FR1e222L-25vdc 2200uF(1 in each TiVo); and 667-EEU-FR0J222-6.3vdc 220uF (2 in each TiVo). I think we are on the right track as w/those replacements, each TiVo lit up and the 'powering up' screen came on; however, all of the lights on the front of the TiVo stayed on. Which would be the next caps to replace, given this scenario.

    w/the soldering iron that he has it takes him quite a long time to get each one done, so we really would just like to know the next ones to replace that might boost the tivos up to the point they will work. replacing all of them just for the sake of doing that is a bit daunting.

    also - if someone has a suggestion of a currently available soldering iron that would work really well with doing this cap replacement, let me know.

    Try putting some fresh solder on the old solder see if that helps. If not go to radio shack and get a 45W pin.
    It sounds like it's a hard drive problem if it stuck on the first welcome screen. You might won't to download a good image file and use winmfs and put a new image but your going to have to clear and delete. Before you do that let me know how many caps you replaced first.

    Just received the caps in the mail. They are not the size of the defective green caps. These replacement ones are short and stubby and therefore wont fit in the board since the green ones are so close to each other.
    Tim please explain to me what I am to do with these.

    Thank you

    Is this the one thats suppsed to go in C14,C17,C27?

    667-EEU-FR1C222

    Power supply's. I bet you can get them to fit it might not look the best but it's going to be in the TiVo. If you would like send it to me and I will get them in and do it free. Send me a PM so I can call you.

    i will let me nephew know about that re the solder and hopefully that will help. it is definitely not a HD issue as I put new HDs in both. one of them had just up and died; the other produced some lines on the screen.

    if I could tell him which cap to go after next, that would help. the idea of replacing all of them I think is a bit overwhelming.

    Replacing all the caps with a good iron should only take 20-30 minutes for someone with little experience. 10-20 minutes if you've done it before. You really should replace all the caps if you have them.
