          I should make a world map of all the people I have helped. Should be interesting to see all the locations.

          I'm glad your monitor is working again.

            Re: Samsung SyncMaster 226BW

            My Samsung 226BW had the issue where it would beep in power save mode. When coming out of power save mode I would have switch from digital to analog and back before I would see a picture on the screen. I was able to fix the monitor by replacing all capacitors except for the big one. Thanks to everyone on this board for your help and encouragement (this was my first time soldering anything).

            Quick question. My 5x 820uF 25v capacitors are 25mm high and are touching the top of the chassis. Is this going to cause any problems? For example, do they need room on top for airflow? If they go bad in the future and begin to bulge, will they explode? Just want to make sure I'm not creating a safety hazard.

              If the caps are suited for the job, bulging will be a very slow process and occur only after several years of use. There's no risk of explosion.

                  Using used caps that may or may not be low ESR is not a good idea. A SMPS requires low ESR caps like Panasonic FR, FM, or FC series.

                  New caps are less than 50 or 60 cents each and quality ones like the Panasonic will last much longer than Capxon (very poor quality).

                    Re: Samsung SyncMaster 226BW

                    I too would like to thank this community for helping me diagnose the problem I was experiencing with my SyncMaster 226BW Rev 0.1 monitor.

                    The flickering started back in the Spring and got steadily worse until this Fall when I decided to leave the monitor all the time. Not the smartest idea, I know, but it was either that or actually try and fix the thing! I had actually found this forum last spring, but the idea of desoldering/soldering seemed too daunting to attempt.

                    Leave it to mother nature to finally get me off my butt and do something about it; about a week or two ago my part of Los Angeles experienced pretty bad winds, and I lost power more than few times. But it only took the first time to realize that my monitor was pretty much dead. It did power back up after the first outage, but it took a few hours! After the second outage, I didn't even bother to try and see if it would come back.

                    Luckily I have two of these mounted side by side, so at least I was still able to get online. My first stop was Amazon, and I figured I would just replace the monitor. But then I remembered having found this thread, and here I am.

                    Thanks to all of the helpful posts I have found all the parts I need at both Digikey and Mouser, but I still have a question that I am hoping someone can help answer.

                    I've never desoldered/soldered anything before, but I'm typing from the Hackintosh that I built a few years ago and I am pretty good with technology. Anyway, after reading a few reviews/threads, I purchased a desoldering iron from Radio Shack for $11. I was also thinking of getting another el-cheapo iron from Radio Shack for the soldering job, but discovered that the Radio Shack Desoldering Iron will accept a Weller PL111 tip, available for $5.35 from Mouser.

                    So my question is would it be okay to preform the soldering with the Radio Shack Desoldering Iron and the Weller PL111 tip, or would the iron be difficult to solder with because of the odd 90 degree angle? If so, are there any inexpensive soldering irons you would recommend for this job? I don't anticipate having to use the iron again, unless the other monitor goes bad as well.

                    Thanks again for all the great threads and comments,

                    Bruno

                      I haven't used a desoldering tool to remove a cap from a single layer board in years. Personally, I think you are optimistic to believe you will be doing this only once. First you will fix this monitor. They you will decide to preemptively recap it's companion, then someone will offer you a TV...

                      Still, for a single recap job (or two) this soldering iron should do exactly what you need. Instead of a dedicated desoldering tool I use a dissecting pick to clear the molten solder from the hole. If your local Frys Electronics has it in stock, you can spend a few hours drooling over the other items in that aisle.

                        Hey Guys,

                        I'm having the same problems with syncmaster 226bw. The screen (backlight) goes on for about a second and then turns of. I have replaced the following caps:

                        3 x 25V, 330UF, 105GR
                        2 x 25V, 820UF, 105GR (replaced with 2 x 25v 1000UF)
                        1 x 50V, 47UF, 105GR

                        The problem is still the same. The only cap that is still there is the big one, 450v 150UF. Should I replace this one as well?

                            Not at this time unless there are physical signs it is bad (leaking, discolored leads, etc).

                            What brand and series of caps did you use for replacements?

                            Have you compared the resistances of the secondary windings on the inverter?

