    1) What is the exact problem?

    2) Does the power LED turn green and stay on?

    3) Do you see any picture at all when connected to a working computer?

    4) Please post clear focused pictures using the manage attachments feature. Do not post inline.

    5) Post pictures of all your boards with a top down view (both sides).

      Re: Samsung Syncmaster 225BW

      I just wanted to pinch in, ive had problems with my bw 226, so i decided to look around for answers and found this.

      symptoms.

      Flickering.
      Loss of colour.

      First i looked around the internet, and i then discovered that i should check my caps, so i did, carefully disassembled the monitor and all caps were perfect.

      so i closed the case, and nothing had changed i did this 2 times more, with 3 the third try, i practially spilt the monitor apart, only the panel itself and the backlight(ccfl's)weren pryed apart(for obvious reasons). i were afraid i had to buy either a inverter board, or take readings with a tool i dindt have, but lo and behold. When i started my PC, the flickering were gone, and colors restored to their full glory.

      now, i understand why i really love this monitor.
      colours really ARE great.

      anyways,a bit offtopic, but if this ever gets a bad cap im going to exchange them thats for sure .

      also, a great forum and topic.>

      so thanks for helping out there, if it werent for the capicitator community my eyes would have bleed for...who knows...several months more.

      so. Thanks, Thanks ,Thanks and some more THANKS!

        I am a little confused, what was the fix?

          How do you know? Caps can fail and still look "perfect"...

            I don't know what the problem were but the fix i guess were that i simply had the case out and that removed dust, and..well i don't know..

            Oh, about the capacitors, i did not know that,is there anyway of checking without using a volt-meter?.


            so, it works . i just wanted to share because my symptoms were different than others because my colors were out of phase.

              Re: Samsung Syncmaster 225BW

              I have two of these beauties. I have repaired both of them. I read through this thread completely and noted that no one mentioned that there are two different cap set ups depending of the year the monitor was manufactured. One was a Dec 07 and the other Apr 06.

              The two 225BW monitors had different back steel shells, and more importantly a changed ratings for caps on the two middle ones.

              The older screen had two 680uF x 25 volt caps. The newer one has two 330uf x 25 volt.

              But when I started the project I just went and purchased 4 - 820uf x 35v and 6 - 330uf x 25 volt.

              It was not until after I had installed the caps that I found out that two of them where 680uf. The size of the stock caps are the same for the 680 and 330. So I have left them in so far and no problems as of yet. I have picked up the new 680uf x 25 volt caps but have yet to install them as the screen is working nicely.

              I did not change out the 47uf capacator.

              Note the stock 330 and 680 where almost the same size. The 820uf were physically larger so I laid them over to eliminate any interference issues. The new 680 are the same size as the old 680 and 330. The new 330 were/are small then the originals.

                It is not uncommon for manufacturers to change boards entirely and keep the same model number. This is why we always ask for pictures of your board. Additionally, we always recommend people list their capacitors and their values rather than rely on someone else's parts list.

                    1) Welcome to the forum!

                    2) Most members won't go to an unusual website for fear of viruses.

                    3) Might read retiredcaps comments on post #287. We need clear photos of top and bottom of the entire power board. Photo of logic board would also be good.

                    4) Better description of symptoms. Is there a flash or flicker of light when you power on? Any clicking sound? Anything?

                      i will take some photos later its 4:42am here yes i can hear some very silent clicking sound. "Is there a flash or flicker of light when you power on?" i dont know what you mean, but my screen is black all the time and when i plug power cable my power button starts blinking and i cant turn it off.

                        There are 2 revisions of the power board for the 226BW and other monitors who use that board (IP-45130A).
                        It says the revision on the board. Rev 0.1 has 1x330uF, 2x680uF and 2x820uF, Rev 0.2 has 3x330uF and 2x820uF.

                                Capxon all bulging. No surprise.

                                The standard recommendation here is to replace all the electrolytic caps. The exception is the biggest one which rarely, but not never, fails. I count 6 on the power board (not including the big one).

                                If you live in the USA, you can follow PlainBill's instructions for ordering Panasonic FM or FR caps (use FC as a 3rd choice) at

                                    Here is a list of vendors.

                                    Do not use some no-name unbranded cap. The caps must be low ESR. If you can't find Panasonic FM, try picking from this list.

                                      It might help if you told us what country you're in. Maybe a member can suggest a place to order your parts.

                                        Panasonic FC or FM are fine. I take it you're in Poland?
