    DirecTiVo Power Supply Caps

    New here...

    I've got a few DirecTV Phillips DSR704 TiVo's that have failing power supplies, so I'm at the point of replacing all the electrolytic caps - but am not sure what to order for replacements. Below are the original supply values (all are 105deg):

    C9 - 47uf / 50V (Teapo SEK)
    C14 - 2200uf / 10V (Ltec LZG)
    C15 / C20 /C42 - 470uf / 10V (Ltec LZG)
    C17 - 2200uf / 10V (Ltec LZG)
    C18 - 2200uf / 16V (Teapo SC)
    C23 - 470uf / 50V (Ltec LZG)
    C26 - 47uf / 63V (Teapo SEK)
    C27 - 1uf / 50V (Teapo SEK)
    C29 - 10uf / 50V (Teapo SEK)
    C34 / C35 - 2.2uf / 50V (Ltec) - unknown series (tiny black cap with gold banding and lettering)

    Any help or pointers would be greatly appreciated!

    If Panasonic caps meet your requirements, follow PlainBill's instructions at

      you need to add the diameter of each cap if they are tight together.

        I was going to go back and add dimensions but it was past the time to edit. Unless I'm missing something it looks like the Nichicon PW series caps will work for all of them (someone correct me if I'm wrong). Although not sure about C34/35 as I'm not sure what series those are to begin with.

        The ones that I've selected that seem to be a best match:

        C9 - 47uf / 50V (Teapo SEK) - 6mm x 12mm : UPW1H470MED
        C14 - 2200uf / 10V (Ltec LZG) - 13mm x 20mm : UPW1A222MHD
        C15 / C20 / C42 - 470uf / 10V (Ltec LZG) - 8mm x 12mm : UPW1A471MPD
        C17 - 2200uf / 10V (Ltec LZG) - 10mm x 30mm : UPW1A222MPD6
        C18 - 2200uf / 16V (Teapo SC) - 13mm x 25mm : UPW1C222MHD
        C23 - 470uf / 25V (Ltec LZG) - 10mm x 16mm : UPW1E471MPD
        C26 - 47uf / 63V (Teapo SEK) - 8mm x 12mm : UPW1J470MPD
        C27 - 1uf / 50V (Teapo SEK) - 5mm x 12mm : UPW1H010MDD
        C29 - 10uf / 50V (Teapo SEK) - 5mm x 12mm : UPW1H100MDD1TD

        C34/35 don't have a series on the cap, but I'm guessing since all the Ltec caps in the original supply are LZG series that the PW series would be fine for them as well.

        C34 / C35 - 2.2uf / 50V (Ltec) - 4mm x 6mm : UPW1H2R2MDD

        These are a bit bigger but where they are located, should have plenty of room.
