    I've seen that myself, but then if you can get your hands on an ESR meter, you'll find that most of the time they are out of spec. And in the case of the list of known bad brands,replacement is a preventive measure anyways ...

      Re: Samsung SyncMaster 226BW

      I'd just like to say a huge thank you to EVERYONE in this thread.
      huge.
      HUGE.
      Everyone here helped me with getting my 3 year old 226BW back up and running after flickering (probably really close to a seizure there at the end) at power on for about a week.

      From the part numbers to the multiple parts vendors (Digi-Key).

      Opened up the monitor and checked for what everyone was describing, and there they were. The 2 820's and the 330 were bulged at the top, all caps were CapXon btw.

      Two day wait for the parts from Digi-Key and the 3 bad capacitors are sitting right next to my working 22" monitor.

      So, thank you everyone.
      You're awesome.

          Hi, just wanted to let you know that I popped up my 226BW, I saw the caps and wasn't sure of the specs. I found this thread an ordered a couple of new ones from mouser. Just replaced the three close to the inductor. Now the screen works perfect again.

          I took some images of the steps in my replacement procedure and if any one needs them for something I am glad to share.

            You can upload them here by clicking on "go advanced" (below the quick reply under the last post in a thread) and then using the "manage attachments" button below the post editor.

            Images in jpg format need to be smaller than 2000x2000px and 3.81MB.
            Shouldn't be an issue most of the time though.

              Re: Samsung SyncMaster 226BW

              Hey,
              i got the same problem!
              I life in Germany and i cant find a 820uf 25v cap on the german net to buy.
              Is there an other option to fix the 226bw? could i just use 2x 820uf 35v or 2x 1000uf 25v.

              I found the little 330uf 25v. ( http://www.conrad.de/ce/de/product/4...45812&ref=list )

              The 2 other caps (680uf 25v are looking perfekt)(but there available)

                2x 820uf 35v if they fit (height) will be fine.

                    you could have used 16V caps instead, as they're on the 13V rail.

                    oh and by the way.. just goes to show how expensive conrad is in comparison.. (same cap, same values)

                      ok, thanks for the clues.
                      I will remember them in case that my second 226bw dies.
                      i love this forum!

                        Re: Samsung SyncMaster 226BW

                        Hello all,

                        Another Samsung 226bw with bad cap problems. It has been ongoing for a few months but I've not had the time until now to try and fix it. Yesterday it took 3 hours for the monitor to finally warm up so that was the last straw. Opened it up, figured out which caps I had and what to replace them with from the info contained in this helpful thread.

                        I just placed an order at mouser.com for the following:

                        Mfr. #: 1 x EEU-FC1H2R2
                        Desc.: Aluminum Electrolytic Capacitors - Leaded 2.2UF 50V ELECT FC

                        Mfr. #: 1 x EEU-FM1H220
                        Desc.: Aluminum Electrolytic Capacitors - Leaded 22UF 50V FM RADIAL

                        Mfr. #: 1 x EEU-FC1H470
                        Desc.: Aluminum Electrolytic Capacitors - Leaded 47uF 50V

                        Mfr. #: 1 x EEU-FM1E331
                        Desc.: Aluminum Electrolytic Capacitors - Leaded 330UF 25V ELECT FM

                        Mfr. #: 5 x EEU-FM1E821L
                        Desc.: Aluminum Electrolytic Capacitors - Leaded 820uF 25V ELECT FM


                        Decided against replacing the big 150uF cap at position C105 as it looks to be in fine shape, and considering only replacing the five 820uF and one 330uF caps as they are the only ones that are bulging at the top... ordered the rest just in case.

                        Picture of my board below.

                        Will post with results when I complete the repairs. This is my first time soldering anything, wish me luck!

                          I am experiencing a similar problem with my 226BW(S Panel).

                          It's not exactly the same,it doesn't go black and it doesn't function properly when it's heated.In my case,there are lines and boxes all over the monitor flickering very rapidly and it's more visible on white/"soft" colors.

                          It started yesterday acting really crazy,constant flickering and I couldn't watch the monitor for more than 5 minutes.This morning it was better,happening once every 5 minutes and at a much lower scale than yesterday.

                          I was able to find only 2 caps out of 7 in the market,and when I opened it only one of them didn't have a straight top,it was like the ones in the pictures in this thread but with no sign of leaks.The others were fine.I replaced the damaged one but the problem is still here.

                          I have plugged in an old CRT with a VGA to DVI adapter and a LCD TV and they were fine.I also tried a different DVI cable and power cable.

                          I will buy all 7 capacitors and change them all just to be safe but I wonder,could something else cause this problem?The other caps seemed ok,but even if I change them I don't think it will help.

                            Could be bad soldering on the logic board, or a dirty LCD ribbon. Reseat the ribbon cable between the logic board and the LCD and see if the situation improves.

