    Re: The Hall of Shame - Badcaps Photo Montage

    Those are probably Sacon FZ series.

      Re: The Hall of Shame - Badcaps Photo Montage

      Here are 4 photos of the bad caps on the EVGA e-GeForce 7600GS video card. I hope they are clear enough. If they aren't, I'll redo them.

      As I said, when this thing blew up, it took out the mobo too. :-(

        I'll bet you're right.

        So, what should I replace them with? Panasonics? Rubycon? Nichicon?

          Kgordon, Topcat had some similar cards to yours, also with failed Sacon FZ.

            Those are Sacon FZ series. - Complete Crap.
            Sacon = GSC = Evercon. -> New names, same company, same crappy caps.
            The FZ also come with black markings.
            They try to look like Nichicon [black] or Chemicon [blue] Solid Polymer caps but the "K" stamp gives them away as regular lytics.

              Panasonic FM or FJ, Rubycon MBZ, Sanyo WG, or solid Polymer are all good choices to replace FZ. - Even though a ultra-crap brand FZ are high grade caps. [Grade meaning ESR/Ripple ratings, not quality.]

                Re: The Hall of Shame - Badcaps Photo Montage

                The only one I see was a 470uF 16V, which is rated 1800mA ripple, 0.022 ESR.

                  I am somewhat confused: do you mean in my photos?

                  I can see two 1500uF at 6.3 with blown tops in the first photo, and two 1000uF 6.3 with blown tops in the last photo.

                  I apologize for not posting better photos, but I didn't have my camera with me. I took those with my cell phone camera.

                    Here are some shots of a video card that was in a client's PC. User reported that the screen would blink or flicker.

                    I'll resize later if pics are too large.

                      Re: The Hall of Shame - Badcaps Photo Montage

                      Are you sure? I see a FZ 470 16V in the forth pic. I see now its different from the others. If you are going to replace the bad ones, you might as well do that one too, just because its not explody does not mean its not bad..
                      1500uF @ 6.3V is rated same as the 470uF 16V parts.
                      1000uF @ 6.3V is rated 1150mA ripple 0.036 ESR

                        I completely agree. What I had thought was that I should replace ALL of them. New caps aren't all that expensive. Trouble is, I am not sure the stupid card still works. Guess I'll find out.

                          Can anyone tell me 1) who made these POSs, and 2) what the information written on them and their colors mean?

                          For instance, in the photo of the single cap, the number 49, 470 (uf, I presume), the 6e, and the green stripe.

                          I apologize for the out-of-focus photos, but I will bring my "good" camera to work tomorrow.

                            Very hard to ID some polys.
                            If they are using a typical marking scheme.....
                            The 47 & 49 are -probably- a bacth/date code.
                            470 is the uF
                            6 & 16 are the volts. ['6' probably means 6.3v]
                            The 'E' and 'A' - series codes.

                              The green ones are sanyo/suncon CE-EX (.
                              These are hybrid polymer capacitors like the yellow fujitsu, and normally are reliable.

                                Here are the bad caps from my Samsung LN-S4041D LCDTV power supply board. Samwha 1000uF 10V 105C series WB. They're also marked "U8A" on one side. Not sure what that means, doesn't quite seem like a date code but I guess it could be.

                                Replaced with Rubicon 1000uF 16V MCZs from Badcaps.net. Four of them.

                                I was going to replace the other two, but I failed to notice on my initial inspection before ordering that the two other caps were 1000uF 25V. They're also series WB but they seem to be okay. I think I'll let 'em slide for now.

                                It's the 10V caps which are a known issue with this model.

                                This is the project which brought me to this site. Hopefully the information can be useful to someone else.

                                    Heh, yeah. I got that. It's right in my post.

                                    I just wasn't sure what "U8A" meant although I think it might be some kind of date code (other caps are marked U something A). There's also an "M" in parentheses after the 105C mark.

                                    But yeah, I've read that the 10V rated caps in these TVs are faulty and that the Samwha WB series caps are touch-and-go in general. (Someone here, somewhere, mentioned that.)

                                      I lost it in the speculation about what U8A is.
                                      I agree, it's a date code but I dunno how to decode it.
                                      - WB is an obsolete series. Not made any more.