                            From a cold start, does the display have a pinkish tint in the first few seconds?

                            Do you have a spare set of CCFLs to use for testing?

                              Thank you for your answer. The 450v is not showing any signs that it is bad. I think the brand is "Nippon", they are all rated 105 degrees.

                              I'm not very good with electronics, but I think I know what you mean.
                              The one on the side of the power plug is: 1098 ohm
                              The other one: 1117 ohm.

                              I just ran a cold start, doesn't seem pinkish. Just normal image and a tik, tik, tik sound and than it shuts down.

                              I don't have spare ccfls unfortunately.

                                The one on the side of the power plug is: 1098 ohm
                                The other one: 1117 ohm.

                                I just ran a cold start, doesn't seem pinkish. Just normal image and a tik, tik, tik sound and than it shuts down.

                                I don't have spare ccfls unfortunately.
                                The symptoms indicate 'two seconds to black'. Possible causes include capacitors, transformer, CCFLs and wiring, and the protection circuit.

                                The resistance test indicates the transformers are good.

                                At this point you have three options.

                                1. Check and report the name and series codes on the capacitors.

                                2. Open the LCD panel up and check the wiring to the CCFLs.

                                3. Buy a new monitor.
                                For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

                                Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

                                  This is what I could find about the caps:

                                  Nippon KMF Mini, High Freq. Use, Low Z, 330uF-25V-KMF
                                  Nippon SXE Mini, High Freq. Use, Low Z, 1000uF-25V-SXE
                                  Nippon KMF Mini, High Freq. Use, Low Z, 47uF-50V-KMF

                                  I don't know if this helps.

                                  Could I try to start the monitor with less ccfls connected? Maybe this could help determine if there is a wiring problem?

                                    I am unimpressed with the specs on the replacement caps. I prefer Panasonic FM; Panasonic FC are regarded as marginally low ESR. The KMF and SXE have an impedance roughly 4 times greater than equivalent FC caps, and a ripple current rating 1/4 less.

                                    Still, I'm not sure that is the cause of the problem. Did the symptoms change after replacing the caps?

                                    There is a test you can do that involves disconnecting the CCFLs. It may or may not produce results.

                                    With power off, disconnect all but one CCFL. Turn on the monitor and the backlights should come on briefly. Repeat for the remaining CCFLs. If one CCFL fails to light, it is defective. If all CCFLs fail to light, they are driven in pairs, and the upper pair must be tested together, and the lower pair tested together.

Personally, I think you are optimistic to believe you will be doing this only once. First you will fix this monitor.

                                      Still, for a single recap job (or two) this soldering iron should do exactly what you need. Instead of a dedicated desoldering tool I use a dissecting pick to clear the molten solder from the hole. If your local Frys Electronics has it in stock, you can spend a few hours drooling over the other items in that aisle.

                                      Thanks for the reply PlainBill! I had already thrown out the Radio Shack packaging, so I decided to keep the Desoldering Tool and it worked pretty well for me; I was able to desolder the 3 bad caps and remaining 2 CapXon's last night in less than 10 minutes and all went well.

                                      You are probably right about this not being a one time thing; I spent a lot of time in Fry's and they had a lot of cool stuff. I did get the $2.99 Fry's special you suggested and also picked up some 60/40 solder for $2.99, and I'm going to solder the caps from Digikey (they came on Sat) tonight.

                                      I can't believe that I considered buying a new monitor; this repair cost less than $13! Thanks!

                                        The $2.99 soldering iron should do the job on a single layer PCB. I use the "sort by lowest price" ebay method to buy my soldering irons and they work fine. I recently recapped a Samsung LCD and (6 caps) and I was done in less than 20 minutes.

                                          Just to let you guys know. I've opened my monitor completely to take a further look at the lamps. I found the upper 2 ccfls are broken. The glass is broken and it's all black at the connection.

                                          I don't think I'm going to repair it. I can't find a supplier for ccfls at a reasonable price, and I'm afraid something is wrong at the board that will make the lamps break again when I've replaced them.

                                            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...

                                            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...

                                            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 time—like after playing a game—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...
