    Help with ordering caps.

    I am working on a LG 50PC5DC 50" Plasma. I have found that there are 6 bad caps on the psu, but I am not sure which ones to order. The caps all say VDE PET on one side and WD 10 v 3300uf 105*C (M) on the other. I have added some pics of the bad caps and marked a few others that I was wondering if I should also replace aswell. Red are bad yellow are good but should I replace them. Picture 4 is of the other caps that are not bad.

      This is my standard answer (regulars may skip). It teaches you how to choose caps and what values/parameters are important.

          How do I find out what the ripple and ESR values are on the original caps?

              In your third picture, all the info is listed. The manufacturer is Samwha. The series is WB. Now search for Samwha WB datasheet. This forum may have the datasheet in older posts or it may be on the Internet.

                  Look where the big # 3 is, to the right on screen there is a datasheet for wb series

                  direct link:
                  http://www.samwhaparts.com/pd6-23.htm


                  I think it more looks like the pic says wb series

                      Here's the catalogue :



                      WB was discontinued around '99 - the replacement according to them is the MK series. MK is listed in the catalogue linked above.

                      But you can basically replace with anything as long as the ripple is >= and impedance <= than wb/mk.

                          Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!
                          by momaka
                          I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

                          For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

                          https://www.badcaps.net/filedata/fetch?id=3591772

                          It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

                          Identifying caps on an old Zoom 9000
                          by Paxman_Swede
                          Hello!

                          I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.

                          The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

                          I have studied the board and...

                          Caps and how to find one to replace
                          by edith
                          Hello everyone I have a question. I have a laptop and his schematic. Can anyone tell me how to measure or any way to understand specific of caps so i can buy new one?

                          Also in case how can I understand if some caps of some dead Mobo i have, are ok to be replaced in my new motherboard which im trying to fix?

                          Thank you!

                          Gigabyte GA-6OXT :: caps question
                          by Foetuss
                          Good evening

                          I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
                          Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?

                          But I was also suprised about the bigger boys, which are 330µF 25V.
                          Could it be they used 25V caps because they were cheaper / available at that time?...

                          Which caps to replace: ECS P4M800Pro-M V1.0A
                          by Mattz_GT
                          It's feeling like this board has a case of badcaps, instability and reboots - and not wanting to necro a a very old thread, it seems the 680uF 4V are highly suspect.
                          I don't really want to blanket recap everything, but maybe the others around that area could do with being changed?

                          Equipment: I have a temperature controlled soldering station, read the bit where it says set to 400F, don't think I would have gone that high without reading that.
                          Spring plunger solder sucker, and some desolder braid... and a bit of good old leaded 60/40.

                          PS. Additional diagnostic,...
