Re: Samsung Syncmaster 225BW
Got it working! I purchased the following:
2 565-1800-ND (ELXY250ELL821MK20S) 820uF 25V
1 565-1547-ND (EKY-250ELL331MJC5S) 330uF 25V
2 493-1544-ND (UHE1E681MPD) 680uF 25V
1 493-1934-ND (UPW1J470MPD) 47uF 63V
but I actually only installed the first two lines as they were the only ones obviously blown and I am a very impatient person. Anyway, this was my first time soldering anything and I got it done. Really happy about that. Thanks for the help.

Re: Samsung Syncmaster 225BW
Hi all,
I week ago my Samsung 225BW screen died. I followed the directions in this thread and replaced 5 of the capacitors. The only difference in the new capacitors that I installed is that instead of the two 820 mF 25V capacitors I put two 1000 mF 25V capacitors, and instead of the three 320 mF 25V capacitors I install three 320 mF 50V capacitors. I am bare in electronics and I am not sure if this is a huge problem, but the monitor worked just fine after replacing the capacitors. The guys at the electronics store told me that the voltage on the 320 mF capacitors is not a problem. However, since yesterday the colors on my monitor are not stable, they seem to constantly change from more reddish to normal colors.
Does anybody have an idea why this is?
Thanks in advance,
Petar

2) What brand and series did you use for the replacement capacitors? It matters if you used general purpose caps or low ESR (ohms) caps.
3) Members here advise that you replace all capacitors because capacitors die from age, heat, and shoddy build quality. Capacitors DO NOT have to be visibly bloated in order to bad. They can be out of tolerance uF (a 1000uF measures 20uF) and/or have high ESR (ohm). A multimeter will be insufficient to test for ESR. For that you need an ESR tester which costs between $50 and $300.
Most members here will recommend that you replace ALL capacitors with reputable brands from reputable sellers. Brands like Rubycon, Panasonic, and United Chemicon are suggested. A list of recommended caps can be found at
https://www.badcaps.net/forum/showthread.php?t=2280
4) You should take the lcd apart and make sure all the cables are tightly secured especially the flat cables going to the t-con panel. These cables are fragile and can be easily dislodged.
5) Did you reset the lcd back to factory defaults?
6) Did you try using a different VGA or DVI cable?--- begin sig file ---

Re: Samsung Syncmaster 225BW
Hello everyone, recentely my Samsung Syncmaster 225ms broke down on me. I know the screen is fine because when I turn it on, I can see my computer monitor for a quick second and then the screen goes dark. If I shine a bright light onto the screen I can see my desktop, but only faintly. After reading about 5 pages into the fourm I am sure it is the capacitors that are broken. The only thing is, I don't know where to get or what kind of replacement capacitors are. I have gone to digikey and followed PlainBill's seach guide, but nothing came up. Samsung 225ms
In the pics below the first picture( a bit darker than the others) has the bad capacitor(at least I think it is) But I plan to replace all of them for more reliable ones. Can someone please help me figure out what capacitor I need to buy?
Thanks you so much!

1. Measure the tallest cap on the board. That defines the tallest cap you can use.
2. Make up a chart showing the following information for each of the 10 caps you are going to replace: Capacitance, voltage, diameter, location.
3. Use the procedure I wrote for selecting caps. Double check the height; you don't want to choose one that is too high.
4. Post the proposed list. Someone will double check it.

Re: Samsung Syncmaster 225BW
What do you mean by each of the 10 caps I am using? Sorry, I am new to this. Also where would I find the capacitance, and what do I use to mark the location? Hopefully the pictures I took could help?
Also I don't really know how the chart would be set up, do you have an example of some sort I could see and mimic?

So the table would look like this:
C220 10 mm 470uF 25V
C221 10 mm
C222 10 mm

Re: Samsung Syncmaster 225BW
Originally posted by PlainBill View PostLook at the board. Each capacitor has a location number next to it. In the first picture I can read the location for one of the caps - C220. I also can make out the value - 470 uF, and the voltage - 25V (I think). In the last picture I can identify 3 more location numbers - C222, C221, C232. In the upper left corner are three more caps, at top center are two more tiny ones, and near bottom center is the last one; it's location number ends in 7. It's likely C220 is 10mm in diameter, 16 mm high.
So the table would look like this:
C220 10 mm 470uF 25V
C221 10 mm
C222 10 mm

Also I need a desoldering pump, would I find that at Radio Shack as well? Or maybe frys?
thanks so much
EDIT: http://www.radioshack.com/product/in...ductId=2103624 For instance would that replace my current 470uF cap fine?

Re: Samsung Syncmaster 225BW
Soldering supplies you can pick up at Radioshack or Fry's. DONOT purchase caps from them as they are the wrong type.
I supsect you are entering the wrong info at the digikey site. Using C220 from your list as an example, try the following:
at digikey.com. In the part search box enter:
panasonic fm 470uf 25v
press the "go" button.
You should get a couple of hits that match your criteria of size and height. Some caps you can buy in multiples of 1, but others require a larger purchase and some are out of stock. Obviously, you want to purchase in multiples of 1.
If you don't see the cap you want, then in the above search string substitute fm with fc or fr.Last edited by jetadm123; 02-21-2011, 10:08 PM.

P10314-ND for 3.3uf 50v caps.
P10267-ND for 47uf 25v cap.
P12417-ND for 680uf 35v cap.
P12379-ND for 1000uf 25v cap.
If someone could confirm that, that would be great. Also a note: I mistakingly put that the 680uf cap was 650 in the chart. Disregard that, it is 680uf not 650.

P10267-ND for 47uf 25v cap. Check
P12417-ND for 680uf 35v cap. Check
P12379-ND for 1000uf 25v cap. Check
A couple of very minor points. As a matter of preference, I prefer having the list of capacitors embedded in your reply, not as a separate file - it makes checking easier. Also, there is no point in listing the height of all caps; all we have to know is the maximum height allowable for any cap. That makes it easier for you.
And that is pretty much the list of caps I would have come up with. When ordering, specify USPS First Class mail for fast, inexpensive shipping. And if someone tells you they prefer United Chemicon or Nichicon low ESR caps, don't argue - both brands are also excellent.
