    Samsung Syncmaster 214T

    I have 2 of these and they both are dim and flicker. They were manufactured Jan. 2006 and Feb. 2006. So I opened them up and sure enough they have bulging caps. They both have the same power/inverter and logic boards. The boards are IP-58130A but the difference is the caps on the power boards, c301 and c302 are 820uf 25v on one and 330uf 25v on the other(samsung's cap de'jour I guess).
    What should I replace these with 820's or 330's or can I use something else?

    Unless there are signs of someone opening up the monitors previously, I would replace the caps with the same uF per board.

    Assuming these are the correct dimensions ...

    For 820 use Panasonic FM at

    For the 330 use Panasonic FM at

    Don't forget to replace C107 as well on both boards.

      Hi i have had the same with 2 x 22" power boards
      one running 820's the other 330's
      I changed like for like replaced 820 with 820 and 330 with 330

      Check the size of the 820's they used 20mm x 10 on some 17" and 25mm x 10 on some of the larger lcds

      I thought it was odd that the same board had different caps but they worked fine once replaced and still do as far as i know

        Both of the above are good examples why we always ask people to post pictures of their specific boards and not to rely on someone's picture or configuration. It is not uncommon for manufacturers to change components or even entirely different boards, but keep the same model number.

          I'm going to replace all of them except the big one. The 820's are too tall, need something 20mm or shorter c110 and c111 are 820's also c112 is 330. I'm going to check digikey for FM or FC. I have a Nichicon PW for C107.

          That's what I thought also, same board but different caps?

            Panasonic FC is 20mm in height.

              I found Nichicons at 20mm also

              Had a 19" samsung once that used 680uf 25v and 2 820's at the transformers
              but had space to use 25mm tall ones laid on their side i found the Nichicons after the event

                  Just ordered the FM and FC's from Digikey, should ship tomorrow. A friend brought these monitors to me and said if I can fix them I could have one. Not bad for less then $20

                      Good deal. I was wondering where you got them. They look like nice 21 inch wide screen monitors.

                        Replaced the caps and both are working. Gotta love Digikey 2 days to ship from MN to FL via USPS.

                        Happy Holidays Everyone

                          Re: Samsung Syncmaster 214T

                          Hi Guys,

                          Memorial weekend is upon us so tinkering with broken monitors would be my way of honoring our fallen heroes. I will bring these monitors back to life!

                          I am repairing a same Samsung Syncmaster 214T.
                          Same symptoms of dim display and flickkering.
                          It has the same set of bulging caps: 820mf 25v and 330mf 25v.
                          Problem is, I do not have the same parts in stock. Local parts stores are closed.
                          While ordering it is the "DUH!" thing to do, I would like to ask the forum if I can replace it with something close that I have on hand.

                          For 330mf 25v: I have 330uF 35v and 470uF 25v
                          For 820uf 25v: I have 1000uf 25v

                          What is the science behind replacing it with:
                          1) Slightly higher capacitance with the same voltage rating
                          2) Same capacitance with slightly higher voltage rating
                          3) Slightly lower capacitance with the same voltage rating

                          The word 'slightly' is relative but the caps I have on hand are the closest replacement part avalaible so I am hoping someone can give me an Electronics 101 lesson.

                          Thanks!

                              The 330uf 35volts will be fine,and have replaced 820uF with a 1000uF before,with no problems.Electrolytics are nomally rated at + or - 20%,so the 820 COULD in fact be between 656uF and 964uF,,using the same percentage then the 1000 COULD be between 800uF and 1200uF,so theres a good chance thats why there is usually no problem

                                Okay,
                                For those of You who have 330mf and 850mf. As long as voltage is same or at least slightly higher tolerance. It will work. I prefer sticking with SAME VOLTAGE, though. And for the capacitance, a slightly higher rating is aceptable. I have a inverter board 'NB-20 model= ip-58130a' with 2 each 330mf-25v and 3 each 1000mf-25v capacitors. from manufacturer. this circuit area is not too critical about same value Caps as some other boards or area circuits on this board in LCD screens.

                                As for actual physical sze of caps , be sure to double check with your normal supply Rep. sometimes if mention limited space and size....they may may have shorter caps in their inventory upon request. Ran into this in the past....one example of , it never hurts to ask.

                                ------------------------
                                these caps appear to be problem in compact areas such as Flat screen TV( monitors) and compact or small computer cases in my field...not enough breathing room, air flow, and slow or bad fans allowing overheating in the area of the Caps. Tolerance issue with Caps , I would say.



                                .....Good Luck to all with your Caps issues.

                                  Hey guys, thanks for the information. I have two Samsung 214t monitors that both died around the same time, and was able to repair one last week with this info.
                                  Unfortunately the other monitor still only flashes for a second and remains on with a blank screen.
                                  Hopefully it isn't a sign of something major that is broke and I thought I wouldn't give up yet.

                                  I did see another person with this problem, but he didn't provide any information other than it being a green - 3 Amp Pico Fuse with a picture of the item.
                                  The only thing remotely resembling the image he posted was a 3A 125V Axial Fast Acting Capacitor, but I don't see this on the board itself.

                                  Does anyone has an idea of what else could cause the blank screen? All of the capacitors were replaced with the same specs and same parts as the now working monitor.

                                    1) 2 seconds to black can be

                                    a) bad caps
                                    b) bad inverter transformer
                                    c) bad ccfl and/or wiring

                                    All are discussed in more detail in posts #13 and #14 at

                                      Try swapping the guts from the good monitor to the panel of the one that has 2 sec to black. If the problem persists, you know it is the ccfls. If the problem goes away then it is an issue with the board itself. These are great monitors, I am looking through one as I type this very post that I successfully re-caped. I also fixed a 204T that had a bad startup cap, the small 22uf or so cap (c107 above), but if you are getting a picture with a flashlight, you are way beyond that point. Just something to keep in mind. Also, if a fuse was blown you probably wouldn't even get 2 seconds to black.

                                        It's funny that you mention that, because I actually did that before.
                                        I didn't look into it further, because I got the other monitor working with its board instead.

                                        I actually don't get 2 seconds to black. The screen will literally flash on and off immediately. Is the ccfl an expensive replacement?

If the problem goes away then it is an issue with the board itself. These are great monitors, I am looking through one as I type this very post that I successfully re-caped. I also fixed a 204T that had a bad startup cap, the small 22uf or so cap (c107 above), but if you are getting a picture with a flashlight, you are way beyond that point. Just something to keep in mind. Also, if a fuse was blown you probably wouldn't even get 2 seconds to black.
