    Re: Samsung SyncMaster 226BW

    There are a number of things that can cause the 2 seconds to black. Retiredcaps has a step by step guide on the most common causes and how to test for them I would say that's worth a try.

    The last couple of monitors I have had with 2 seconds to black had faulty CCFL connections. This can cause the IC controlling the inverters to shutdown after a few seconds.

    To test for this you really need a spare CCFL or 2 do you have any spares?

        Re: Samsung SyncMaster 226BW

        Hello..,

        Thanks for your replies..!

        Jasgriff.., I have a few 17" monitors that I could disassemble.., do the spare CCFL's have to be the same size.., or can I use one of my 17" units..?

        I have repaired two other monitors with the Bursting Caps issue and they both work great.., I guess this unit has another challenge.

        selldoor.., thanks for the link to the guide.., I will have a look at that today.


        .... info is much appreciated..!!

          You dont need to completely disassemble -just open up disconnect ccfl leads and
          plug in to sockets on 226bw . May be a struggle and 17in might have 2 bulbs and 22 4 bulbs - in which case substitute one lead at a time-
          17 inch is usually ok for a short test Unless the fault recognition system is so accurate that it spots the imbalance. In which case it will still just shut down.

          Another thing that sometimes works is that top bulbs wear out quicker than bottom ones due to more heat and if you change the leads around it may work.

            Ok..,

            I have another Samsung monitor.., a 20".., I didn't really want to use it.., but decided to proceed.., so I plugged the CCFL plugs of the 226BW.., into the 20" panel.., and the screen came on full and bright.., I turned it off after @ 20 seconds. I turned it on a few more times and it remained on steady until I turned it off.

            Also.., before doing the above.., I unplugged all four CCFL plugs on the 226BW.., then re-connected one plug at a time and turned the power on.., to test if a lamp would come on.., as suggested in 'retiredcaps' guide.., post #20.., the result was that a lamp did come on...., for 3 of the 4 plugs.., I marked the one plug position that did not illuminate a lamp.

            So I gather that the '2 seconds to black' is caused by this CCFL connection or lamp.

            I assume the next step is to disassemble the panel and check the connections.., wiring and bulbs..?

              Re: Samsung SyncMaster 226BW

              That might suggest that the low voltage wire has come off the end of the CCFL tube. You will need to take the panel apart to have a look.

                Did you just try One lamp in the plug that didnt work - try another lamp.
                Did you try the lamp that didnt work in another plug- try it

                Just trying to confirm it is a dodgy lamp/wiring or dodgy socket.

                Just re read what you said - you are saying that the panel off the 22 inch
                lit perfectly when connected to the 20 inch?
                If that IS what you are saying then the panel lights & wiring on the
                22 inch are probably ok and the fault is in the inverter.

                First re try the original 22 inch panel back in the 22 inch monitor- just in case it was not connected properly in the first place.
                then if that doesnt stay on can you Plug the 20inch panel into the 22
                and see how long that stays on.

                  Just trying to confirm it is a dodgy lamp/wiring or dodgy socket.
                  => Ok.., good suggestion to try another lamp plug into that board output.., I did that.., and that output did light the other lamp. I also did try the lamp plug that didn't work into a different output.., and it didn't work in the other known good output.., so it would appear that it is that one lamp that is the issue.

                  => Ok.., clearity.., sorry.., here is how I should have worded it.., I plugged the CCFL plugs of the 20" panel.., into the board outlets of the 22" - 226BW...., and the 20" screen came on full and bright.., I turned it off (22" board & 20" screen) after @ 20 seconds. I turned it on a few more times and it remained on steady until I turned it off.

                  => I completed your suggestion as above.., re-tried 22" panel with 22" board and it produced the '2 seconds to black'..., also re-tried the 20" panel with the 22" board.., and the 20" panel stayed on good and bright as long as I left it turned on.

                  In summary..,

                  ... initially I unplugged the 22" CCFL plugs from the 22" board.., and tried them one at a time and 3 of 4 turned on for 2 seconds then black. I then tried as suggested.., and plugged the 'non-working' lamp plug into a different 'known working' board outlet.., and that non-working lamp did not work on the different outlet. I then plugged a known working lamp plug.., into the board outlet that I previously marked as not working.., and the lamp did come on with that outlet.., so that outlet does work.., but that one lamp does not work on a different 'working' outlet position.

                  ... I then re-tried connecting my 20" panel to the board of the 22" monitor.., and the 20" panel turned on correctly and bright.., for as long as I left the power on.., so the 22" board operated the 20" panel correctly.

                  I will work at taking the 22" panel apart to have a look.., I just hope the lamp is not shot.


                  .... your assistance is much appreciated..!!

                    Im sure the CCFL will be fine and it will more than likely be the wire that's come off the end. When you get the the bulb be very very careful and remember when you sake the silicone cap off the end do it very carefully as you will need to put that back on.

                      There is lots of info on this site regarding ccfls - problem is finding it
                      This is a good thread and it has links to examples of bad wiring for you to look out for.
                      https://www.badcaps.net/forum/showthread.php?t=11934.

                      As Jasgriff says take great care - lights are VERY fragile and wiring
                      disintegrates with the heat. Something to tackle when you are not going to be rushed.

                              Hello everyone. I'm new to capacitors and all this fun stuff. I was hoping i could get some help. I need some new capacitors due to some flickering. I have my monitor ripped apart currently. I know someone on this thread named toasty was able to help someone named krickster on page 2 about the same problem with the same capacitors i need. Though his order history from digi key is no longer viewable.

                              The power supply model number is:
                              IP-43130A

                              226BW-VE REV0.0 2007.04.18

                              Monitor type is LTM220MI-L01

                                New capacitors will have the values written on the side of them. If you list them on here then I am sure one of us can point you in the right direction.

                                    Radio Shack will likely NOT have low ESR capacitors which are required in a SMPS power supply. See my standard response at (regulars may skip)

                                      Are you going of what you have measured them as or whats written on the side of the caps?

                                      Same comment as above with regards to radio shack. I am sure digikey don't take that long to deliver them out to you and you will save time and money in the long term.

                                        These were the ones that were posted on kricksters post located on page two. I did go to radio shack and yes, they had nothing. I think my answer is actually on page two but It's kind of confusing

                                            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...

                                            Syncmaster T220 flashing on and off
                                            by Kyrtapy
                                            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.

                                            ...

                                            Samsung SyncMaster 215TW buzzing / lightning in power board socket
                                            by nh2
                                            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...
