Replacement Capacitors for TV power supply

Hi all,

 

I have a power supply board from an Envision L37W698 HDTV with several blown CapXon KF105 C capacitors and need to find suitable replacements.  it's been a long time since I've done this and there are literally 50 matches for different caps when I enter the info I know from looking at the board.  I have the following I need to replace:

 

2 x 680uF 25v C724

2 x 1500uF 16V C725

3 x 1000uF 35V C725

2 x 470uF 35V C724

3 x 220uF 35V C723

1 x 22uF 16V C705

 

Can someone help finding suitable part numbers from Digikey?

    Hello,

         I just repaired my Viewsonic which had the same problem with the power board.

    All you have to do is pick a capacitor brand name and series an buy all the capacitors from it.

    I used Panasonic FM series which are exelent quality and meet the 105 degree

    temperature range, with great longevity.  I would recomend replacing all the capacitors

    from that side of the board, even if they look fine.  Including the ones under your heatsink on the right

    of the first photo, top left of the second. You never know if they also failed (unless you can test them properly) 

    Usualy you can find "replacement/repair kits" on e-bay for your given board.

    see what they list for your particular model, then buy the replacements here; where you can be

    sure of their quality and freshnes.

     

    What ever brand you get; Make sure you get capacitors rated for 105 degree operating range.

    Be sure to check that they will fit under you heatsink.  Getting them a little bigger is ussualy fine.