                              Thanks for the reply.I will try it when I open it to replace the caps.Anything else I should check?Is it possible for a cap to be dysfunctional even if it looks ok?

                                  Yes, and a bad cap on the logic board could give the symptoms you are describing. First recap the whole power supply then if it still doesn't work we'll try other things.

                                    I opened it once again,I reseated the LCD ribbon,caps are fine,took a look everywhere and it looks fine.I'm am starting to worry about a faulty GPU,even if I connected my LCD TV with a HDMI to DVI cable with no problems.

                                      Re: Samsung SyncMaster 226BW

                                      Hello all. Thanks for all the help you provided to so many people.

                                      I had the flicker problem on my 226bw, and sent it to a friend who changed the 2x820uF capacitors with 2x1000uF ones. Then when i received the monitor back, i noticed it was dim and yellowish.

                                      Then i googled and come here, bought myself a kit of low esr capacitors and changed myself all the 5 capacitors. To notice that i cant find 820uF capacitors here, so i also used 2x1000uF.

                                      The screen is better, less dim and yellow, but still... hasn't the full image quality of a 226bw.

                                      My question is, can it be due to the change of de 820uF to 1000uF? or should i look for something else ?

                                      Thanks in advance.

                                        1) What brand and series of capacitors did you use for replacements?

                                        2) What do you mean by "full image quality of a 226bw"? Are you using the highest resolution? Reset the monitor to factory defaults?

                                        3) The standard procedure here is to post clear focused pictures of all your boards using the manage attachments functions so the pictures are attached to this forum. Please do not post inline because it slows down the loading of pages.

                                        After you have posted the pictures using manage attachments, we can suggest test points.

                                          Thanks for your quick reply !

                                          I'm currently not at home, so i cant provide those infos, i will have to open the monitor again and take photos.

                                          By full image quality i mean that "excessive" brightness and white image that we can see in a 226bw, and using 1680x1050.

                                          My main doubt is if the change of 820uF to 1000uF could significantly affect the ccfl power in a way that the screen would appear more dim than normal.

                                          Either way, i'll post photos soon.

                                          Thanks!

                                            Hi folks,

                                            I'm new here and was wondering whether you might be kind enough to give me some advice on troubleshooting the following problem:

                                            Quite a few years ago now, a couple of years from new, my Samsung Syncmaster 740BF LCD monitor starting playing up by making a buzzing noise and then the display would go blank. I seem to remember the blue power led would also go off when this happened but that I'm not 100% sure of. By pressing the power button I do remember I could at first get it working again but eventually the problem would come back. At the time I had read about...

                                            Samsung SyncMaster 955DF dim image fix
                                            by rattlesnake
                                            This display looks a bit dim but the image is otherwise fine. I already set the contrast to 100 and the brightness to 50 (more than that is counterproductive, it becomes hazy).

                                            To enable extra tuning, I have to enable the "Highlight Zone" function and stretch it to full screen. That way it looks really bright/intense and really good! I wish I could set it permanently like this, but as soon as you change the display mode/resolution or you turn the monitor off, you lose the "Highlight zone" config and you have to manuallly activate it again. Also, the manual says...

                                            by vincentedel
                                            Hello,
                                            I'm having an issue with the Samsung 740n's phase control setting. When I use the automatic adjustment, it sets the value to around 54 (with a range of 0-100), and the picture looks clear and sharp. However, after some timeβ€”like after playing a gameβ€”the text starts to look blurry. When I auto-adjust again, it may increase the value to 80, and everything becomes sharp once more. Yet, after a while, whether it's a few hours or a day later, the same blurriness returns, and I have to adjust it again.

                                            I'm using the Samsung 740n monitor drivers instead of the default plug-and-play...

                                            Hi, my monitor started having an issue. While there is a vga or dvi cable connected to the monitor, the screen flashes on and off. If there is no cable connected, it shows the no signal warning without any issues.

                                            I tried different cables and nothing helped. I also tried using different monitor with my pc and the monitor was working normal so my computer is not the issue.

                                            Last year I replaced two of the capacitors because they were leaking and the monitor was having trouble starting up and it fixed the problem, but now, no leaking capacitors on the PCBs.

                                            ...

                                            This is my first post here. I just fixed my first 2 broken displays by replacing broken capacitors (Samsung SyncMaster 226BW, and Samsung SyncMaster 213T). But I have a third one I'm unable to fix, and am eager to fix as well:

                                            My Samsung SyncMaster 215TW makes a buzzing / hissing sound when turned on.

                                            The sound is louder the brighter the monitor is, e.g. in the "Game" preset is is even louder than in a softer preset.

                                            Opening up the monitor and unplugging the small socket cables that run from the power board to the LCD, I can see a small blue...
