    Need help picking correct capacitor

    I have a cheap 32 inch tv that has trouble turning on. It takes 3 or 4 trys to turn it on in the morning.

    I removed the back cover and discover 3 bulging capacitors. There are 2 purple capacitors labled as 680uf 35v with a number CD286C on them, and one green capacitor labeled 1000uf 25 v and a number CD286 on it. Both have a logo that says YST and F6 printed on them. I measured them and the 680uf 35v was 12.5mm Diameter and 22mm tall, and the 1000uf 25v was 10mm Diamter and 20mm tall.

    I looked for replacements and found these on digikey.com.

    Will these work?

    EEUFR1V681
    EEUFR1E102 <<< NOT "L" version on either of these.

    what other caps does it have? specially small ones.
    better to not have to open it again!

      I completely agree. I was only going to replace the larger caps on my TV power supply board because 3 of the large ones had 'popped' But I feel I was convinced to replace all 16 on my PSB from experienced members here.

      If you notice as you are selecting a cap, they have life ratings. So, every cap in your entire system is the exact same age and they could go in a day, a week, or a year later. Better to be safe than sorry. I have realized how dang cheap good caps are, I'm surprised companies actually use inferior quality caps. Is it so that we buy a new TV or AV receiver every couple of years?

        So i need two of these.
        http://www.digikey.com/product-detai...514-ND/2504783

        And one of these right?
        http://www.digikey.com/product-detai...?enterprise=44

        So it shouldnt matter if they are not the exact same size (diameter and height) as long as they aren't bigger than the old ones?

        Also I wrote down all of the capacitors on what i assume is the power supply here they are ( the measurements are as close as i could get them )

        2 - 680uf 35v ( above )
        4- 1000uf 25v ( above )

        2 - 470uf 35v 10 mm dia x 17 mm height
        2 - 470uf 25v 7 mm dia x 15 mm height
        1 - 47uf 50v 6 mm dia x 10 mm height
        1 - 22uf 35v 5 mm dia x 11 mm height
        1 - 4.7uf 50v 5 mm dia x 10 mm height
        1 - ( label was on other side and couldnt see) 16mm dia x 30 mm height

        I also wrote down the ones on the other board ( I assume the audio )

        Here are some pics

          Here is the link to the spec of the PANASONIC Caps, just get the size and value you need then type in the PANASONIC part numbers into the search box of Digikey.

            Re: Need help picking correct capacitor

            Ok I have been looking at the datasheet and I think I have it figured out.

            A question I have though is what does a Y or L at the end of the part number mean.

            Example, what is the difference beside size and endurance.
            EEUFR1E471Y
            EEUFR1E471L
            EEUFR1E471

            Stj said not to get a L version, but the endurance hours are higher on the L and Y. Should I just stick with EEUFR1E471 even though it has the lowest endurance hours?

              The one without letters is the default model, which is 10 x 12.5 mm.

              L is 8x20 mm , Y is 8x15 mm ... so the L version is taller.

              Taller means more resilient to temperature, hence the higher temperature rating.

              You have the datasheet here: https://cdn.badcaps-static.com/pdfs/...6eee785988.pdf

              My advice, pick any version you want, whatever is most convenient and suitable. With the lifetime rating these have, you'll replace whatever you fix before these capacitors will fail.

                L are longer, look atthe size of the different ones in mm

                  Longer or taller, different words, same meaning.

                    Thanks for the help everyone I appreciate it.

                    One more question, one of the capacitors i need is out of stock.
                    This one here.
                    http://www.digikey.com/scripts/DkSea...50160248686606

                    Would one of these one be a suitable replacement?

                      can always use MFG part number from digikey and buy from Mouser, or buy them here. I bought some of mine from badcaps.net . I should get them in the mail today
